GE and SI will collect the contaminated liquid waste and send it off site for disposal
The U.S. Environmental Protection Agency (EPA) announced Wednesday that it has reached an agreement with the General Electric Co. (GE) and SI Group Inc. (formerly Schenectady Chemical) to collect and properly dispose of contaminated groundwater and liquid leaching from the Dewey Loeffel landfill that is threatening several nearby drinking water wells.
Recently, the U.S. Environmental Protection Agency (EPA) announced it had worked with three New Jersey school districts to successfully lower lead levels in their drinking water. Testing in 2010 and 2011 found elevated lead levels in approximately 8% of the outlets it tested at the Atlantic City, Union City and Weehawken school districts. The districts resolved the problem through a variety of methods, from filtration to replacing fixtures to simply shutting off those outlets. The latest round of testing showed that lead levels were within acceptable EPA limits.
The 360 single tank aeration filter features Clearion controls for forward and reverse motor capability, and can replenish its Oxy Chamber each night without having to backwash, saving hundreds of gallons of water per week. Fully adjustable cycles, along with Vortech tank technology, ensure the media bed is backwashed to the fullest and leaves no collected iron or sulfur contaminants.
In December, the U.S. Environmental Protection Agency (EPA), the National Institutes of Health and the Food and Drug Administration announced that as a part of a collaboration, a new high-speed robotic screening system would begin testing a library of 10,000 compounds for potential toxicity.
Lead has been a hot topic for consumers and the media for many years. We all have heard about the deterioration of U.S. water distribution systems, lead service lines, extremely high levels of lead in Washington, D.C.’s drinking water because of a change from chlorine to chloramine, lead in paint, lead in toys, new lead content laws in California and Vermont (soon to be national)—concerns about lead that will never go away.
Challenges in creating a consistent lead certification protocol
The U.S. Geological Survey (USGS) released a report in August revealing that 20% of untreated water samples from wells across the U.S. contain concentrations of trace elements exceeding human health benchmarks. Raissa Rocha, editorial intern for Water Quality Products, spoke with Joe Ayotte, USGS hydrologist and lead author of the study, about the report and the occurrence of trace elements in groundwater.
Raissa Rocha: What was the purpose of this study?
In recent days, groundwater has been gaining attention. Increased hydraulic fracturing operations have caused controversy over potential methane gas contamination. Reports indicate that groundwater aquifers, especially in the drought-prone southwestern U.S., are being depleted more quickly than they can be recharged. Surveys, like the one recently released by the U.S. Geological Survey (USGS), reveal that contaminants such as arsenic are widespread in the nation’s water wells.
In July 2011, the California Department of Toxic Substance Control (DTSC) issued its first annual report on plumbing products sampled and tested for lead concentrations in 2010. All drinking water faucets that were sampled and tested were reported to comply with the state’s new low-lead law.

Many adverse ecological effects have been attributed to pharmaceutical and personal care products (PPCPs) and endocrine-disrupting compounds (EDCs), but it is not clear what risk they pose to human health. In the past, water was known to contain these chemicals, but the exact amount was difficult to quantify. Recently, these chemicals have gained much more attention.
Treatment solutions for chemicals affecting human health
When the McGraw Hill Data Center in East Windsor, N.J., was being built, the local municipal authority informed the company that it did not have the capacity to support the makeup water for the data center’s condensers or chill water plant. A new well was drilled to serve the plant; however, the groundwater supply had iron and manganese levels that exceeded regulatory limits.
