From the Introduction:
One of the primary environmental problems related to coal recovery in the Denver Basin is the potential effect on groundwater quality and quantity. This report presents the results of a water well inventory and sample program in four selected areas known to contain strippable coal and lignite deposits. The investigation was conducted during the summer and fall of 1979.
Baseline data is presented on water quality and water levels in wells in four areas likely to experience future coal or lignite surface mining. Areas in which water samples were collected include the Watkins, West Bijou Creek, Keenesburg, and Matheson areas. All samples were analyzed for specific conductance, pH, temperature, calcium, magnesium, potassium, silica, sodium, phosphorous, chloride, fluoride, sulfate nitrite and nitrate, iron, manganese, hardness, and alkalinity.
