Water quality is a critical concept for undergraduate students studying Earth Sciences, Biology, and Environmental Sciences. Many of these students will be asked to assess the impacts of a proposed anthropogenic activities on human water resources and/or ecosystems as part of their future careers. This module engages students in exploring factors contributing to the variability of nitrate in surface waters; one of the most common contaminants found in US rivers. Students will utilize real-time nitrate data from the US Geological Survey to statistically evaluate water quality impacts and to identify their causes.

Learning Goals

Learning objectives:

This module introduces students to the following Scientific Concepts:

• The concept of "concentration" with an emphasis on nitrate.
• Natural and anthropogenic fluxes to the nitrogen cycle.
• Impacts of elevated nitrate on drinking water quality (i.e. blue baby syndrome). Passing reference is made to ecological impacts, however, because these impacts vary from environment to environment, we only introduce concepts of eutrophication and hypoxia.
• An introduction to water law and water management.
• Exploration of point-source, non-point source, and land use impacts on water quality.
• Exploration of the nitrogen cycle.

Quantitative skills gained by students from this module include:

• An understanding of data variability, both natural and anthropogenic.
• The calculation and interpretation of probability.
• An understanding of how to access online datasets from the USGS.
• The ability to perform calculations and generate graphs using MS Excel.
• An appreciation for the value of large datasets.

Context for Use

This complete module is designed to be implemented over four 1-hour classes, requiring internet access and Microsoft Excel for students. Activities may be broken up and used separately as instructors see fit. This module is intended for introductory to mid-level, Earth Science, Biological Science and Environmental Science students. It is helpful if students have a little knowledge of chemistry, however, this is not required. It will also be useful for the students to understand the fundamentals of the hydrological cycle prior to this module as concepts of storm water runoff and base flow play a key role in the interpretation of the results of Activity D. The Excel skills used in this activity involve calculating probability and generating a graph.

Module materials can be tailored to increase or decrease the background information depending on students' quantitative skills and interests. This module can also be taught as Part 2 of a three-part module sequence, beginning with Module 5) Stream Discharge and concluding with Module 7) Nutrient Loading.

Each group needs:

• Data Collection Worksheet , one per student
• 2-liter plastic bottle cut in half horizontally, as shown in Figure 1; ask students to bring empty bottles from home or get from local recycling center near you; wash before use; consider using the same ones used in Lesson 4's This Landfill is a Gas activity.)

• 3-inch square of mesh, such as fine nylon screen or fine cheese-cloth
• 1 rubber band
• 1 spoon or other stirring utensil; a chopstick works well

To share among all groups:

• filter materials, such as filter paper or large coffee filter (at least 6" in diameter), 6 cotton balls, ~6 cups soil, ~6 cups sand, 1 dozen large and small pebbles (total), ~6 cup activated charcoal (such as used for potting plants and in aquariums)
• aquarium aerator or a mechanical stirrer/mixer; aeration pumps for fish tanks work well
• measuring cups
• 2 large jugs/jars, ~1 gallon size, such as plastic gallon milk jugs with lids; for mixing/storing "polluted water" (recipe follows)
• "polluted water" made by mixing the following items in amounts at the teacher's discretion: water (enough to fill the jugs/jars ~¾ full), green liquid food coloring, soil, organic matter such as grass clippings and orange rinds, dishwashing detergent, vinegar, baking soda, salt, pepper, pieces of polystyrene foam (foam peanuts), small pieces of newspaper, and your own ideas for other items

Due to its incredible chemical properties, water is often considered the "universal solvent." It can mix with organic (natural) or synthetic (human-made) substances. Some of these products easily break down in water, while others break down very slowly, or perhaps even never. Water naturally cleans itself via filtration through the ground and evaporation via the water cycle.

At one time, communities disposed of their waste and garbage directly into lakes, streams and oceans. Now, most countries require that unclean (contaminated, polluted) water be treated before it is permitted to be released into natural bodies of water like lakes, rivers and oceans.

Generally, three different ways are used to treat raw sewage (waste) water before it is released. First, the liquid is given time to settle and then is exposed to oxygen by stirring or bubbling air through it (aeration). This helps many harmful organic pollutants react with oxygen and change into carbon dioxide and water. Second, the liquid is filtered to remove the particulate matter. Third, it is treated chemically with chlorine or ozone to kill any remaining harmful components such as bacteria.

Environmental, chemical and civil engineers work together to improve existing water treatment systems and design new ones to ensure that we have clean water both now and in the future. Today, let's imagine that we are engineers working for the Clean Water Environmental Engineering Company. The company has been asked to design a new water filtration system for a small community with a polluted water supply using limited materials. We are going to focus on the second step in the water treatment process, filtering. First, we are going to look at different types of filter material to determine which ones work well. Then each group in the company will design a filtering system to clean the polluted water. The best filtering system will be used in the small community.

Before the Activity

• Prepare the "polluted water" supply and let it ripen in a sunny spot for a day or two. Alternatively, do this as a class demonstration so that students know exactly what is in the water. If you have student create the "polluted water" supply, have them write down the ingredients and their sight and smell (not taste) observations about the solution as it changes.
• Place the aerator/mixer in one sample of "polluted water" and let it sit overnight before Part 1. You will probably need to aerate a large sample of water for a day or so before Part 2, depending on how many groups choose to use aerated water for their best filter. Note: Aeration, the process of adding air to water, is often part of the water purification process in order to help many harmful organic pollutants react with oxygen and change into non-threatening carbon dioxide and water.
• Be sure to mix the solution thoroughly before preparing the student samples.
• Prepare the 2-liter bottles: cut them in half horizontally. Place a square of mesh over the bottle opening and secure it with the rubber band. If you use cheese cloth, you will need to replace it before Part 2.
• Make copies of the Data Collection Worksheet , one per person.
• Make a transparency or large chart of the class data section for use in Part 1.
• Review the water cycle with the class. Pay special attention to where the water can be purified. See the following book for a great description: The Magic School Bus – Wet All Over: A Book about the Water Cycle by Joanna Cole and Pat Relf (New York, NY: Scholastic Books, Inc., 1996).

With the Students

• Divide the class into groups of three students each.
• Distribute a worksheet to each group.
• Remind the students that they are now working for the Clean Water Environmental Engineering Company and have been asked to design a new water filtration system for a small community with a polluted water supply. First, the company is going to look at different types of filter material to determine which ones work well. Then each group in the company will design a filtering system to clean up the polluted water.
• Give the following supplies to each group: a pre-cut 2-liter bottle, a ½-¾ cup (100-200 ml) sample of the "polluted water" in a beaker or cup, one type of "filter" (one group will not get a filter in order to test the mesh only), and a spoon.
• Ask each group to draw a picture of the "polluted water." Ask them to describe in words what it looks and smells like. Remind them to gently stir the solution and record their sight and smell observations on the worksheet. Remind students to never taste the solution.
• Ask students to come up with questions they think are important to answer throughout the activity about water filters (i.e., what makes a good filter?). Have them also write down on their worksheets their predictions for what they think their particular filter material will do.
• Ask students to set up their filters by placing the filter material into the inverted 2-liter bottle top, as shown in Figure 2. Note: Place the filter in the end of the bottle with the neck, so it functions like a funnel. Use the other half of the bottle as a stand. Prompt students to draw sketches of their setups on the worksheet.

• Ask students to gently stir the "polluted water" and then slowly pour it into the filter. Make sure the group with the filter paper is careful to not pour liquid above the top of the filter.
• Direct students to observe what happens during the filtration. Expect some filtrations to take longer than others. Remind students to record on their worksheets their observations and draw pictures of the filtered water.
• After all groups have collected data, share the results as a class by filling in the information on the transparency or chart made earlier. Have students record all team results in the class data section on the worksheets.
• As a class, look at the aerated sample. Discuss what aeration is and how it works (refer to the aeration explanation in the Before the Activity section).
• Ask students to work in their engineering design groups to design the best water filtration system given the filter material options and their choice of aerated or non-aerated water. Have them fill in the worksheet to record and explain their design choices. Permit them to use as many of the filtering materials as they want.
• Collect all supplies and dispose of used items properly. Rinse and save the 2-liter bottles Part 2.
• Have students sort into their Part 1 groups.
• Give each team a prepared 2-liter bottle, ½-¾ cup (100-200 ml) of the "polluted water" in a beaker or cup (aerated or non-aerated, whichever they chose) and a spoon.
• Distribute the filter materials as needed. Note: It helps if teams each send a designated "materials" person from to collect their supplies from a central classroom location.
• Ask students to fabricate their groups' water filter systems and draw pictures of them on their worksheets.
• For testing, direct students to gently stir the polluted water supply and then slowly pour an amount into the filter. For teams that used filter paper, remind them to be careful not to pour the liquid above the top of the filter.

• Alert students to carefully observe and record on their worksheets what happens during the filtration process. Note: Some filtration systems take longer than others to process the "polluted water," so students should not worry if their filtration systems takes longer than other systems. Also have teams draw pictures on their worksheets of the filtered water.
• Direct students to record their results and answer the worksheet discussion questions, comparing answers with team members.
• After all the groups are finished, label and line up the filtered samples. Ask each team to present its filter system to the class (aka Clean Water Environmental Engineering Company). Have students discuss similarities and differences in the filters.
• Conclude with a class vote and discussion about which water is the cleanest and why.

Engineering Presentations: Ask each team to present its filter system design to the class, explaining their logic. Examine the filtered solutions. Conclude with a class vote and discussion about which water is the cleanest and why.

Safety Issues

Remind students to only make sign and smell observations of the "polluted water" solution and never taste a solution, even if it looks "clean."

Have some paper towels, rags or sponges on hand in-case of spills.

Consider any student allergies before creating the dirty water sample.

Advise students to fold the filter paper so it fits into the bottle top and suggest they pre-wet the paper so that it sticks to the sides of the "funnel." An eyedropper and tap water are useful for pre-wetting the filter paper.

Remember to dispose of the waste from this experiment properly! Typically, the "polluted water" solution can be poured down the drain. But if any contaminating chemicals were used, dispose of it using responsible disposal methods.

Provide students with pH paper and a pH guide so they can determine the pH of the solution during different stages of the process: plain water, "polluted water" before treatment, after aeration, after filtering with one filter, and after using their final filter. Discuss how the different components in the solution affect the pH. How would the pH of the solution affect the rest of the environment? (Refer to pH table.)

Ask students to measure the volume before and after filtration. Younger students can describe it as more or less or use measuring spoons/cups. Older students can use labeled beakers or graduated cylinders.

Experiment with some simple chemical treatments. For example, add chlorine to a water sample as a class demo or with older students. Remember to wear protective equipment when handling chemicals!

Ask students: Does the order of the filter layers matter? Why or why not?

Direct students to filter their samples more than once, keeping a small sample after each filtration for comparison purposes. Does the water get (visually) cleaner on subsequent filtrations? Why or why not?

For younger students, conduct the activity as a demo with fewer filter choices. Demonstrate each filter type individually and then ask students to predict what will happen when both filter types are used together. Ask students to draw pictures of the results.

For older students, let the teams work more independently so more time is spent on the design portion of the project. Ask students to make their own suggestions for filter materials and other ways to treat the "polluted water." Have students bring in some materials from home to test as filters and have each team test its own items after you have modeled the filtration procedure.

Students learn about water quality testing and basic water treatment processes and technology options. Biological, physical and chemical treatment processes are addressed, as well as physical and biological water quality testing, including testing for bacteria such as E. coli.

Through the use of models and scientific investigation, students explore the causes of water pollution and its effects on the environment. Through the two associated activities, they investigate filtration and aeration processes that are used for removing pollutants from water.

30 Water Quality Technician Interview Questions and Answers

Common Water Quality Technician interview questions, how to answer them, and example answers from a certified career coach.

Ensuring the safety and quality of our most vital resource – water – is a critical endeavor, and as a Water Quality Technician, you play an essential role in this mission. Your expertise in monitoring, analyzing, and maintaining water systems will be invaluable to your potential employer, but first, you must successfully navigate through the interview process.

In order to help you make a strong impression during your upcoming interview, we’ve gathered a list of common Water Quality Technician interview questions that employers may ask to assess your knowledge, experience, and problem-solving abilities. These insights will not only aid you in preparing for the interview but also ensure that you demonstrate your competence in managing and protecting our precious water resources.

1. What is your experience with water sampling and testing procedures?

Hiring managers ask this question to assess your hands-on experience and familiarity with water quality analysis. As a water quality technician, you’ll be responsible for collecting and testing water samples to ensure compliance with regulations and maintain public health. Demonstrating your knowledge of sampling techniques, testing equipment, and analytical procedures will reassure employers that you are well-prepared to contribute effectively to their water quality monitoring efforts.

Example: “As a water quality technician with over three years of experience, I have been extensively involved in various water sampling and testing procedures. My work has primarily focused on monitoring surface water sources such as rivers, lakes, and reservoirs, as well as groundwater from wells.

I am proficient in collecting representative samples using appropriate techniques like grab sampling, composite sampling, and depth-integrated sampling. Additionally, I adhere to strict protocols for sample preservation, labeling, and transportation to ensure the integrity of the samples. In terms of testing, I have hands-on experience with several analytical methods, including titration, colorimetric analysis, and spectrophotometry, to determine parameters like pH, dissolved oxygen, turbidity, and nutrient concentrations.

My familiarity with these procedures allows me to efficiently assess water quality and contribute valuable data to support informed decision-making regarding water resource management and environmental protection.”

2. Can you explain the importance of pH levels in water quality analysis?

The question delves into your understanding of the technical aspects of water quality analysis. pH levels play a critical role in determining the water’s acidity or alkalinity, which can significantly impact the environment, aquatic life, and human health. Interviewers want to ensure you have the necessary knowledge to analyze water samples and make informed recommendations based on the findings.

Example: “Certainly, pH levels are a critical parameter in water quality analysis as they indicate the acidity or alkalinity of water. A neutral pH level is 7, while values below 7 represent acidic conditions and those above 7 signify alkaline conditions. The importance of monitoring pH levels lies in its impact on aquatic life, human health, and infrastructure.

Aquatic organisms have specific pH ranges within which they can thrive. Deviations from these optimal conditions can lead to stress, reduced reproduction rates, or even death for some species. This affects the overall balance and biodiversity of aquatic ecosystems. Additionally, extreme pH levels can cause harmful substances like heavy metals to become more soluble, posing risks to both aquatic life and humans consuming the water.

From an infrastructure perspective, highly acidic or alkaline water can corrode pipes and other equipment, leading to costly repairs and potential contamination issues. Therefore, maintaining appropriate pH levels is essential for ensuring safe drinking water, preserving aquatic ecosystems, and protecting infrastructure investments.”

3. Describe your knowledge of federal and state regulations related to water quality.

Being well-versed in regulatory standards is critical for water quality technicians. Ensuring the safety and quality of water for public consumption and environmental health requires adherence to specific guidelines. Interviewers ask this question to gauge your familiarity with these regulations and assess your ability to apply them in your daily work to maintain compliance and protect public health.

Example: “As a water quality technician, I have gained extensive knowledge of federal and state regulations related to water quality. At the federal level, I am well-versed in the Clean Water Act (CWA) and Safe Drinking Water Act (SDWA), which set standards for surface water and drinking water quality, respectively. These acts are enforced by the Environmental Protection Agency (EPA), which establishes guidelines for pollutant discharge limits, monitoring requirements, and reporting procedures.

At the state level, I am familiar with the specific regulations that apply to our region. For example, I understand the permitting process for discharging pollutants into state waters and the need to comply with Total Maximum Daily Loads (TMDLs) for impaired water bodies. Additionally, I stay up-to-date on any changes or updates to these regulations through regular training sessions and industry newsletters. This knowledge allows me to ensure that my work as a water quality technician is always compliant with both federal and state regulations, ultimately contributing to the protection of public health and the environment.”

4. Have you ever had to deal with a water contamination issue? If so, how did you handle it?

When it comes to water quality, safety is paramount. Employers want to know that you have experience dealing with contamination issues and that you can take appropriate action to resolve them. Your ability to handle these situations demonstrates your understanding of the importance of water quality, your problem-solving skills, and your commitment to public health and safety.

Example: “Yes, I have dealt with a water contamination issue in my previous role as a Water Quality Technician. We received reports of elevated levels of E. coli bacteria in one of the local water sources during routine testing. To handle this situation, we immediately informed the relevant authorities and initiated an investigation to identify the source of contamination.

We conducted additional tests on samples collected from various points along the water supply system to narrow down the affected area. Once we identified the likely source, which turned out to be a sewage leak near the water supply line, we collaborated with the maintenance team to address the issue promptly. Meanwhile, we advised residents in the affected area to use alternative water sources or boil their tap water until further notice.

IR-2024-137, May 9, 2024

WASHINGTON — The Internal Revenue Service reminds taxpayers that making certain energy efficient updates to their homes could qualify them for home energy credits.

The credit amounts and types of qualifying expenses were expanded by the Inflation Reduction Act of 2022. Taxpayers who make energy improvements to a residence may be eligible for home energy tax credits.

What taxpayers need to know

Taxpayers can claim the Energy Efficient Home Improvement Credit and the Residential Clean Energy Credit for the year the qualifying expenditures are made.

Homeowners who improve their primary residence will find the most opportunities to claim a credit for qualifying expenses. Renters may also be able to claim credits, as well as owners of second homes used as residences. Landlords cannot claim this credit.

IRS encourages taxpayers to review all requirements and qualifications at IRS.gov/homeenergy for energy efficient equipment prior to purchasing. Additional information is available on energy.gov , which compares the credit amounts for tax year 2022 and tax years 2023-2032.

Energy Efficient Home Improvement Credit

Taxpayers that make qualified energy-efficient improvements to their home after Jan. 1, 2023, may qualify for a tax credit up to $3,200.

As part of the Inflation Reduction Act, beginning Jan. 1, 2023, the credit equals 30% of certain qualified expenses:

• Exterior doors, windows and skylights.
• Insulation and air sealing materials or systems.
• Natural gas, propane or oil water heaters.
• Natural gas, propane or oil furnaces and hot water boilers.
• Heat pumps, water heaters, biomass stoves and boilers.
• Home energy audits of a main home.

The maximum credit that can be claimed each year is:

• $1,200 for energy property costs and certain energy efficient home improvements, with limits on doors ($250 per door and $500 total), windows ($600) and home energy audits ($150).
• $2,000 per year for qualified heat pumps, biomass stoves or biomass boilers.

The credit is nonrefundable which means taxpayers cannot get back more from the credit than what is owed in taxes and any excess credit cannot be carried to future tax years.

Residential Clean Energy Credit

Taxpayers who invest in energy improvements for their main home, including solar, wind, geothermal, fuel cells or battery storage, may qualify for an annual residential clean energy tax credit.

The Residential Clean Energy Credit equals 30% of the costs of new, qualified clean energy property for a home in the United States installed anytime from 2022 through 2032.

Qualified expenses include the costs of new, clean energy equipment including:

• Solar electric panels.
• Solar water heaters.
• Wind turbines.
• Geothermal heat pumps.
• Fuel cells.
• Battery storage technology (beginning in 2023).

Clean energy equipment must meet the following standards to qualify for the Residential Clean Energy Credit:

• Solar water heaters must be certified by the Solar Rating Certification Corporation, or a comparable entity endorsed by the applicable state.
• Geothermal heat pumps must meet Energy Star requirements in effect at the time of purchase.
• Battery storage technology must have a capacity of at least 3 kilowatt hours.

This credit has no annual or lifetime dollar limit except for fuel cell property. Taxpayers can claim this credit every year they install eligible property on or after Jan. 1, 2023, and before Jan. 1, 2033.

This is a nonrefundable credit, which means the credit amount received cannot exceed the amount owed in tax. Taxpayers can carry forward excess unused credit and apply it to any tax owed in future years.

Additional information is available at IRS.gov on qualifying residences and information for taxpayers who also use their home for a business.

When it is time to file a tax return, taxpayers can use Form 5695, Residential Energy Credits , to claim the credit. This credit must be claimed for the tax year when the property is installed, not just purchased.

Good recordkeeping

Taxpayers are encouraged to keep good records of purchases and expenses. This will assist in claiming the applicable credit during tax filing season.

Maui community mobilizes to protect water quality from runoff after Lahaina fires

Concerns have been high in Lahaina that the devastating wildfire would also harm the ocean. Here, members of a community-led group head out to collect water samples. Ryan Kellman/NPR hide caption

Debris from hundreds of buildings destroyed by wildfire in Lahaina, Maui still needs to be cleared. Piles of wreckage sit by the bright turquoise ocean, home to a coral reef where many residents swim, fish and surf.

The community is making a slow recovery from the August 2023 fire, which claimed more than 100 lives. And concerns have been high that the disaster could also damage another valued part of Lahaina: the ocean.

An urban fire of this magnitude has never been seen directly next to a sensitive marine ecosystem. A big question has been: is the water safe?

After the fires, a Maui community tries a novel approach to keep homes in local hands

"It's so hard to answer that," says Liz Yannell, program manager at Hui O Ka Wai Ola , a community-led group that measures water quality. "I'll get people that'll text me and say: my son wants to surf at this beach. Do you think that's safe tomorrow?"

Yannell's group is part of a coalition that mobilized in the wake of the fire to closely monitor the water quality off Lahaina. More than 2,000 buildings burned, including their appliances, plastics, car batteries and other potentially toxic materials. Those chemicals could runoff into the ocean, especially during heavy tropical rainstorms.

So far, the water contamination readings have been lower than expected, leading Hawaii's Department of Health to recently determine the water is safe for recreation. But scientists warn that the effects on a complex marine ecosystem like a coral reef will take years to figure out.

"There's so much that we don't see," says Andrea Kealoha, assistant professor of oceanography at the University of Hawaii at Manoa. "You don't really understand the impacts of anything in one year."

Sampling in the burn zone

Downtown Lahaina's waterfront was once the site of busy shops and residential homes. Every so often, the charred shell of a refrigerator is visible in the debris that remains, hinting at what once was there.

Among the blackened remnants of roofs and walls, there are mounds of silvery ash, even nine months later. After the fire, the Environmental Protection Agency sprayed a glue-like substance called Soiltac to stabilize the debris and prevent it from running off.

"Things are still in piles," says Christiane Keyhani, who works with Yannell at Hui O Ka Wai Ola. "So clearly it seems to have worked, the Soiltac. But if you step on it, it loses its effectiveness."

Every few weeks, a team from Hui O Ka Wai Ola, arrives in the burn zone to take water samples. Yannell and Keyhani put on masks and waders and head to where the waves are crashing. They collect water by dipping a long pole with a cup at the end into the ocean. The samples are then analyzed for the key indicators of water quality, like the pH, clarity, and oxygen levels.

"It's a clear day today in the ocean, but that doesn't mean there aren't concerns," Yannell says. "There were days, especially at the beginning, where it was so brown and turbid."

"This is looking better, which is a good thing," Keyhani says, holding a vial with one of the samples.

Christiane Keyhani checks water quality in downtown Lahaina. "It's still sad but I just love contributing in a positive way," she says. Ryan Kellman/NPR hide caption

Even after the group's lab burned down in Lahaina, staff and volunteers mobilized as quickly as they could to keep up their sampling efforts, aided by a FEMA grant . Their results are supplemented by data from a broad coalition also doing water sampling, including the University of Hawaii at Manoa, the Surfrider Foundation and state and federal agencies.

"There's so much to figure out and it takes all of us coming together to answer all of these questions," Yannell says.

For Keyhani, whose family goes back generations in Lahaina, the work is also a way to support the community in the face of grief.

"I feel incredibly blessed and grateful to be able to sample here," Keyhani says. "It heals for sure. At least I get to be closer to it and have that exposure therapy to the area because it meant everything to me and my family for generations."

So far, worst fears aren't playing out

Urban wildfires produce a broad array of contaminants, especially ones that burn at very high temperatures like in Lahaina. Heavy metals are present in urban infrastructure and in December, officials in Hawaii found Lahiana's ash contained lead and arsenic . The burning process also creates a broad range of "organic compounds'' - only some of which are well understood. One group, known as polycyclic aromatic hydrocarbons (PAHs), are known to be carcinogenic.

So far, water sampling shows higher levels of copper were found at the boat harbor, especially right after the fire. Copper is used in boat paint to prevent marine life from attaching and many boats burned during Lahaina's fire. Still, most contaminants have been lower than the guidelines set for human health , including PAHs.

"There is a sense of relief," Yannell says. "There's still more to figure out, but it's comforting in a way."

Hawaii's Department of Health recently determined that the water is safe for recreation. But scientists warn that the effects on a complex marine ecosystem like a coral reef will take years to figure out. Ryan Kellman/NPR hide caption

For the coral reef, the impacts are less well understood. Corals are highly sensitive animals, affected by cloudy water, pollution from fertilizers and wastewater, and too much sediment running off the land. Kealoha and others at the University of Hawaii have been monitoring the health of the reef off Lahaina post-fire.

"We also see high concentrations of things like zinc," Kealoha says. "And we don't really know what the impacts of zinc are to corals."

The water samples taken by Yannell and Keyhani are analyzed for the key indicators of water quality, like the pH, clarity, and oxygen levels. Ryan Kellman/NPR hide caption

Another research team at the University of Hawaii at Manoa is testing for more than 100 organic contaminants, since little is understood about how they could affect marine life at all levels, from tiny microbes to large fish.

"We don't know what's going to be a problem," says Craig Nelson, professor of oceanography at the University of Hawaii at Manoa. "So even if they're not on a list as having a threshold of being toxic to human health, it's still good for us to be able to track them and see how they're changing through time."

Other studies are underway to determine if toxins are accumulating in the fish people eat. Once the contaminants enter the food chain, they become concentrated over time as larger organisms eat smaller ones.

As the ash and debris in Lahaina are removed and the rebuilding process begins, runoff could still be a concern for the ocean. Researchers caution that it could take some time to determine how the coral reef may have been affected, since the effects may be hard to see. Just as the community of Lahaina is experiencing, the true impacts of the fire will take years to understand.

"This is going to be a really long process," says Sean Swift, a Phd student working on water testing at the University of Hawaii at Manoa, who also grew up on Maui. "Beaches are where people bring their babies and their kids and the reefs where people go fishing. And as soon as those things are threatened, I think you have a very strong emotional response."

Environment | Colorado’s demand for water is slated to surpass supplies by 2050. Did lawmakers do enough to address the crisis?

Bills aim to reduce “forever chemical” contamination, ban some turf, protect wetlands.

Nine major bills aim to reduce water use in cities, replace nixed federal protections of wetlands and minimize the amount of toxic “forever chemicals” leaching into water supplies. Gov. Jared Polis already has signed four of the bills into law, while four more await his signature and one will go to voters.

“It was a pretty big year for water under the dome,” said Bart Miller , the healthy rivers director at Western Resource Advocates, who has been monitoring Colorado water policy for 20 years. “It feels like the state is stepping up to take advantage of this moment of time — and not just sit idly by — as climate change makes our climate drier and our rivers shrink.”

But momentum must continue if Colorado is to avoid looming water shortages, lawmakers and advocates said. Critical conversations about paying farmers and others to use less water and making sure that conserved water is used thoughtfully must turn into policy, they said.

Colorado’s demand for water is expected to outpace its supply by 2050 as the population grows and climate change sucks moisture from streams and snow, according to state water experts . By that time, municipal and industrial water users every year could be short up to 240 billion gallons. Shortages already faced by Colorado’s agriculture sector will grow.

Lawmakers in recent years have responded to that crisis and momentum has grown around water policy at the Capitol, advocates said.

The biggest achievement this year, lawmakers and advocates said, was the passage of House Bill 1379 , which fills a gap in wetlands and stream protection created by a U.S. Supreme Court decision last year.

Colorado was the first state to pass legislation to address the decision, in which the court ruled that the federal Clean Water Act did not protect wetlands and temporary streams. The May 2023 ruling left more than half of Colorado’s waters without protections and regulations for construction activity.

Polis has not yet signed the bill, which would create a program in the Colorado Department of Public Health and Environment to regulate dredge and fill activities.

“It was critical to make this a priority for the legislature this session,” said House Speaker Julie McCluskie, one of the bill’s sponsors. “In a drought that has stressed our water resources in significant ways, there couldn’t be more urgency to make sure we’re protecting every waterway as best we can.”

Other major legislation

Among other water-related bills passed this session were two focused on quality: Senate Bill 81 , which has been signed into law, bans the sale of some consumer products with intentionally added PFAS chemicals — like cookware and ski wax — beginning in 2026 and another class of products in 2028, in part to reduce how much of the chemicals reach waterways. And Senate Bill 37 (not yet signed into law) orders a study of ways to use “green infrastructure” to improve water quality.

Voters will be asked in November to decide a ballot measure referred by House Bill 1436 allowing the state to keep more sports betting tax revenue for state water projects. The measure would remove the cap on the amount of money that goes for those projects.

Currently, any tax revenue above $29 million each year is returned to the betting companies.

Several other bills are targeted at conservation in various ways:

• Senate Bill 197 (not yet signed into law), would implement recommendations from the Colorado River Drought Task Force convened last year. That includes making it easier for tribal nations to apply for state water grants and allowing people who hold agricultural water rights to loan them to the state water conservation board to boost flows.
• Senate Bill 5 (signed into law), bans the installation of new non-functional turf and artificial turf on commercial, industrial, government and HOA-owned property beginning in 2026.
• House Bill 1362 (signed into law), allows the installation of graywater systems in new construction statewide. Graywater systems collect water after its first use and reuse it for a variety of purposes, like flushing toilets or watering plants.
• House Bill 1435 (not yet signed), would allocate $56 million to water projects through state agencies, including water supply forecasting and turf replacement. The bill also includes $20 million for the purchase of the Shoshone power plant water rights .
• Senate Bill 148 (signed into law), allows stormwater facilities to harvest and store rain running off hard surfaces like asphalt.

There will likely be further tweaks to the dredge-and-fill legislation for wetlands and seasonal streams as the program is implemented, said Stu Gillespie , a senior attorney at environmental conservation law firm Earthjustice. More stringent protections might be needed, he said, as the nation’s wetlands were being eradicated even before the Supreme Court decision.

Making progress, with more needed

Overall, the water-related legislation passed this session was a good step forward, said Sen. Dylan Roberts, an Avon Democrat who sponsored several of the bills. The turf bill alone will save millions of gallons of water since nearly half of municipal water is used to water lawns.

Lawmakers need to continue to pursue innovative solutions for the state’s most critical resource, he said, even if it’s not the flashiest policy topic.

Lawmakers in coming years should consider the creation of a statewide demand management program , which would pay water users to temporarily reduce the amount of water they consume, said Josh Kuhn , water campaign manager for Conservation Colorado.

Roberts remains disappointed that the Colorado River Drought Task Force , which convened last year, didn’t make recommendations on such a program, but he hopes conversations will continue.

“I’ve always been of the mindset that there’s no harm in preparing now and getting things ready for when we need them,” Roberts said.

Water policy is complicated and can take years to develop, said Zane Kessler , director of government relations at the Colorado River District.

Everyone involved in Colorado water policy knows that more needs to be done in the face of a hotter, drier future, he said.

The 2024 legislative session was an attempt to rise to the occasion, Kessler said, and the results show that lawmakers and advocates can make progress through conversation and compromise.

“Sometimes these big hairy policy issues require time and conversation,” he said. “It’s impossible to go to a water conference without someone bringing up the adage: Whiskey is for drinking and water is for fighting about. I just don’t think that’s true.”

This time of year, endangered smalltooth sawfish are usually giving birth to their young in the waters at Florida’s southern tip. But this spring, people are watching, horrified, as dozens of sawfish thrash helplessly in circles before they die.

Marine experts are baffled, and they’ve raced to South Florida to try to pinpoint the cause and rescue ailing fish. They have tested the water and samples from dead fish and ruled out water temperature, red tide and other variables. Experts interviewed by the Tampa Bay Times and other media outlets say current evidence points to a type of toxic algae.

And it’s not just sawfish, which are a species of ray with unusually long, toothy snouts. People fishing and boating around the Florida Keys, southwest Florida and Everglades National Park’s coastal areas have reported over 50 different marine species acting erratically and then dying, including sharks, Goliath grouper, snook, snapper, sting rays, stone crabs and pinfish.

We are witnessing another wakeup call about Florida’s poor water quality. On South Florida’s reefs, corals are bleaching and dying from disease. Hundreds of manatees starved to death in 2021 when algae outbreaks — fueled by fertilizer, sewage and agricultural waste — shaded out the seagrass they eat.

Year after year, we hear the ridiculous arguments from polluter-friendly politicians that Floridians are somehow standing in the way of progress by asking for commonsense environmental protections. We hear false assumptions about why we don’t need to properly conserve wetlands and mangroves; and most of all, that it would be too harsh to set more effective limits on the agricultural waste, sewage and fertilizer that are fouling our public waters, spewing dead fish on our beaches and chasing away swimmers.

When the unprecedented 2021 manatee die-off happened, Earthjustice filed suit against the U.S. Environmental Protection Agency on behalf of the Center for Biological Diversity, Save the Manatee Club and Defenders of Wildlife. Our lawsuit, which focuses on Florida’s water quality standards, is ongoing.

The background: Years ago, when EPA approved Florida’s water quality standards, federal wildlife agencies had to assert, under the law, that the state’s measures would protect wildlife listed under the Endangered Species Act. But the hundreds of dead manatees in the Indian River Lagoon are proof that Florida’s water quality standards aren’t working. The lawsuit asks the court to require EPA to reinitiate consultation with the U.S. Fish and Wildlife Service and National Marine Fisheries Service to reassess its approval of Florida’s water quality standards for the Indian River Lagoon.

It is critical to remember that the United States has laws to protect clean water and the species that depend on those waters. The smalltooth sawfish, in fact, was the first marine animal to be added to the Endangered Species Act list in 2003. Southern Florida is their last stand; they used to roam as far north as North Carolina and Texas, and south to Brazil.

6 ways to use Microsoft Copilot for end-of-school-year tasks

May 14, 2024.

By Microsoft Education Team

Share this article

The end of the school year is a hectic time for educators everywhere. Between reviewing content, completing assessments, and maintaining classroom management, it’s easy to feel the pressure of too many responsibilities and not enough time to accomplish everything.

Whether closing out the academic year in the northern hemisphere or preparing for the next one in the southern hemisphere, Microsoft Copilot offers innovative and efficient ways to complete many of the tasks that occupy these transitional times of year. From drafting student feedback to composing newsletters and offering planning suggestions for events, Copilot adapts to whatever task it’s asked. To get started, all you need is a basic understanding of how to access and use Copilot.

Start using Copilot for your end-of-school-year tasks

You can learn how to use Copilot by visiting Meet your AI assistant for education: Microsoft Copilot .

When you’re ready to get started, go to copilot.microsoft.com or download the iOS or Android mobile app.

Writing prompts for the end of the school year

Prompting Copilot to generate content requires practice. Including specific information in your prompt helps produce more relevant responses.

An effective Copilot prompt:

• Asks the tool to take on a role called a persona .
• Provides an objective  that tells the tool what to do or produce.
• Defines the audience  who will be using whatever Copilot generates.
• Includes context  that gives the tool background information.
• Sets boundaries  that limit or constrain responses.

Elements of a Good Prompt infographic which includes tips for writing prompts that produce more relevant responses.

Throughout this post, you’ll find sample prompts that include these components. We recommend borrowing inspiration from them and adjusting to make them fit your own classroom, or you can copy and paste the examples without modifications if you are just beginning.

Now let’s learn how Copilot can help you complete six common end-of-school-year tasks.

1. Craft student feedback at the end of the school year

Copilot can help you write end-of-school-year feedback in a style and tone that all students can understand. Simply craft a prompt that includes the subject area and details about the feedback you want to provide, and Copilot can draft a constructive, supportive statement written specifically for students. For example:

You are a fourth-grade teacher who is writing feedback on a student’s current reading skills. The student uses details to explain what text means but is unable to draw inferences in fiction. The student can identify in-text examples that illustrate a given theme but is unable to independently produce a theme without guidance. Write a short statement that explains this feedback to a student. Include a description about why using details is important and 1-2 ways to develop this skill. The paragraph should be written with plain text so that a fourth-grade student will understand.

You can always refine your prompt if the response is not what you expected. Simply include something like, “Re-write this feedback in Spanish” without selecting New topic , and Copilot will continue where you left off. Give it a try.

2. Write end-of-school-year reflections

Educators often write end-of-school-year newsletters for families, update class blogs with a final post, and draft reflections on school year goals. Copilot can assist with all these tasks and can help you create personalized, engaging visuals for your content. For example, you can use the following prompt to produce a summer newsletter for families.

You are the science department leader for a middle school in New York City. Draft a summer newsletter for families that includes an introduction that talks about the past year and 5 sections: Science Books for Young Adults, Science at Home, Science Summer Camps, Science Events in NYC, and NY Science Museums. Only include information that can be linked to a website to learn more. The newsletter should be written in plain text using an informal tone.

You can also share your experiences, memorable moments, and insights from the school year and Copilot will help you find creative ways to share this information with colleagues, families, and students.

3. Organize classroom materials at the end of the school year

The last few weeks of a school year includes packing up classrooms for the summer, collecting books and devices, and organizing materials for the next year. Copilot can create checklists or reminders for end-of-school-year tasks like these and offer suggestions that you might not even consider. For example:

You are a high school media specialist who checks out technology to administrators and educators. Write a checklist of the 3 most important things to do before returning each of the following devices: document camera, tablet, digital projector, games, and wires. Make each device a section heading and use bulleted lists for the content. Write the checklists so that the content is easily understood by people with varying levels of technological expertise.

Another way to use Copilot when you are organizing classroom materials is to ask for suggestions for efficient ways to declutter and prepare your classroom for the next school year.

4. Plan an end-of-school-year celebration

Many schools celebrate major milestones like the start of summer or moving from lower grades to higher grades with a party or ceremony. Copilot can be your personal planner and assist with brainstorming ideas for end-of-school-year events, awards ceremonies, or virtual gatherings. It can even suggest ways to be more inclusive in areas you might not have considered, like food options in the prompt below.

You are a guidance counselor in charge of helping rising eighth-grade students transition from middle school to high school. Draft a letter to middle school teachers that shares the biggest differences between middle school and high school. Include paragraphs on class schedules, touring the high school, meeting educators, extracurricular activities, and summer reading books. The letter should be written in a formal, conversational tone.

Whether you are creating invitations, planning activities, or drafting speeches, Copilot can be your creative collaborator.

5. Develop transition materials at the end of the school year

When students enter elementary school or move to middle or high school, everyone involved in the transition needs to know how to prepare for this change. Students need to know what to expect, families need to know how to support their children, and current educators need to provide relevant information. Copilot can help create transition materials so that everyone stays informed using a prompt like this example:

You can also use Copilot to write welcome letters, tips for success, or information about what to expect in the upcoming year.

6. Streamline parent communication at the end of the school year

Copilot can help you create templates for parent-teacher conferences at the end of the school year, as well as student progress updates, and letters to families. For example, you can ask Copilot to create a message to families about signing up for conferences with the following prompt.

You are a high school math teacher who teaches introductory algebra. Write a letter to families about parent-teacher conferences. Include an introductory paragraph that thanks families for their ongoing support and paragraphs about what will happen during the conferences, why conferences are important, who should attend, and how to prepare for the meeting. Conclude the letter with a paragraph about how to sign up for a conference slot. Write the letter using an approachable, informal tone.
