Well Contamination

May 11, 2011--New study reveals dangerous levels of flammable methane in drinking water wells (Colorado Independent)

A new scientific study conducted by researchers at Duke University for the first time shows drinking water wells closer to natural gas drilling activity contain higher levels of flammable methane gas that the federal government says could require “hazard mitigation” action.


February 23, 2010--Road salt melts snow, but it contaminates groundwater and damages habitats (Washington Post)

We toss more than 20 million tons of sodium chloride on our roadways every winter. That's about 13 times more salt than is used by the entire food processing industry. Salt lowers the freezing temperature of water and thus melts street-clogging snow and ice.


January 10, 2010--Water: Gas companies helped create a map of nontributary water (Durango Herald)

Most coalbed methane wells in Southwest Colorado do not deplete area rivers, a state regulator has decreed. But ranchers say the decision gives away water to gas companies at the expense of senior water rights owners. State Engineer Dick Wolfe finished new rules for area coalbed methane wells Dec. 30.


September 18, 2009--Health ills abound as farm runoff fouls wells (New York Times)

Runoff from all but the largest farms is essentially unregulated by many of the federal laws intended to prevent pollution and protect drinking water sources. The Clean Water Act of 1972 largely regulates only chemicals or contaminants that move through pipes or ditches, which means it does not typically apply to waste that is sprayed on a field and seeps into groundwater.
