EPA publishes its fourth Draft Contaminant Candidate List
To ensure continued protection of public health, the U.S. Environmental Protection Agency (EPA) has published for public review and comment a draft list of contaminants that are not currently regulated in drinking water, but may require regulations in the future under the Safe Drinking Water Act (SDWA). The agency will evaluate and consider the public comments on developing the final Draft Contaminant Candidate List (CCL 4) and suggestions for improvements to the process for future CCLs.
In the late 1990s, a coking facility in Detroit closed, and the site was subjected to strict cleanup requirements as part of new government regulations. As part of the overall site cleanup, the facility was required to capture groundwater contaminated with creosote oil, aromatic hydrocarbons, ammonia and iron, and prevent it from migrating off site and contaminating surrounding areas. The final destination for the groundwater was a municipal wastewater treatment plant.

A new study found that septic systems leak man-made pollutants into groundwater
Pharmaceuticals, hormones and personal care products associated with everyday household activities are finding their way into groundwater through septic systems in New York and New England, according to the U.S. Geological Survey (USGS).
EPA's cancellation of certain methomyl uses will reduce risks to drinking water
The U.S. Environmental Protection Agency (EPA) and the manufacturers of the insecticide methomyl have agreed to cancel some uses and limit use on certain crops to reduce risks to drinking water. From 1995 to 2013, exposure from food to carbamates, which includes methomyl, has fallen by approximately 70%. The action is a continuation of EPA’s effort to reduce carbamate use, thereby protecting people’s health, especially the health of children who may be more sensitive to pesticides.
Project for city of Delano will implement biottta technology
AdEdge Water Technologies announced it was awarded and is implementing a biottta (biologically tailored two-stage treatment approach) nitrate removal project for the city of Delano, Calif.
AdVantEdge POE and POU systems for arsenic removal feature Bayoxide E33 media technology. The systems require no chemicals, no regeneration and minimal maintenance. Spent media is nontoxic and can be discarded as nonhazardous waste.
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.
