Since the development of the oil and gas resources in the area, Pavillion residents have reported water, air and soil contamination and associated health impacts. In August 2009, the Environmental Protection Agency (EPA) publicly released data from their investigation of 39 drinking water wells in the Pavillion area. Eleven of those drinking water wells were significantly contaminated. The health information that was gathered from participants in this survey is compared to the known health effects of the chemicals that EPA reported were in these 11 drinking water wells. Survey results also include information as to other chemicals that are known to produce the health effects being reported by Pavillion community members.
