We reviewed water quality data made available by the Colorado Oil and Gas Conservation Commission for water wells in the Denver-Julesburg Basin in northeastern Colorado as a function of proximity to oil and gas wells. The likelihood of elevated concentrations of methane and certain inorganic constituents increased with proximity to oil and gas wells. Based on carbon-13 isotope abundance in the methane, the methane in water wells was mostly biogenic, not thermogenic. Based on the available data, the occurrence of water well contamination associated with oil and gas development is infrequent.
