Study Finds High Concentrations of Organic Solvents in California Groundwater

Results show effects of industry and agriculture on groundwater quality

Organic solvents were detected at high concentrations in 18% of the aquifer system used for public supply in the San Fernando and San Gabriel basins in California in a U.S. Geological Survey (USGS) study. However, this groundwater treated before delivery to customers to ensure compliance with water quality standards.

By comparison, in most of the California areas previously studied, organic solvents were often detected in groundwater, but not at high concentrations. Statewide, high concentrations of organic solvents were found in less than 2% of the groundwater.

Pennsylvania DEP will host four online sessions in March and April

The Pennsylvania Department of Environmental Protection (DEP) will host online information sessions on implementing Act 13, which Gov. Tom Corbett signed into law in February to further protect the environment and place more stringent regulations on the natural gas drilling industry.

“Act 13 reaffirms our strong commitment to safe, responsible, environmentally sensitive and transparent natural gas development here in Pennsylvania,” said DEP Secretary Mike Krancer. “Our intent with these sessions is to explain the law and answer whatever questions people may have.”

The Deal on Dewatering

Wellpoint dewatering is the process of removing groundwater temporarily from soils in a localized area to complete the construction of a foundation, pipeline or other below-ground structure or to perform soil remediation.

Typical wellpoint dewatering applications include:

EPA launches website as central information resource on anniversary

This year is the 40th anniversary of the Clean Water Act, the nation’s law for protecting our most irreplaceable resource. Throughout the year, the U.S. Environmental Protection Agency (EPA) and others will highlight the tremendous progress in reducing pollution since 1972, the many milestones along the way, the ways that the job is far from over and the tough challenges faced today and in the future. EPA has set up a webpage, www.epa.gov/cleanwater40, as the central location for information, activities, news and networking.

Model Predicts Groundwater Atrazine Levels Unlikely to Exceed EPA Standards

USGS study used 20 years of data to create new statistical models

A new model predicts that atrazine and its breakdown product deethylatrazine have less than a 10% chance of exceeding the U.S. Environmental Protection Agency’s (EPA) standard for public drinking water supplies in shallow groundwater in about 95% of the nation’s agricultural areas. Atrazine is a commonly used herbicide for weed control in corn and sorghum production.

These findings are based on new statistical models developed from almost 20 years of nationwide water quality monitoring data collected by the USGS National Water Quality Assessment Program (NAWQA).

Water Replenishment District of Southern California will host event at its headquarters

The Water Replenishment District of Southern California (WRD) this week encouraged the observance of National Groundwater Awareness Week to increase understanding of the vital importance of groundwater to the urban areas of southeast Los Angeles County, where 40% of the water used is groundwater. Rural areas of America are even more dependent on groundwater, which accounts for approximately 96% of the water supply.

R2 and M2-Series RO systems are engineered and manufactured for commercial and light industrial applications and for feed waters up to 10,000 TDS. These high-efficiency systems use low-energy membrane elements that deliver high quality water at low operating pressures. This in turn makes AXEON R2 and M2-Series the first low-energy brackish water systems in the marketplace.

The VZN Series uses three technologies to deliver better-tasting, scale-reducing, ultrafiltered water throughout an entire restaurant or house. The multi-bore ultrafilter reduces 99.999% of solids and substantially reduces microbiological contaminates. Because the carbon cartridge follows the ultrafilter, it does not clog, resulting in higher taste and odor reduction levels. The final technology reduces 96% to 98% of lime scale without using chemicals or wasting water.

Pump & Play

Finding potable water can be a difficult task for rural communities in sub-Saharan Africa. South African nongovernmental organization Roundabout Water Solutions (RWSSA) found an innovative method for communities to pump and store clean drinking water: playground equipment that doubles as a pumping apparatus. Raissa Rocha, editorial intern at Water Quality Products, recently checked in with Sandra Hayes, administrative and donor relations manager at RWSSA, to discuss the systems and the organization’s efforts.
