The Water Cycle

by Mr. Rojas

How much water covers Earth’s surface?

Almost 70% ( 7/10 )

Earth’s surface is made up of both land and water. Why is Earth often called the “water planet”?

Earth’s Water

Fresh Water

Frozen in Ice Caps

& Glaciers (a little over

2% of all of Earth’s water)

Underground

(less than 1% of all

of Earth’s water)

In Air, Soil, Rivers,

& Freshwater Lakes

(very small amount)

Fact: Drinking water is also called freshwater

About 97% of Earth’s water supply is salt water that is found in oceans and seas. Only 3% is fresh water that humans and other living things need to survive.

Glaciers & Ice Caps

One major problem is that much of Earth’s fresh water supply is not available for everyday use. About two-thirds (2/3) of this fresh- water is “locked away” as ice in glaciers and polar ice caps. That leaves less than one percent of Earth’s total water supply as fresh water that people can drink, cook and grow food.

What is the Water Cycle?

The water cycle is: The transferring of water from the Earth’s surface to the atmosphere and back, in a never-ending cycle.

It is also known as the “hydrologic cycle”.

But one thing about water doesn’t change. There is only a certain amount of water on Earth—no more, no less—and that total doesn’t change.

Water Cycle Animated Online

http://earthguide.ucsd.edu/earthguide/diagrams/watercycle/index.html

Evaporation

• Evaporation happens when liquid water is changed to water vapor (invisible gas) thanks to the power of the sun's heat , and rises up towards the sky.
• Water evaporates from the oceans (mainly), lakes, rivers, soil and plants.

Condensation

Condensation is the change of water vapor into liquid drops which come together to form clouds. This happens high up in the atmosphere, where the air is cooler.

How do Clouds Form?

• Clouds form when evaporated water (water vapor) rises to higher altitudes where the air is cooler. As this cooling occurs, the water vapor condenses (comes together) from a vapor to a liquid. When many tiny water droplets form near each other, a cloud is form.
• Conditions have to be just right for clouds to form. Nature needs tiny droplets of water, something for the droplets to cling to (particles like dust, salt, or smoke) and the right temperature (cooler).

Key Ingredients

for Clouds to Form:

Lots of water vapor

temperatures

something for the

droplets to cling

to (i.e: dust particles)

Precipitation

Online: How Precipitation Works

• Precipitation is any form of water that falls from clouds. Precipitation comes in four forms: rain, snow, sleet, or hail. What decides which form it will come down as is dependent on the temperature and even on wind conditions.
• When cloud drops come together, they start to get heavy, so gravity returns the water to the Earth’s surface as precipitation – usually rain.
• Precipitation that sinks into the ground is called groundwater .
• Precipitation that runs off Earth’s surface into rivers, lakes, and oceans is called runoff .

Precipitation falls in four forms:

rain, snow, sleet (frozen rain), or hail.

What Makes Oceans Salty?

• Most of the salts and other substances in the ocean come from the land.
• As rivers, streams, and runoff flow over the land, they slowly break down the rocks that make it up.
• Over time, flowing water carries substances (such as minerals) from the rocks to the oceans where these collect. This is what makes oceans salty.

How do Living Things Give Water �Back to their Environment?

Animals return water to the environment:

• as they give off water vapor when they exhale (respiration)
• as they sweat (perspiration)
• as they urinate (urination)

Plants return water to the environment:

• as they give off water, a waste-product of photosynthesis, through their stomata (transpiration)

How does water change through the water cycle as it goes from place to place?

• It changes from liquid, to gas (water vapor), and back to liquid (as in rain) again.
• But sometimes the water vapor may change to a solid instead of a liquid (as in snow, sleet, or hail), depending on the temperature.

Water numbers

Some of water's physical properties:

• Weight: 62.416 pounds/cubic foot at 32°F; 1,000 kilograms/cubic meter
• Weight: 61.998 pounds/cubic foot at 100°F; 993 kilograms/cubic meter
• Weight: 8.33 pounds/gallon; 1 kilogram/liter
• Density: 1 gram/cubic centimeter (cc) at 39.2°F, 0.95865 gram/cc at 212°F

Some water volume comparisons:

• 1 gallon = 4 quarts = 8 pints = 128 fluid ounces = 3.7854 liters
• 1 liter = 0.2642 gallons = 1.0568 quart
• 1 million gallons = 3.069 acre-feet = 133,685.64 cubic feet

Flow rates:

• 1 cubic foot/second (cfs) = 449 gallons/minute = 0.646 million gallons/day = 1.98 acre-feet/day

Water facts

Water is called the " universal solvent " because it dissolves more substances than any other liquid. This means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Pure water has a neutral pH of 7, which is neither acidic (less than 7) nor basic (greater than 7).

The water molecule is highly cohesive   — it is very sticky, meaning water molecules stick to each other. Water is the most cohesive among the non-metallic liquids.

Water molecules are also adhesive  in that they stick to other surfaces. Both cohesion and adhesion make water molecules very sticky!

Pure water, which you won't ever find in the natural environment, does not conduct electricity . Water becomes a conductor once it starts dissolving substances around it.

Water has a high heat index —it absorbs a lot of heat before it begins to get hot. This is why water is valuable to industries and in your car's radiator as a coolant. The high heat index of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans.

Water has a very high surface tension . In other words, water is sticky and elastic, and tends to clump together in drops rather than spread out in a thin film, like rubbing alcohol. Surface tension is responsible for capillary action , which allows water (and its dissolved substances) to move through the roots of plants and through the tiny blood vessels in our bodies.

Air pressure affects the boiling point of water, which is why it takes longer to boil an egg at Denver, Colorado than at the beach. The higher the altitude, the lower the air pressure, the lower the boiling point of water, and thus, the longer time to hard-boil an egg. At sea level water boils at 212°F (100°C), while at 5,000 feet, water boils at 202.9°F (94.9 °C).

• Revised Lead and Copper Rule: Testing at schools and child-care facilities As schools begin returning to session, water utilities across the United States are busy preparing for fall 2024 when the U.S. Environmental Protection Agency’s Lead and Copper Rule Revisions (LCRR) will require a new level of communication and cooperation with schools and child-care providers. School districts can be great partners, providing utilities a way to tell their water story through public education and inspiring a new generation who may one day be water operators. But schools operate very differently than many government agencies – from their funding sources to staffing and overall culture. Getting ready to be LCRR compliant means water systems must pay special attention to the needs of school districts and how to best collaborate with them.  Water utilities are required to provide schools and child-care facilities with a copy of EPA’s Training, Testing and Taking Action (3T’s) for Reducing Lead in Drinking Water in Schools and Child Care Facilities, as part of the LCRR sampling process. Utilities must sample at least 20% of elementary schools and 20% of child-care facilities in their service areas for the following five ...
• News reports on lead in Detroit schools Water utilities should be aware of current news reports on a decision to shut off access to drinking water in Detroit schools. With the start of the new school year, these stories may prompt questions from media and customers in other communities about lead levels in schools. Water utilities should be prepared to express their commitment to protecting children from lead in drinking water, including describing how they communicate with schools and daycare facilities in their service areas. Key points to elevate include: •    Our first priority as water providers is the protection of public health. •    Lead is typically not found in the water leaving our treatment or traveling through water mains. However, it may be present in school plumbing, as well as drinking water bubblers or coolers. •    Our utility takes the following steps to assist schools in understanding and managing lead risks from drinking water [if applicable, provide examples of letters to school districts, sampling guidance, etc.] •    EPA developed a guidance document titled 3Ts (Training, Testing, Telling) for Reducing Lead in Drinking Water in Schools, which outlines ...
• Operator-in-training courses taught in high schools By Ann Espinola Darrell King has a big job. He’s head of the water utility in Evanston, Ill. where he oversees nearly three dozen employees and a treatment plant serving more than 400,000 customers. But he spends every Saturday morning in a North Chicago classroom, where he teaches high school students how to become water treatment operators.   The program is one man’s way of forestalling the impending water sector labor shortage created by Baby Boomer retirements, and giving back to the community where he grew up. It is also among a handful of high school operator-in-training programs throughout the United States. In Texas, for example, water utilities in Irving and Arlington are working with their local school districts to prepare graduating seniors to pass water and wastewater licensing exams. In Portland, Ct., the city, utility and local school district partnered seven years ago to offer an operator course at the high school, but the program was discontinued two years ago during a change in leadership at the utility. The city hopes to start it up again in January.  The Irving program began ...

And it’s a job most people don’t know much about. They think water goes down the drain or the toilet and that’s the end of it.” The Florida Section of American Water Works Association (FSAWWA) received the 2020 Section Education Award for its High School Academy Program. The need to hire well-trained operators to replace retiring employees is urgent — in AWWA’s 2020 State of the Water Industry, respondents ranked “aging workforce/anticipated retirements” as one of the top 10 challenges facing the water industry. “If we can find people who have already taken courses, taken exams, people who know what they’re getting ...
• Kids safe to sip from school faucets, thanks to CECorps and AWWA section The school serves students in kindergarten through eighth grade and hosts community activities. The water system in the building had intermittently experienced high concentrations of lead in its water supply, which comes from a single well. Samples from specific faucets had lead levels of 40 parts per billion (ppb), exceeding the State of Washington’s lead action level of 15 ppb (90th percentile). A CECorps team of PNWS-AWWA volunteers, led by Lynn Williams Stephens (pictured right) and John Roth (pictured below), visited the site in the fall of 2016 and initiated measures to correct the situation. “We wanted a project that helped a low-income community address a water quality problem and the State of Washington Department of Health referred us to this school,” said Stephens, who works at Brown & Caldwell in Seattle. “I can’t think of a more important place than a school to try to reduce lead exposure. This also opened my eyes to the small-scale water systems I didn’t even know existed.” Volunteers in action The school did not have a full-time water operator and relied on contractors.

Why Is Water So Important? Here’s What You Need to Know

How water works in your body, how much water do you need, how to stay hydrated.

Water is a major component of your body, accounting for 50–60% of your total weight. It is vital for many important body functions, from flushing out waste to lubricating your joints.

Your body constantly loses water throughout the day through urinating, sweating, and breathing. You should consume enough water from foods and beverages daily to prevent dehydration .

This article covers research-backed reasons why your body needs water and how much you need each day.

Klaus Vedfelt / Getty Images

All body cells, organs, and tissues require water to function. Generally, a person can only survive without water for a few days.  

It Maintains a Normal Body Temperature

Water regulates our internal temperature by distributing heat throughout the body and cooling it through perspiration (sweat).

When the body becomes too hot, it loses water through sweat . The evaporation of sweat from the skin cools the body, keeping its temperature within a normal range.

If a person becomes dehydrated, they can't produce enough sweat to cool their body. This can cause the body's temperature to reach dangerous levels, leading to heat stroke .

Avoid dehydration by drinking plenty of water if you're working outside or sweating more than usual.

It Protects Your Joints, Spinal Cord, and Other Tissues

Water acts as a lubricant in the mouth (through saliva ) and the eyes (through tears) to help prevent dryness. It's necessary to produce synovial fluid , which lubricates, cushions, and protects the joints.

Water also helps protect the spinal cord and prevents injuries by increasing tissue flexibility and elasticity.

It Transports Nutrients and Gets Rid of Waste

As a major component of blood, water helps transport nutrients and oxygen to cells throughout the body. Water also helps carry waste from the body for excretion through perspiration, urination, and bowel movements.

The kidneys need water to effectively filter waste from the blood and flush it from the body as urine. Staying adequately hydrated helps prevent kidney stones and urinary tract infections (UTIs) , which can harm the kidneys.

Prevents Dehydration

Drinking water daily can help prevent dehydration, a condition that occurs when you lose more fluids than you absorb.

Early signs of dehydration include:

• Feeling thirsty
• Dark-colored urine
• Urinating less than usual

Because water is involved in so many body functions, dehydration can eventually cause life-threatening symptoms, including:

• Rapid breathing
• Rapid heartbeat
• Inability to urinate

People who exercise in the heat, work outdoors, or have certain health conditions that cause them to urinate or sweat more than usual are at a greater risk of dehydration.

It Aids Digestion

Your saliva is primarily made up of water. Saliva is a digestive juice that moistens food, allowing it to move easily through the esophagus into your stomach. Saliva also contains enzymes that help break down starches in food.

As the digestive process continues, water helps break down food, allowing your body to absorb nutrients. Water also makes bowel movements easier.

It Protects Against Chronic Illness and Boosts Longevity

Adequate hydration is linked to healthy aging and longevity. One potential reason for this is that decreased water intake can lead to higher sodium concentrations in the blood, which raises the risk of chronic disease.

Studies suggest that adults who stay hydrated are healthier and less likely to develop chronic diseases, including heart and lung disease . Well-hydrated adults also seem to live longer than adults who don't consume enough fluids.

It Improves Mood and Cognitive Function

Dehydration may cause fatigue and confusion and may be linked to symptoms of anger and depression. In a small study, it was linked to poor cognitive function, potentially affecting attention span and working memory.

One study of young adults looked at the effects of water on cognitive performance and mood after 12 hours of water restriction. Researchers found that 200 milliliters of water improved thirst, anger, fatigue, and overall mood. However, 500 milliliters was optimal, improving mood and cognitive performance.

The amount of water you need depends on several factors, including age, sex, activity level, and health status.

For healthy individuals, the adequate daily water intake is around 11.5 cups for women and about 15.5 cups for men. This includes fluids consumed from all foods and beverages.

Experts estimate that most people get around 20% of their daily water intake from food. This means women should drink about 9 cups of fluid daily, while men should aim for 13 cups to maintain adequate hydration.

People who live in warmer climates, are more physically active, or are experiencing an illness that causes fever and/or diarrhea or vomiting have increased fluid needs.

One easy way to see if you are properly hydrated is to check the color of your urine. If you are drinking enough water, your urine will be pale yellow. If it is dark, you may need to increase your consumption.

Individuals with heart failure or kidney disease may need to limit their fluid intake.

Can You Drink Too Much Water?

Drinking too much water can lead to water intoxication or overhydration, which occurs when the kidneys cannot flush out excess water. This can cause a medical emergency due to decreased sodium concentrations in the blood ( hyponatremia ). To avoid water intoxication, do not drink more than 48 ounces, or six cups, per hour.

If you find it challenging to stay hydrated, here are some helpful tips to keep in mind:

• Keep a reusable water bottle with you and refill it throughout the day
• Choose water or sparkling water instead of sugary beverages
• When you feel thirsty, drink water
• Change things up by squeezing fresh lemon or lime into your water or adding a few berries or cucumber slices
• Snack on water-rich fruits and vegetables , including watermelon, cantaloupe, lettuce, and celery, throughout the day
• Keep track of your water intake by using a water tracker app
• Drink water with all meals

Water is vital for your health. It is necessary for temperature regulation, digestion, nutrient absorption, and body waste removal. Drinking water daily can prevent dehydration, a condition that can cause mood and memory problems, constipation, and kidney stones.

People who work in high temperatures, exercise at high intensities, or are sick are at a greater risk of dehydration. Talk to a healthcare provider or registered dietitian to determine the right amount of water for you.

The Water Cycle • Describes the movement of water on, in, and above the earth • Water is always changing and moving from one place to another • This cycle is made up of a few main parts: • Precipitation • Infiltration • Runoff • Transpiration • Evaporation • Water Vapor • Condensation • Collection

What is the water cycle? • The repeating change of water on the Earth creates a cycle • As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapor) • Ice can change to become water or water vapor • Water can change to become ice or water vapor • Water vapor can change to become ice or water.

Precipitation • Happens when the temperature and the atmospheric pressure are right • The small droplets of water in clouds form larger droplets and precipitation occurs. The raindrops fall to earth. • Occurs when so much water has condensed that the air cannot hold it anymore • The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow • Click the speaker below to hear rain falling

Forms of Precipitation • Rain: Sleet: • Snow: Hail:

Infiltration • Important process where • rain water soaks into the • ground, through the soil and underlying rock layers • The flow of water from the • ground surface into the ground • Once infiltrated, the water • becomes soil moisture or • groundwater

Groundwater Flow • Movement of water underground is called groundwater flow • Groundwater slowly moves through the spaces and cracks between the soil particles on its journey to lower elevations

Runoff • The movement of land water to the oceans, mainly in the form of rivers, lakes, and streams • Consists of precipitation that neither evaporates, transpires nor penetrates the surface to become groundwater • Excess runoff can lead to flooding, which occurs when there is too much precipitation

Transpiration • Process that happens through plants • As plants absorb water from the soil, the water moves from the roots through the stems to the leaves • Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air.

Evaporation • The process where a liquid, in this case water, changes from its liquid state to a gaseous state. • The sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. • The water vapor or steam then leaves the river, lake, or ocean and goes into the air.

Water Vapor • Water in its gaseous state-instead of liquid or solid (ice) • Totally invisible • Extremely important to the weather and climate • Without out it, there would be no clouds or rain or snow • All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow

Condensation • Formation of liquid drops from water vapor • Occurs when a parcel of rising air expands and cools • Responsible for the formation of clouds • These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle

Collection • When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land • When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink. • It may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again.

How Do These Changes Happen? • Adding or subtracting heat makes the cycle work. • If heat is added to ice, it melts. If heat is added to water, it evaporates. • Evaporation turns liquid water into a gas called water vapor. • If heat is taken away from water vapor, it condenses. • Condensation turns water vapor into a liquid. • If heat is taken away from liquid water, it freezes to become ice.

Why the water cycle is important • Humans use water for drinking, respiration, perspiration, and elimination of wastes are all part of this cycle • Large amounts of water are needed for most economic activities: agriculture and mining, food processing, manufacturing • Lakes and rivers provide towns and cities with a means of discharging wastes

Why the Water Cycle is Important… Continued • Generation of electricity from thermal power plants • Waterways provide transportation • Recreational activities • Some people view the rivers and large lakes of this country as a part of their own identity • AND MUCH MORE!!!

The Summary of the Hydrologic Cycle • The water cycle is called the hydrologic cycle. In the hydrologic cycle, water from oceans, lakes, swamps, rivers, plants, and even you, can turn into water vapor. • Water vapor condenses into millions of tiny droplets that form clouds. • Clouds lose their water as rain or snow, which is called precipitation. • Precipitation is either absorbed into the ground or runs off into rivers. • Water that was absorbed into the ground is taken up by plants. • Plants lose water from their surfaces as vapor back into the atmosphere. • Water that runs off into rivers flows into ponds, lakes, or oceans where it evaporates back into the atmosphere. • The cycle continues.

Now it’s your turn! Lets label the Water Cycle together! Condensation Evaporation Precipitation Runoff Infiltration Groundwater flow

Presentation about water

Last updated Saturday , 16-03-2024 on 10:55 am

Presentation about water , contains all the information about water,  the causes of water pollution and you will also find here how to save water. All this information will be found here in  presentation about water, in addition to the introduction and conclusion that you can use in the presentation.

Introduction;

Hello, my name is(your name). I’ll make a presentation about  the importance of water  today ,and I’ll show you some pictures. I hope  you’ll get benefit with the subject. If you have any question I’ll be happy to answer it after I finish.

The importance of water

What distinguishes the earth from other planets and other celestial bodies is its competence in the element of life which is water. God made of water everything living.

Water represents more than two-thirds of the earth’s surface compared to land. The water wealth is distributed on the surface of the earth in rivers, seas and oceans.

Water is of great importance in life as you can hardly find anything that does not need water, and I will try to summarize some points that show the importance of water in all aspects of life and its details.

Water is the element of life, it is a component of the composition of all creatures, which is essential in its permanence and life, and enters the composition of cells and tissues, and a large part of the mass of the body is of water.

Water is the main source of drinking as no one can live without drinking water, which protects our bodies from drought and thirst.

Water enters industries of all kinds. Food industries need water mainly, solid and heavy industry, aircraft and automobile industry, all of which require water either for manufacturing itself or for continuous cooling in machinery and manufacturing equipment.

Even manufactured materials need water. Cars, for example, need water for continuous cooling on the car’s engine.

Methods of water conservation;

Water consumption is undoubtedly the first way to save water wealth from the depletion it . It preserves the water grace in our hands. One way to rationalize water consumption is to wash your car for example or rinse with a bucket instead of a water hose.

Protecting the water from pollution that may affect it. This is done by enacting legislation and activating laws that deter the aggressors against water wealth such as dumping waste in water reservoirs used for local drinking, pollution of marine beaches by citizens or large companies operating in seaports, or Factories that dispose of their waste in water bodies.

The establishment of dams and large reservoirs that save rainwater and work to store it to serve as a strategic reserve for the state as well as works to maintain water wealth and provide them for people and public uses when needed.

Conclusion;

Thank you for listening. I hope you have benefited from the topic. If you have any questions you would like to ask, I would be happy to answer them all.

We have already provided you with a presentation about water, and you can read more through the following section:

Conference Wrap Up: Poster Presentations, Lightning Talk Winners, and More

Over 300 participants attended the 2024 WRRI Annual Conference, which took place in Raleigh on March 20 and 21 and featured engaging talks and presentations on water-related issues from researchers and practitioners across the state.

The event included 37 poster presentations, 16 lightning talks, and additional oral presentations and panel discussions over 6 concurrent sessions. WRRI would like to thank all attendees and speakers for their participation and their insightful presentations and posters, without which the conference would not have been possible!

Oral presentations covered topics including nutrient management, stream assessment and erosion, harmful algal blooms, and water policy. View the online conference program to learn more about these engaging and timely presentations!

Opening panel emphasizes community collaboration

On the first day of the conference, our opening panel focused on the ways in which collaborative community based research can be mutually beneficial to both researchers and the communities they’re partnering with. Panelists included hydrologist and community-engaged scholar Ryan Emanuel, chairperson of the Chowan Edenton Environmental Group Colleen Karl, and Neuse Riverkeeper Samantha Krop.

Panelists spoke of the synergistic opportunities to work alongside community partners, and the importance of community outreach and engagement as an integral and complementary part of scientific research.

Emanuel, an environmental scientist and a member of the Lumbee tribe, described being frustrated by the lack of intersection between his research and his community. He detailed how he changed his approach to both scientific research and community outreach in order to bring the two closer together, with a focus on promoting environmental justice and Indigenous rights.

Colleen Karl, chairperson of the Chowan Edenton Environmental Group, emphasized the benefits of close collaboration between scientists and community members affected by the recurring seasonal algal blooms on the Chowan River and Albemarle Sound. She highlighted the ways in which citizen science can help to mobilize community members to collect water samples and analyze algal cells, ultimately furthering scientific understanding of how and why these harmful algal blooms form.

Sound Rivers’ Samantha Krop echoed the sentiments of the other two presenters in her exploration of her work as a riverkeeper on the Neuse River, the longest river in North Carolina. Working at the intersection of environmental protection, community engagement and activism, and on-the-river monitoring and sampling, riverkeepers play a unique role in helping to unite scientific research, law and government, and members of the community. Krop covered topics including engaging community members in the installation and maintenance of trash traps, water sampling, Sound Rivers’ popular summer swim guide , and more.

Speaker Layla El-Khoury explores the intersection of art and science

The second day of the conference l opened with an engaging presentation from Layla El-Khoury, a PhD student in the Biological and Agricultural Engineering department at NC State University. In addition to conducting research in improving methods for identifying, predicting, and quantifying streambank erosion, Layla is also a skilled dancer and choreographer, and weaves together aspects of science and dance by choreographing dance pieces inspired by her scientific research.

El-Khoury began by posing a question to her audience. What experiences, she asked, were more memorable to them: reading scientific papers or studies, or experiencing works of art like movies, books, and performances? As the audience agreed and Layla went on to demonstrate, art often sticks in our minds and impacts us in a way that a scientific text alone may not. Art that incorporates scientific research, Layla argued, is a way to leave a lasting impression while also raising awareness about environmental problems.

To further her point, she shared excerpts from two choreographed dance pieces, one focusing on streambank erosion and one focusing on plastics and microplastics in streams. These mesmerizing pieces communicated scientific concepts in a way that was aesthetically engaging and emotionally impactful.

View Layla’s beautifully choreographed dance pieces below:

• Plastics and microplastics in streams: Is There Away?
• Streambank erosion: Force of Flows

U87 – Baseflow and storm-based water quality: from observations to urban stream imagery analysis

Katherine Atkins / Earth & Environmental Sciences / Faculty Mentor: Ricardo Sanchez-Murillo

Persistent droughts, extreme precipitation events, and increasing water needs are shaping the co-evolution of Texas’s urban assemblages, water laws/regulations, stormwater management, and future water supply allocation. In large urban centers such as the Dallas-Fort Worth (DFW) area, the spatial and temporal variability of water inputs (i.e., precipitation, lawn irrigation, storm flows, and wastewater) to streams alters the ecohydrological conditions of urban watersheds. Here, we present a preliminary study combining water quality, image analysis, and machine learning using high-resolution stream response imagery as part of an undergraduate research experience project. Baseflow and storm-based samples were collected in an urban highly altered stream and analyzed for water stable isotopes (18O and 2H) and selected parameters (nitrate, iron, phosphorous, total organic carbon, tannin, and lignin, turbidity). Isotope compositions are used to understand water portioning processes during storm events (old vs new water paradox), while water quality parameters are linked to the stream response images. Our results aim to reveal previously unknown water-mixing processes in urban streams and train a machine-learning model to evaluate solute and contaminant transport from a stream imagery perspective.

U.S. EPA Finalizes PFAS Drinking Water Standards — Now What?

Steven Siros

In what should come as a surprise to no one, on April 10, 2024, U.S EPA finalized its National Primary Drinking Water Regulation for six per- and polyfluoroalkyl substances (“PFAS”).  These final standards are summarized below:

Public water systems (“PWS”) will have three years to complete initial monitoring for these six specific PFAS to be followed by ongoing compliance monitoring.  If found in the drinking water above these standards, the PWS will have five years (2029) to implement solutions to reduce the PFAS to below these regulatory levels and provide public notification of the exceedance.

But what do these new PFAS drinking water standards really mean for the regulated community?  We already know that as a result of data being collected in connection with U.S. EPA’s Fifth Unregulated Contaminant Monitoring Rule , PFOA and PFOS have been found in more than ten percent of the PWS that were required to sample and there is no reason to believe that this trend will be any different once all PWS are required to sample for these specific six PFAS.

Notwithstanding recent court approval of the multi-billion-dollar settlement with public water utilities, to the extent that any of these six PFAS are identified above the recently promulgated regulatory levels, impacted PWS are still likely to cast a wide net looking for other entities to contribute to the costs to address the PFAS-impacted drinking water.   And U.S. EPA’s ongoing efforts to implement its PFAS Strategic Roadmap will continue to generate data that can be relied on by PWS in searching for additional “responsible parties”. 

For example, in November 2023, U.S. EPA finalized a rule eliminating the de minimis exemption for reporting for 189 PFAS in Toxic Release Inventory (“TRI”) reports.   U.S. EPA estimated that by eliminating the de minimis reporting exemption, an additional 2,000 companies would be required to file TRI reports on PFAS releases into the environment.  Similarly, U.S. EPA’s recently promulgated PFAS Reporting Rule under the Toxic Substances Control Act requires companies to provide data on PFAS in consumer and industrial products dating back to 2011.  The rule requires that any entity that manufactured or imported PFAS, PFAS-containing articles, PFAS in mixtures, byproducts or as an impurity, provide specific information regarding PFAS uses, production volumes, disposal, exposures, hazards and environmental and health effects.  There is no de minimis reporting threshold under this rule. 

So there will soon be a lot of information flooding the public arena regarding historical and ongoing uses of PFAS that will likely be mined by PWS and other entities seeking to find potentially responsible parties to contribute to the costs to remediate PFAS-impacted drinking water.  In order to both mitigate risk and ensure compliance with applicable reporting requirements, companies would be well served to carefully audit their supply chain to identify potential PFAS uses.  Of course, that can pose a challenge where the PFAS might not be disclosed on safety data sheets or where there is uncertainty regarding what actually constitutes a PFAS.   

We will continue to monitor and report on new PFAS developments at the Corporate Environmental Lawyer Blog . 

EPA announces enforceable standards for several common 'forever chemicals' found in U.S. drinking water

F ederal officials on Wednesday released long-anticipated legally enforceable standards for several "forever chemicals," setting benchmarks well below Wisconsin's current regulations and delivered as part of a goal of moving toward no detectable contamination in drinking water across the country.

The Environmental Protection Agency announced the new standards along with $21 billion to address the issue nationwide.

The new enforceable standard for PFOA and PFOS is 4 parts per trillion, while the non-enforceable health-based goal is now 0 ppt, according to i nformation from the agency . PFOA and PFOS are two of the most well-known and well-researched compounds in the PFAS family, and were used in things such as Teflon pans and firefighting foam.

Get daily updates on the Packers during the season.

The Wisconsin standard, implemented last year , is 70 parts per trillion but the state will now have to follow the federal standard.

For PFNA, PFHxS, and GenX, the new standard is 10 parts per trillion.

And because PFAS are often found together in mixtures, the EPA also set a limit for any mixture of two or more of PFNA, PFHxS, PFBS and GenX.

The new rule comes nearly 25 years after the discovery of PFAS in Cape Fear, N.C., stemming from a local DuPont plant contamination that caused illnesses in the community and in animals. The discovery of the toxic chemicals — and the discovery that manufacturers knew of the risks associated with them — was immortalized in the movie "Dark Waters."

But since then, environmental advocates have been pushing the federal government to regulate the compounds to protect human health. President Joe Biden launched efforts to devise a comprehensive plan to address the chemicals after taking office in 2020. The federal agency released its initial "PFAS Roadmap" in 2021.

Wednesday's standards were released after consultation with the water sector and with state regulators to ensure effective implementation and considering 120,000 comments on the proposed rule, according to a press release.

“Drinking water contaminated with PFAS has plagued communities across this country for too long,” EPA Administrator Michael S. Regan said in the press release. “Our PFAS Strategic Roadmap marshals the full breadth of EPA’s authority and resources to protect people from these harmful forever chemicals. Today, I am proud to finalize this critical piece of our Roadmap, and in doing so, save thousands of lives and help ensure our children grow up healthier.”  

The EPA estimates that 6% to 10% of the 66,000 public drinking water systems in the U.S. will have to take action to reduce the level of PFAS in their water. All systems will have three years to complete the initial monitoring and inform the public. Systems will have five years to address levels of PFAS above the standards.

Katie Rosenberg, the mayor of Wausau where PFAS levels in all of its municipal wells were above the new rules , called the new standards "historic" and also challenging for communities to meet.

"Five years isn't a lot time to plan for major upgrades to drinking water infrastructure," she said in a text message.

"And on a personal note, it will take political bravery to make the necessary investments. But the health and safety of out neighbors and generations of future Americans depend on all of our leadership to get this work done. Politics be damned, water is essential to life."

Rosenberg lost her re-election bid last week after complaints about the cost of water due to the newly implemented filtration system , installed to remove PFAS.

By contrast, Wisconsin implemented standards for drinking water at 70 parts per trillion for PFOA and PFOS last year. Those limits matched the federal guidance put in place in 2016, but hadn't been updated to reflect the emerging science. The state does not have regulations for groundwater in place, which the federal government does not regulate.

According to the DNR, the current standard will remain in place until the agency completes rule-making to comply with the EPA rules, which could take up to three years.

A Milwaukee Journal Sentinel investigation in 2022 found that out of 40 public water systems that were tested, nearly half had detection of PFAS.

And according to testing implemented by the Department of Natural Resources since then, several more public water systems have had detections of PFAS above the limits now put in place by the federal government and will need to take action.

“Overall, Wisconsin’s public water systems are well positioned to comply with the EPA’s enforceable standards,” Steve Elmore, director of the DNR’s Bureau of Drinking Water and Groundwater, said in a statement. “The DNR set enforceable standards for two types of PFAS in public drinking water in 2022. Over the last year, public water systems throughout Wisconsin have sampled at least once for these and other PFAS.”   

In addition to the standards, the Biden Administration announced funding to help public water systems address PFAS. Of the $21 billion, $9 billion will be used specifically for tackling PFAS and other emergency contaminants.

In particular, the EPA will help small, rural and disadvantaged communities access the federal resources.

Wisconsin struggling to address PFAS

As the federal government moves to protect Americans from PFAS, Wisconsin is struggling to decide how to address the chemicals.

Democratic Gov. Tony Evers v etoed a Republican-authored bill Tuesday that would have created a framework to spend the $125 million "PFAS trust fund," and asked the state's powerful budget committee instead to hold a special session in order to release the funds to the DNR.

Republicans criticized Evers' veto and are unlikely to release the funding.

Meanwhile, the state also faces an uphill battle on the regulation of PFAS in groundwater, upon which a large majority of Wisconsinites rely on for their drinking water. The 30-month process to set standards has now failed twice, leaving residents with contamination in their private wells with questions and a lack of access to resources.

What are PFAS?

PFAS, or per- and polyfluoroalkyl substances , are a family of man-made chemicals used for their water- and stain-resistant qualities in products like clothing and carpet, nonstick cookware, packaging and firefighting foam.

The family includes 5,000 compounds, which are persistent, remaining both in the environment and human body over time.  The chemicals have been linked to types of kidney and testicular cancers, lower birth weights, harm to immune and reproductive systems, altered hormone regulation and altered thyroid hormones.
