Overview

The US Geological Survey (USGS) has cooperated with the State of Georgia to monitor water quality throughout the State since 1937. The current Statewide Water-quality Montoring Program is a network of 50 stations across Georgia operated in cooperation with the Environmental Protection Division of the Georgia Department of Natural Resources (GAEPD). Over the years, the temporal and spatial design of this Program has resulted in the creation of a suite of long-term water-quality data that have been collected during a wide variety of hydrologic conditions at over 800 stations across the State. These data, which are maintained long-term by the USGS in the National Water Information System (NWIS) and are readily available via NWIS-Web (waterdata.usgs.gov/ga/nwis/qw), are collected using approved USGS methods and represent the entire range of basin characteristics across all the physiographic provinces in Georgia.
