In January 1999, the U.S. Geological Survey began an expanded monitoring program near Deer Trail, Colorado, in cooperation with the Metro Wastewater Reclamation District and the North Kiowa Bijou Groundwater Management District. Monitoring components were biosolids, soils, crops, ground water, and streambed sediments. The monitoring program addresses concerns from the public about chemical effects from applications of biosolids to farmland in the Deer Trail, Colorado, area. Constituents of primary concern to the public are arsenic, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, selenium, zinc, plutonium, and gross alpha and beta activity and are included for all monitoring components. This report presents chemical data from the first year of the monitoring program, January–December 1999, for biosolids, soils, alluvial and bedrock ground water, and streambed sediments. The groundwater section of this report also includes climate data, lithologic descriptions, well-completion diagrams, water levels, summary statistics for the water-quality data, and results of statistical testing of selected data for trends and for exceedance of Colorado regulatory standards. Data in this report provide a geochemical baseline for each monitoring component prior to the planned water transfer in 2000 from the Lowry Landfill Superfund site to Metro Wastewater Reclamation District treatment facilities.
