A study in the State of New York conducted over the past twelve years by the US Geological Survey found elevated levels of methane in 9% of the state’s groundwater. The findings are consistent with measurements in the rest of the Northeast.
Methane is highly flammable and a potent greenhouse gas. Of particular concern is that 2% of [...]Continue Reading →
Centers for Disease Control investigators found the deadly amoeba Naegleria fowleri in the tap water of two Louisiana residents who died from primary amoebic meningoencephalitis in 2011. These are the first cases in the US that have been linked to N. fowleri in household plumbing served by municipal water. According to the Food and Drug [...]Continue Reading →
The Western Municipal Water District in Riverside County approved the expansion of the West Riverside Wastewater Treatment Plant. The expansion will increase the capacity of the facility by over 5 million gallons per day, which will be used to recharge groundwater supplies.
Michele McKinney Underwood, a Western spokeswoman, called the wastewater recycling project, “a way [...]Continue Reading →
Cadiz has been trying to sell groundwater from the Mojave desert to Southern California cities for 15 years. The environmental impact report for the project was accepted last week by the Santa Margarita Water District in Orange County. Santa Margarita also agreed to buy one-tenth of the project’s proposed annual yield. If it goes ahead [...]Continue Reading →
Risk analysts at SUNY Stony Brook say that treatment of wastewater represents the greatest hazard that fracking operations pose to drinking water safety. The researchers say that industrial water treatment plants are generally unable to handle wastewater from hydraulic fracturing. They determined that this makes wastewater disposal orders of magnitude more hazardous than the potential for wells to leak [...]Continue Reading →
The Pepacton Reservoir, which normally provides New York City with a quarter of its drinking water, was re-connected to the city’s distribution system last week. It had been closed to drain and repair leaking fuel tanks that contained 3200 gallons of diesel fuel and gasoline. The Department of Environmental Protection believes that the tanks were left behind [...]Continue Reading →
The EPA announced yesterday that it has completed its sampling of water from private homes in Dimock, PA. The sampling program was undertaken based on concerns regarding contamination from nearby hyrdaulic fracturing, or “fracking”, operations. However, the EPA did not detect elevated levels of any of the contaminants studied.

24 million gallons of spilled jet fuel have contaminated an aquifer in Albequerque, and are making their way towards the wells that serve as the city’s primary source of drinking water. The spill occured over a period of 40 years at Kirtland Air Force Base, two miles from the nearest drinking water well. The plume [...]Continue Reading →
A plan to sell groundwater from the Mojave desert to the Metropolitan Water District of Southern California hit a roadblock when testing showed that the water contains 14 – 16 parts per billion of chromium-6. The public health goal in California is 0.02 parts per billion. The plan may still go ahead, but Metropolitan is [...]Continue Reading →
A study by the US Geological Survey found high levels of nitrate in 25 percent of the Upper Santa Ana Watershed, high levels of perchlorate in 11 percent of the of the aquifer system, and moderate levels in a further 53 percent. This aquifer system is used to provide drinking water to the Inland Empire. The study [...]Continue Reading →
The City of Redlands has begun work on an $8.5 million improvement project to bring its surface water treatment plant into compliance with EPA regulations for disinfection by-products. Assistant utilities director Chris Diggs explained that, “when organics – (or the) carbon – come in contact with chlorine these certain acids are formed. And these acids are [...]Continue Reading →
Officials at the Ohio Department of Public Health are offering free arsenic testing to owners of private wells in the State. The data will help them work with the US Geological Survey to identify areas where groundwater contains dangerously high levels of arsenic. Arsenic is a naturally occuring contaminant in many parts of the US, and has been linked [...]Continue Reading →
Warmer summers could cause more frequent blooms of toxic blue-green algae (also known as cyanobacteria), and cause them to produce more toxins. Cyanobacteria are naturally occuring in reservoirs, and blooms in drinking water supplies have been linked to gastrointestinal disorders, and other illnesses.

A study by the US Geological Survey has identified the presence of contaminants in potentially harmful concentrations in some New England bedrock groundwater supplies. Among the natural and man-made chemicals most commonly detected were arsenic, uranium, radon, nitrates, MtBE, and chloroform. Many of these were frequently detected above their EPA’s Maximum Contaminant Level.
“This study confirmed [...]Continue Reading →
A press release from the National Ground Water Association yesterday details steps owners of private wells should take to ensure the safety of their drinking water after a flood. In addition to contamination of the well water with bacteria and chemicals, they also point out the danger of electrical shock if the well’s electrical system has [...]Continue Reading →
The New Jersey Department of Environmental Protection has tested water quality in private wells since 2002. The results show that a significant number of those private wells contain levels of arsenic, mercury, nitrates, and volatile organic chemicals deemed unsafe by the US Environmental Protection Agency for public drinking water systems.
Overall, one in eight [...]Continue Reading →
The Rivanna Water & Sewer Authority’s will hold a meeting to discuss its decision to use chloramines as a secondary disinfectant. The proposed change will effect approximately 60,000 customers in Charlottesville and the surrounding Albemarle County. The use of chloramines is approved by the EPA for drinking water disinfection, but some negative health impacts have been reported, including [...]Continue Reading →
A recent study suggests that psychiatic drugs could cause autism. Researchers at Idaho State University found that Prozac, Effexor, and Tegratol activated the same genes in fathead minnows that are associated with idiopathic autism in humans. While these drugs have been detected in drinking water, they have not been found at the levels used in [...]Continue Reading →
The EPA has suggested demolishing three buildings at a Superfund site in downtown Columbus, OH to clean up soil contaminated by local dry cleaners. The soil contains tetrachloroethylene, a carcinogenic chemical commonly used in dry cleaning, and has been contaminating local groundwater since the 1980′s. The EPA believes that demolishing the buildings will facilitate the cleanup process.

Researchers at the Marshfield Clinic Research Foundation and the University of California, Davis discovered that viruses were present in a quarter of Wisconsin drinking water systems that do not disinfect their water. The authors of the study believe that this has a significant impact on the health of those communities: between 6% and 22% of all cases [...]Continue Reading →
