Dead Fish in Unicorn Lake, Denton, TX.

Officials determined the most likely cause of the large number of fish deaths was a temporary drop in dissolved oxygen, either due to recent weather conditions or algae activity within the pond.  Skeptics said that a more likely cause was overflow from an upstream pond known to be polluted with raw sewage.  Full Story: Denton Record Chronicle.

Uncle Putin, Give Us Water

Children in occupied Ukraine have adopted the plea “Uncle Putin, give us water” in imitation of past generations’ pleas for mercy addressed to oppressive Russian rulers.
Residents of Donetsk and other parts of the Donbas region occupied by Russia since 2014 are suffering from a water shortage that threatens to escalate into a humanitarian catastrophe. In many households in this war-torn region, water currently flows only every three days for a few hours. When it finally runs from the tap, the water is often blackish, foul-smelling, and unfit for consumption. The water pressure in the pipes is so low that the upper floors of apartment buildings are not supplied. Full story in Le Monde.

World Resources Institute Paints Bleak Picture Regarding Water Security

A total of 25 countries – home to a quarter of the global population – face extremely high water stress each year, regularly using up almost their entire available renewable supply.
That is according to a new report by the World Resources Institute (WRI), which defines a country facing ‘extreme water stress’ as one that uses 80% of its available renewable water supply annually.

The six most water-stressed countries are Bahrain, Cyprus, Kuwait, Lebanon, Oman and Qatar, leaving them vulnerable to shortages.

The research also found that half of the world’s population — around four billion people — live in countries under ‘highly water-stressed conditions’ for at least one month of the year, using 40% of their supply. ISEP.

Heavy Flooding Worldwide

Sudden floods triggered by heavy rains have killed more than 400 people across parts of Pakistan, India-administered Kashmir and Nepal with scores of people still missing.

In northwestern Pakistan, at least 321 people were killed in the space of 48 hours with more than ten villages in the Buner region of the Khyber Pakhtunkhwa province devastated by flash flooding.
It comes after India’s Meteorological Department said on Wednesday that the rainfall was due to a “cloudburst,” which is a sudden and heavy downpour of more than 100 millimeters (4 inches) of rain in just one hour.

Analysts warned the human-made climate crisis has exacerbated the intensity and frequency of seasonal floods in the Himalayas this year.  MSN

Non-Revenue Water Resulting from Chlorine Sensors

Non-revenue water (NRW) losses are a significant concern for drinking water utilities worldwide because they represent water that is produced but does not generate revenue, impacting both financial sustainability and resource management. Water is lost through leaks, pipe bursts, or overflows in the distribution system. Aging infrastructure, poor maintenance, and high system pressures often contribute to these losses.

One often overlooked source is water losses generated from chlorine sensor waste streams. Most chlorine sensors require 70,000 gallons (265,000 liters) or more per year per sensor of treated water to be disposed of. This is true for online DPD instruments but also amperometric sensors. With an estimated 88,268 analyzers in operation across 29,423 chlorine-using community water systems, the total wasted water is 6,178,771,200 gallons (23,390,000,000 liters) per year. — Water Online

Five Dead in NYC from Legionnaires’ Disease

Four people in New York City’s Harlem neighborhood have died from an outbreak of Legionnaires’ disease, an aggressive and potentially deadly form of pneumonia. The city has seen 99 confirmed cases with 17 people in hospital with the infection, according to the New York City Department of Health.  Officials have traced the outbreak back to 12 cooling towers on 10 buildings where bacteria were growing, including at a hospital and a health clinic.  Eleven of the 12 cooling towers have undergone remediation efforts, and the final one is expected to be fixed with the week, according to New York Mayor Eric Adams.

Since the outbreak began on July 25, the New York City Health Department has reported 108 cases of Legionnaires’ disease in Central Harlem — a historically Black neighborhood in Upper Manhattan. The latest death was reported on Aug. 18 after health officials concluded that a person with the disease who died before mid-August was associated with the Central Harlem cluster.

Legionnaires’ disease is relatively rare, with less than 18,000 people hospitalized in the US every year, according to medical research center Cleveland Clinic.

Transmission does not happen from person-to-person contact, but rather by mist in the air. The Legionella bacteria grows in stagnant, warm water, like the water that collects at the bottom of building cooling towers. The risk of serious complications from the disease, including lung failure and death, is highest for people aged 50 over as well as for smokers.  MSNBC 

Effort to End the World Plastics Pollution Crisis Fails

Negotiators in Geneva have rejected the draft treaties for an agreement to end the plastics pollution crisis. The main sticking point has been whether the treaty should impose plastic production limits or focus instead on waste management, recycling and reuse, with oil- and gas-producing countries and the plastics industry opposing production limits. Countries in the latter camp include Saudi Arabia, Russia and Iran, reportedly with the support of the US.  The Guardian 

Is Natural Mineral Water Still Natural if it has been filtered?

This is a debate that has been going on in France since the 18th century. The debate has heated up.  See the full story in The Conversation. 

Water levels at Lake Powell, the giant reservoir on the Utah-Arizona border, have dropped to their lowest point in three years, prompting boat ramp closures and raising fears about downstream water supplies and hydroelectric power generation that could affect millions of people across the West.

Of greater concern in the long term is how dropping water levels will impact both power generation and water supply: There’s a chance that Lake Powell’s water level could fall to an elevation that would force the stoppage of power generation at the Glen Canyon Dam, which would affect electricity supply to millions of people in many states.  USA Today.

The U.S. National Park Service announced that one of the primary boat launches within the Glen Canyon National Recreation Area in Utah – the Wahweap Main Launch Ramp – will be closed starting Aug 18. And the Park Service is relocating the Rainbow Bridge floating dock into deeper water.

Action at the EPA

We decided to skip reporting EPA actions for August. They were numerous and very much the same. Most EPA activity for August consisted of rolling back regulatory policies of previous administrations in an effort to “make America great” by freeing businesses from onerous environmental protection standards.

Outrage in Iowa–Residents demand action to clean up dangerously polluted water

by Carey Gillam

Pure Water Gazette Note: The article below reflects the public demand for regulation of water polluters. It shows how out of touch the current Washington administration is. The new administrator of the EPA, Lee Zeldin, has made clear that under the new administration the regulation of water contamination will be significantly narrowed, as such regulatory principles as the strict enforcement of “water of the United States” laws  “placed unfair burdens on the American people and drove up the cost of doing business.”  Zeldin has made clear that the EPA’s focus will now turn to freeing business from the onerous concerns of water protection. Is that what people want? The Iowans described below seem more concerned about shutting down the cancer epidemic than helping agribusiness avoid those inconvenient water protection  rules. 

DES MOINES, Iowa — Several hundred Iowa residents gathered in the state capital this week, calling on public officials – and each other – to take swift action against dangerously polluted water supplies that are closely linked to the state’s powerful agricultural industry.

Some attendees drove for hours from rural farmsteads for the Aug. 4 event, squeezing into a packed auditorium on the campus of Drake University to listen to a team of scientists detail new research showing how multiple harmful pollutants flowing through Iowa watersheds are jeopardizing public and environmental health.

The crowd cheered and applauded loudly as speakers outlined a need for new regulations on farm pollution, while discussion of a decision by public officials to slash funding for water quality monitoring devices drew a chorus of boos. Organizers said roughly 800 attended in person and another 400 participated online.

The forum focused on data in the research report, which was commissioned by Polk County officials in Des Moines and released by county commissioners last month. It adds to years of mounting evidence that pesticides, fertilizers, manure and other contaminants from Iowa farms and livestock operations are contaminating waterways used for drinking water, fishing and swimming, and likely contributing to the rising cancer rates that are impacting families across the state.

“Where do we want the state to be in 25 or 50 years?” Larry Weber, a University of Iowa scientist who helped author the water report, asked the audience. “When are we going to start to make the choices that put us in a position that move us in the right direction?”

Seeking a ‘course correction’

Iowa has the second-highest rate of cancer in the nation, and has become one of only two US states where cancer overall is increasing. Leukemia, as well as cancers of the pancreas, breast, stomach, kidney, thyroid and uterus, are among the different cancer types on the rise across Iowa, according to the National Cancer Institute.

Many of the chemicals and other pollutants contaminating water sources are scientifically linked to these cancers as well as other health problems.

Nitrates, generated by fertilizer and manure, are a particular concern, routinely found in Iowa waters at levels above the 10 milligrams per liter federal regulators set as a safe standard. Babies are at risk for severe health problems when consuming nitrates in drinking water, and exposure to elevated levels of nitrates in drinking water has been linked by researchers to cancers of the blood, brain, breast, bladder and ovaries.

Nitrate levels this summer in Iowa have been so far above federal standards that the utility serving 600,000 people in and around Des Moines restricted water use because the utility could not safely clear the high levels.

Though the restrictions recently eased, on Aug. 5, the day after the forum, laboratory testing by the Central Iowa Water Works in Des Moines still showed unsafe levels of nitrates in water samples from the Raccoon River, one of the two main rivers that supplies the area’s drinking water.

A spokeswoman said the utility was currently drawing from other water sources due to the nitrate levels in the river.

State officials generally point the finger at smoking, alcohol use and other factors as driving the cancer rates, and have been reluctant to look too hard at agriculture, according to Adam Shriver, director of wellness and nutrition policy at the Harkin Institute at Drake who helped lead the drinking water forum this week.

“That part of the conversation [agriculture] oftentimes gets pushed down and pushed away,” he said. “Iowa has a long history of basically putting the thumb on the scale when it comes to looking at issues related to agriculture and public health.”

But public support for new regulations on agriculture appears to be growing, Shriver said.

“People want a course correction. They are not satisfied with what is being done now,” he said. “They’re tired of being told ‘oh yeah everything is fine, don’t worry about it.’”

‘Something in the water‘

Angela Connolly, a Polk County supervisor who has served in office since 1998 and who attended the Monday evening meeting, is among those whose patience has run out when it comes to Iowa’s water pollution problems.

“This was the largest crowd I’ve ever seen on a single subject,” she said. “We have to show the political will. We have to go to the state house and demand change for water quality.”

Connolly said her 47-year-old daughter-in-law has suffered from breast and colon cancer, and she knows of several other people in their 40s also suffering from cancer.

“I truly believe that there is something in the water and I want something done about it,” she said.

With nearly 87,000 farms, Iowa is a key producer of many agricultural products, ranking first in the production of corn, pork and eggs, and within the top five states for growing soybeans and raising cattle. Of Iowa’s 35.7 million acres of total land, roughly 31 million is devoted to farming. Agriculture contributes close to $160 billion to the state’s economy – roughly one-third of the state’s total economic output, according to the Iowa Farm Bureau.

Many farmers are among the voices calling for changes to help mitigate the pollution fouling the waterways. Those relying on private well water say they feel at particular risk from pollutants that are so prevalent in rural areas.

Seth Watkins, who traveled 120 miles from his farm west of Des Moines to attend the drinking water forum, said he has altered his farming practices to reduce contributing contaminants to the watershed, but still worries about the water – not just for his family, but also for his livestock.

He questions whether the chemicals contaminating the area contributed to the fact that both his children were born with health challenges.

“It would be great if we could do this voluntarily, but I don’t know any society in the history of mankind that has actually protected our natural capital without some level of enforceable regulation,” Watkins said.

‘Going backwards‘

A particular point of concern when it comes to water contamination is the abundance of large concentrated animal feeding operations (CAFOs) across the state that regularly generate large quantities of manure, and related agricultural businesses such as slaughterhouses.

Despite pleas from environmental groups, state officials have shown continued support for the animal operations.

In one contamination case angering Iowans, Agri Star Meat and Poultry, which operates a beef and poultry slaughterhouse in Postville, Iowa, was found to have exceeded wastewater limits roughly 60 times, leading to “acutely toxic concentrations” of ammonia in area waterways. The operation also failed to comply with monitoring and reporting requirements, according to a July 30 announcement from the Iowa Attorney General’s office.

The state has ordered the company to pay a $50,000 penalty and given it until the end of 2026 to come into compliance.The action by the state came after a local nonprofit sued Agri Star for allegedly violating water quality laws.

In another agricultural contamination case, NEW Co-op is paying a $50,000 fine for an ammonia nitrogen release last year that caused a “significant” fish kill along 48 miles of the Nishnabotna River that flows as a tributary of the Missouri River in southwestern Iowa.

As part of the settlement with the state, the company agreed not to violate Iowa’s water quality laws for three years.

The fertilizer spill and fish kill sparked farmer Denise O’Brien, who lives with her husband on the farm he grew up on in Atlantic, Iowa, to join with others in her area to start the Nishnabotna Water Defenders. The nonprofit focuses on monitoring and protecting the water quality in their region and is training people to test water and push for polluter accountability.

O’Brien said her mother and sister died of cancer and several neighbors suffer from ovarian, breast and pancreatic cancers as well as Parkinson’s disease. She and her husband drove with neighbors an hour and a half to attend the forum.

“Our public officials don’t have a political will,” she said in an interview following the forum. “There’s a lot of groundwork to do, not only testing water, but encouraging people to be involved politically, because people are just giving up … we’re going backwards now.”

In concluding the water meeting, organizers asked attendees to sign up for training to help with both water quality monitoring and with public advocacy efforts, and an environmental group offered free water testing kits for people to collect nitrate readings in their communities.

The audience responded with a standing ovation. The song “Bridge over troubled waters” played as they trailed out of the auditorium.

Gazette Fair Use Statement

By Christian Bonawandt

For a planet that is 71% water, Earth is in a shockingly short supply of drinking water sources. Freshwater comprises only about 3% of all water, and less than half of that is accessible to humans. New research published in the journal Science Advances reveals that this meager quantity has been rapidly dwindling for more than 20 years due to a combination of factors related to both climate and direct human activity. Using NASA Gravity Recovery and Climate Experiment (GRACE) satellite data, the research shows that areas experiencing drying have been expanding at a dangerous rate since 2002, depleting available drinking water for 75% of the world’s population and contributing to rising sea levels.

According to the report, the single largest threat to terrestrial water storage (TWS) in non-glacial regions is groundwater depletion. Over-pumping of groundwater accounts for 68% of TWS losses, which exacerbates the impacts of rising temperatures, aridification, and extreme drought events. This is especially noticeable in California’s Central Valley, the southern Ogallala Aquifer, the Northwestern Sahara Aquifer System, the Arabian Aquifer System, and the Tarim, Indus, Ganges-Brahmaputra, and North China Aquifer Systems. In many areas, groundwater is being depleted at unsustainable or even increasing rates. “It’s like this sort of creeping disaster that has taken over the continents in ways that no one was really anticipating,” Jay Famiglietti, one of the study’s co-authors, told ProPublica.

Even worse, much of the extracted groundwater is discharged back into the ocean. Not only does this make it harder to use for drinking water, but it is also contributing to rising sea levels. Since 2015, freshwater discharges have become the primary source (44%) of rising sea levels, surpassing the melting ice sheets in Greenland (37%) and the Antarctic (19%).

But irresponsible handling of groundwater is far from the only factor impacting existing and potential drinking water supplies. High-latitude water losses, particularly in Canada and Russia, are happening due to rising temperatures and declining precipitation. The study shows that these areas are warming at approximately four times the global average rate, leading to drying of subarctic lakes and persistent drought in regions like the Canadian prairies. Extreme drought events in Central America and Europe over the past several years have been another significant driver. These include catastrophic droughts in Europe — some of the worst in 2000 years — that are influenced by climate change, as well as widespread drying across North Africa. The same factors causing extreme drought are also causing declines in surface water, such as rivers and lakes, which account for 18% of TWS losses. The result is what the authors call “mega-drying regions”, which have been spreading across Earth’s mid-latitudes. These are areas where drying hot spots have overlapped, accelerating the problem for all those who live in and around them. The study has identified one or more mega-drying regions on nearly every continent.

Looking ahead, the authors foresee concerning conditions. The report predicts the rates of continental drying will increase in the coming decades, leading to an accelerated decline in freshwater availability. Moreover, there is little indication that these trends will reverse, and there are currently no natural or man-made mechanisms that can replenish water resources before they run out.

That doesn’t mean humanity is doomed, however. Instead, the authors suggest that local, national, and global communities prioritize groundwater sustainability. This includes both slowing rates of groundwater extraction and facilitating large-scale groundwater recharge programs. In addition, the authors call for major coordinated transdisciplinary efforts. The goal is raise awareness and motivate action around continental drying and decreasing freshwater availability, bringing them to the same level of global attention and policy focus as the carbon cycle.

The Reverse Osmosis Flow Restrictor

The flow restrictor is located in the yellow drain line of your Black and White reverse osmosis unit. The number indicates its output in mg/L.

The flow restrictor’s function is to regulate the flow of brine, or reject water, leaving the RO membrane housing. It is an essential part of the reverse osmosis process. If the restrictor allows too much water to exit the housing, the RO unit will not produce enough water; too little flow through the restrictor will damage the membrane and lower the quality of the water produced.

The number printed on the restrictor indicates its approximate output in mg/L. Actual output can vary and is influenced by such factors as inlet water pressure, water temperature, and general water quality.

To test the restrictor, turn off the storage tank valve and open and leave open the ledge faucet. When a small stream or fast drip of water is coming from the faucet, it means the unit is making water. Remove the drain line from the undersink drain saddle. There should be a small stream flowing from the drain tube. Catch the stream in a measuring cup that measures milliliters and time for one minute.  The output should be more or less the same as the number printed on the restrictor. If the actual output is in the ballpark of the number printed on the restrictor, all is well. If it’s way off, the restrictor should be replaced.

Be sure to replace the restrictor with the size that matches your membrane. See our Reverse Osmosis Parts page for replacement restrictors.  Make sure you get the restrictor that matches you membrane size, as explained on the page.

40% of Glaciers Are Doomed 

Almost 40% of glaciers in existence today are already doomed to melt due to climate-heating emissions from fossil fuels, a study has found. The loss will soar to 75% if global heating reaches the 2.7C rise for which the world is on track. The massive loss of glaciers would push up sea levels, endangering millions of people and driving mass migration.  The Guardian.

De Not Eat Warnings for Fish in Michigan

Amid evidence that PFAS is far more dangerous than previously thought, state officials have revised statewide guidelines for eating contaminated fish.

Michigan health officials have dramatically reduced the amount of PFAS-tainted fish they consider safe to eat, tripling the number of water bodies where anglers are warned against eating their catch.

Ninety-eight water bodies are now subject to “do not eat” advisories because fish are contaminated with the so-called “forever chemicals,” up from 33 last year. Hundreds more advisories suggest that Michiganders limit meals of certain fish species to anywhere from 16 servings a month to six a year.

Officials with the Michigan Department of Health and Human Services announced the change Monday while publishing the annual Eat Safe Fish Guide, a document that identifies waterways where fish are contaminated with unsafe levels of toxic chemicals. Bridge Michigan

Salmonella Traced to Cucumbers Grown in Contaminated Irrigation Water

A salmonella outbreak tore through the country last spring and summer, infecting more than 550 people and sending 155 to the hospital.

The likely culprit wasn’t raw eggs or undercooked chicken but an innocuous salad staple: cucumbers.

One year later, cucumbers are once again making people sick — and federal officials say that one of the same Florida farms is once again involved. Forty-five people in 18 states recently contracted salmonella in an outbreak linked to cucumbers from Bedner Growers in Palm Beach County, setting off a widespread recall that has affected everything from California rolls sold at Target to banh mi sandwiches served at a North Carolina high school.

The Food and Drug Administration has yet to explain how the cucumbers linked to the current outbreak became contaminated; the investigation is ongoing. But last year, the agency found that Bedner Growers had used untreated canal water for irrigation — and that the water was contaminated with one of the salmonella strains that had made people sick.

Cucumbers and other fresh produce may be a surprising source of salmonella, which can cause diarrhea, stomach cramps and fever, as well as more serious health problems that can turn fatal. Heat from cooking can kill the bacteria, but fruits and vegetables that are eaten raw, like cucumbers, can be unsafe once they are contaminated. That means it’s particularly important to protect fresh produce from pathogens lurking in water used for irrigation or washing.   NBC News.

Expectant Mothers Advised to Drink Filtered Water

Pregnant women have been advised to use water filters by experts who spoke to Newsweek after a study found levels of arsenic in water systems considered safe are impacting birth outcomes.

A national study led by researchers at Columbia University evaluated risks from 13,998 pregnancies across 35 cohort sites participating in the National Institutes of Health’s Environmental influences on Child Health Outcomes (ECHO) program, and published its findings on the medical journal site JAMA Network last week.

The researchers discovered that prenatal exposure to arsenic was associated with a higher likelihood of babies being born preterm with lower birth weights, factors that they said are important “predictors of infant mortality and morbidity across the life span.”

This was the case even at the level of exposure the Environmental Protection Agency (EPA) currently deems safe, 10 micrograms per liter, a regulation that was established in 2001 and has not been changed since.  Newsweek. Full article.

How to Disinfect a Well

Information from National Testing Laboratories.

To disinfect a private well . . .

1. Remove well cover. Pour the required amount of bleach into the well. See the list below.

2. Run ALL faucets in the house, one at a time, until you smell the chlorine at the faucet. This ensures that the whole system will be disinfected

3. Connect a garden hose to an outside tap or an indoor tap with the correct thread fitting. Put the other end of the hose into the well, turn on the faucet, and from time to time move the hose so that the chlorinated water bathes the sidewalls of the well casing. Do this for at least six hours. Turn off tap and remove the hose from the well.

4. Replace the well cover

5. DON’T USE THE WATER for at least twelve hours. Forty-eight hours in optimal.

6. Run the water to waste but NOT INTO THE SEPTIC SYSTEM for several hours, or until the chlorine taste is dilute enough to be unobjectionable. The best way to run the water to waste is to use the garden hose mentioned above (item 3). Direct the hose into an area where the chlorinated water will not cause environmental damage or affect the water supply of others. For a typical well, this may take 3-4 hours. NOTE: To avoid pump overheating and possible damage, turn off the water when flow is at a trickle and wait at least 15 minutes before turning on the pump again

7. After a week of use, retest for bacteria.

8. In some cases, one chlorination treatment WILL NOT be sufficient. Repeat disinfection procedures as needed.
