Contaminant Maps by County
These county reports show the average concentrations of contaminants found in private well water samples tested by the North Carolina State Laboratory of Public Health from 1998-2010. County averages provide a useful way to observe an overall trend in a county, but are not detailed enough to predict the specific groundwater concentrations of contaminants in smaller regions and may not reflect the quality of groundwater in a single well. Private well data does not include monitoring wells or surface water samples collected by other state agencies.
