Monitoring Of Groundwater Levels And Surface-Water Quality At The South Well Field, Franklin County, Ohio

Science Center Objects

The City of Columbus operates 5 high-capacity collector wells to extract groundwater for drinking-water supply. To assist the City, the USGS monitors water levels in 5 observation wells and operates a water-quality monitor on the Scioto River where specific conductance, temperature, dissolved oxygen, pH, and turbidity are measured on an hourly basis. In addition, groundwater-level synoptic measurements and streamflow gain/loss studies are done every 3 to 4 years.
