Book Reconnaissance Level Assessment of Water Quality Near Flandreau South Dakota

This book was released on 2002 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents water-quality data that have been compiled and collected for a reconnaissance- level assessment of water quality near Flandreau, South Dakota. The investigation was initiated as a cooperative effort between the U.S. Geological Survey and the Flandreau Santee Sioux Tribe. Members of the Flandreau Santee Sioux Tribe have expressed concern that Tribal members residing in the city of Flandreau experience more health problems than the general population in the surrounding area. Prior to December 2000, water for the city of Flandreau was supplied by wells completed in the Big Sioux aquifer within the city of Flandreau. After December 2000, water for the city of Flandreau was supplied by the Big Sioux Community Water System from wells completed in the Big Sioux aquifer along the Big Sioux River near Egan, about 8 river miles downstream of Flandreau. There is some concern that the public and private water supplies provided by wells completed in the Big Sioux aquifer near the Big Sioux River may contain chemicals that contribute to the health problems. Data compiled from other investigations provide information about the water quality of the Big Sioux River and the Big Sioux aquifer in the Flandreau area from 1978 through 2001. The median, minimum, and maximum values are presented for fecal bacteria, nitrate, arsenic, and atrazine. Nitrate concentrations of water from Flandreau public-supply wells occasionally exceeded the Maximum Contaminant Level of 10 milligrams per liter for public drinking water.

Book Assessing Aquifer Vulnerability to Contamination on the Pine Ridge Indian Reservation in Southwestern South Dakota

Download or read book Assessing Aquifer Vulnerability to Contamination on the Pine Ridge Indian Reservation in Southwestern South Dakota written by Lilly Jones and published by . This book was released on 2021 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ensemble model predicts that, relative to other locations in the study area, 37% of the reservation has a low intrinsic susceptibility, 42% was rated at a moderate level of intrinsic susceptibility, and 21% area was rated as having high intrinsic susceptibility. Fuzzy methods were employed to assess the certainty of these classes with the result that cells classified as having high intrinsic susceptibility are 90% certain, while low ratings are 80% certain. Geographically, the most sensitive locations in the study area include the Sand Hills area, much of the alluvial aquifer along the White River, and portions of the White River Badlands. The ensemble model compared well against an existing dataset of arsenic measurements in reservation wells and against a predictive model for nitrate. Sensitivity analysis was also completed. The most sensitive models in the ensemble stack are the USGS DRASTIC 2014 model and the 2018 standard DRASTIC model. The least sensitive model was the DRASTIC 2018 agricultural model. A discussion of uncertainty in environmental modeling and recommendations for resource management and further study were completed for this project. This project highlights the urgent need to collect and manage data on the Pine Ridge Indian Reservation so that the natural resource needs of tribal communities can be investigated and protected.
