Nitrate-Nitrogen Levels in Well Water from the Little River/Rooty Creek Watershed in East Central Georgia

The 99,912 ha Little River/Rooty Creek watershed lies in the heart of Georgia's dairy industry. Surface and ground water contamination from agricultural activities is of great concern in the watershed. This study shows that ground water quality in the watershed is not generally affected by nitrate-nitrogen (nitrate-N) from typical nonpoint sources. However, there are nitrate-N "hotspots", primarily around dairies, that exceed the EPA's Maximum Contaminant Level (MCL) for nitrate-N in drinking water. Farmers with high nitrate-N levels in their well water should complete the Farm*A*Syst worksheets, implement the recommended wellhead protection measures and use Best Management Practices to control and prevent ground water contamination.
