A new study revealed that the breakdown of petroleum underground can release arenic into groundwater
In a long-term field study, U.S. Geological Survey (USGS) and Virginia Tech scientists have found that changes in geochemistry from the natural breakdown of petroleum hydrocarbons underground can promote the chemical release (mobilization) of naturally occurring arsenic into groundwater. This geochemical change can result in potentially significant arsenic groundwater contamination.
A recently filed C8 lawsuit purports a 61-year-old Ohio woman developed high cholesterol as a result of consuming water contaminated by the C8 chemical released by DuPont’s Washington Works Plant in West Virginia. The Ohio woman asserts that from 1953 to present, she attended school and lived in the affected Lubeck Water Public Service District, City of Belpre Water District, Little Hocking Water Assn. and Tuppers Plains-Chester Water District.
This treatment process is ideal for small communities out of compliance with federal and state drinking water regulations
AdEdge Water Technologies was awarded and is implementing a biottta (biologically tailored two-stage treatment approach) nitrate removal project for the city of Delano, Calif. The city of Delano, a community of 38,000 residents, is located in the San Joaquin Valley, approximately 30 miles north of Bakersfield. The current levels of nitrate are not compliant with the California drinking water standard of 45 mg/L nitrate as NO3.
The site is contaminated with TCE and PCE, which have serious health effects
The Department of Justice and the U.S. Environmental Protection Agency (EPA) announced a proposed settlement with several companies to address the Pohatcong Valley Groundwater Contamination Superfund site in Warren County, N.J. The companies are Pechiney Plastic Packaging Inc., Albéa Americas Inc., Bristol-Myers Squibb Co., Citigroup Inc., and Rexam Beverage Can Co. The Pohatcong site is contaminated with trichloroethylene (TCE) and perchloroethylene (PCE), which can have serious health effects.
A study by Friends of the Earth Scotland reveals that pollution levels around the world are breaking limits
Blueair, a Sweden-based provider of indoor air cleaning technology appliances, said a recent Friends of the Earth claim that air pollution in Scotland is creating a public health crisis highlights the lack of public awareness about toxic pollutants in the air people breathe both outside and inside their homes and offices.
Supai, Ariz., is the capital of the Havasupai Indian Reservation in the western Grand Canyon. The reservation is the site of some of the country’s most beautiful waterfalls and is a popular destination for hikers and backpackers. In fact, hiking is one of the few ways to reach Supai, which is the only place in the U.S. where mail is still delivered by mules. The nearest surfaced road is 9 miles away.
The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring an average of 54 cu meters of water per metric ton of finished product. As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water and state-of-the art water treatment.
A variety of scientifically defensible documents can be downloaded from EPA’s website
The U.S. Environmental Protection Agency (EPA) is providing information to assist risk assessors and scientists in the development of rigorous and scientifically defensible risk assessments for waterborne pathogens.
The system reduces contaminants such as pharmaceuticals from drinking water
Later this month, Pentair will release its newest product, the H-300-NXT, an addition to its Everpure residential line of luxury water filtration products. The system reduces emerging contaminants like pharmaceuticals, over-the-counter medications and chemical compounds like bisphenol A that may be found in drinking water.
The manufacturer states that the larger filter design provides greater dirt-holding capacity, “ideal for parts of the country where high silt content in water is a concern.”
Program to serve as a model for similar programs across the country
