Triangle Area Water Supply Monitoring Project, North Carolina

Abstract

Introduction Rivers and surface-water reservoirs supply drinking water to most residents throughout the Triangle area in North Carolina. These drinking-water supplies may be at risk because of rapid and continued land use change throughout the region. In partnership with the U.S. Geological Survey, several Triangle-area municipalities established a long-term water-quality and streamflow monitoring program to quantify changes in water quality and water availability over time and to evaluate the relative risk of potential contaminants in these drinking-water sources.
