Baseline Data: Pavillion, Wyoming Area Groundwater

Denke, Lisa
Groundwater contamination in Pavillion Gas Field, Fremont County, Wyoming was researched in order to determine if statistically significant changes in groundwater constituents have taken place. Baseline data from USGS Water Supply Papers published in 1959 and 1969 were compared to data published in the Environmental Protection Agency's 2011 report Draft Investigation of Ground Water Contamination near Pavillion, Wyoming, and also to data retrieved from EPA's FTP site. Gas wellbore construction was analyzed to identify communication paths between the gas reservoir and the overlying aquifer. Well construction histories and cement bond logs from the Wyoming Oil and Gas Conservation Commission website were analyzed to determine the level of cement fill behind pipe, and a cross section was constructed to show the data in a spatial reference frame.
