Phase III Hydrogeologic Characterization for the Mamm Creek Field Area
The Phase III Hydrogeologic Study of the Mamm Creek Area is a continuation of the Phase I and Phase II studies for the same area in Garfield County. The objective of the Phase III study was to gather additional data to clarify the nature of the hydrologic flow system and water quality in the study area, including evaluating the possible effects, if any, of oil and gas development on the Wasatch Formation water quality.
Three pairs of nested groundwater monitoring wells were installed to facilitate collection of data for the evaluation of three-dimensional hydrologic flow system and water quality in the Mamm Creek study area to assist in achieving these objectives. Four sets of groundwater samples were collected in 2011 and 2012. Data obtained during this investigation was also used to further evaluate the results of the Phase I and Phase II hydrogeologic studies performed in this area.
