EPA to Wyoming Residents Near Drilling Sites: Don't Drink Your Water

ProPublica:

EPA scientists began investigating Pavillion's water in 2008 after residents complained about foul smells, illness and discolored water, and after state agencies declined to investigate. Last August the EPA found contaminants in a quarter of samples taken during the first stage of its investigation, and the agency announced it would continue with another round of samples -- the set being disclosed now.

In the meeting Tuesday, the agency shared results from tests of 23 wells, 19 of which supply drinking water to residents. It found low levels of hydrocarbon compounds -- various substances that make up oil -- in 89 percent of the drinking water wells it tested. Methane gas was detected in seven of the wells and was determined to have come from the gas reservoir being tapped for energy. Eleven of the wells contained low levels of the compound 2-butoxyethanol phosphate -- a compound associated with drilling processes but that is also used as a fire retardant and a plasticizer.

The scientists also found extremely high levels of benzene, a carcinogen, and other compounds in groundwater samples taken near old drilling disposal pits. Some of the samples were taken less than 200 yards from drinking water sources and scientists expressed concerns that the contaminated water was connected to drinking water wells by an underground aquifer.
The EPA recommended that residents "avoid drinking water" and use house fans and ventilation while showering to "avoid explosion."

Can't wait to see what Carl Wimmer has to say about this one.
