Water Quality and Hydrogeology near Four Wastewater-Treatment Facilities in Grand211 Teton National Park and John D. Rockefeller, Jr. Memorial Parkway, Wyoming, 211 September 1988 through September 1997

摘要

This report descries the effect that four waste-water-treatment facilities211u001elocated near Moose Village, Signal Mountain, Colter Bay Village, and Flagg Ranch 211u001ehave on ground-water quality. Water-level measurements and the chemical quality 211u001eof the ground water are described and evaluated based on data collected from 1988-211u001e97 from 21 monitoring wells and 18 water-supply wells. Suggestions for 211u001emodifications to the existing monitoring-well networks also are included. The 211u001egeneral physiolography, geology, and hydrogeology of the study area are 211u001edescribed. Wastewater-treatment facility descriptions, hydrogeologic settings, 211u001eand water quality near the facilities also are presented. Water-level 211u001emeasurements and selected biologial and chemical-quality data collected in 211u001esamples from monitoring wells are used to evaluate the general water quality near 211u001ethe facilities. The report includes a regional water-table map that was 211u001econstructed as of part of another investigation of the study area, tables listing 211u001ewater-level measurements and water-quality data, schematics of generalized 211u001ehydrogeologic sections, and water-level measurements and water-quality data in 211u001esamples collected from selected water-supply wells located in the study area. 211u001eAvailable well-construction records and well logs describing the general 211u001elithology at selected monitoring wells are presented in appendices. Boxplots 211u001eshowing the variability of selected constituents in samples collected from two 211u001ewells at the Colter Bay Village wastewater-treatment facility are presented.
