On October 10, 2012, the U.S. Environmental Protection Agency (EPA) released a follow-up to its initial report on its Pavillion Wyoming groundwater investigation involving the first documented correlation between
groundwater contamination and hydraulic fracturing for natural gas. Titled, Investigation of Ground Water Contamination near
Pavillion, Wyoming: Phase V Sampling Event Summary of Methods and Results (2012), and according to the fourteen page report, available here,
[t]he objective of the Phase V component of the Pavillion, Wyoming ground water investigation was to resample and reanalyze EPA’s two deep monitoring wells (MW01 and MW02) in conjunction with the U.S. Geological Survey. The EPA also collected samples from five (5) domestic water wells located adjacent to the deep monitoring wells and a municipal well. Below, this “Summary of Methods and Results” details the methods, results, and QA/QC for the Phase V investigation.
