Groundwater Atlas for pesticides
The recently published Groundwater Atlas for pesticides provides an overview of where and when pesticides have been found in groundwater. The results can be used to improve water quality in the Netherlands. The data will be used by the Board for the Authorisation of Plant Protection Products and Biocides (Ctgb) to monitor groundwater quality. The Groundwater Atlas was developed between 2015 ...

EPA to fund monitoring of groundwater wells at California pesticide dump
The U.S. Environmental Protection Agency is asking for public comment on a proposed agreement with Target Corporation to allow for redevelopment of land adjacent to the Frontier Fertilizer Superfund site. Under this agreement, Target Corporation, with EPA oversight, will fund and perform movement of eight groundwater monitoring wells at privately-owned parcels lying to the north and west of the ...

Pesticides persist in groundwater, say SSSA
Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations. The downward movement of pesticide degradation products, formed in situ, can also contribute to the contamination of ground water. Once in ground water, pesticides and ...

Encouraging results in evaluating groundwater contaminants
The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

Pesticide pollution slow to reach groundwater
Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped. Groundwater is found underground in absorbent layers of rock. ...

Pesticide impact: comparing lab, field-scale results
Assessing the environmental risk of pesticide use is an important, complex task that requires knowledge of the equilibrium sorption parameter. This helps researchers assess the risk of pesticides leaching into groundwater. For cost-effective assessments, this is usually determined through batch experiments that find the amount of pesticide in test soils as a function of concentration at a ...

NRDC exposes EHS programs slashed under Bush Administration
Millions of Americans have been left in the dark about hazardous pollutants being released into their communities, according to a new report by the Natural Resources Defense Council (NRDC). The new report provides a comprehensive look at the Bush Administration’s systemic cutting of health and environmental programs that monitor toxins across America. “The Bush administration has turned off the ...
