Well Water Testing Map

N.C. Department of Environmental Quality staff have developed a map to display the location and results of well water testing conducted as part of the Coal Ash Management Act of 2014. The map is linked below and includes geographic locations of each well test result as well as any information when constituent(s) exceeded drinking water standards or health risk levels. Users may search by address, or use the drag and zoom functions to locate results. The map has available pop-up windows to find additional detailed results. Users can zoom into the area of interest and click on the map points for a pop-up window with more details.

Well Water Testing Information Chart

The well water testing chart provides totals and links to the detailed individual results at each well where state officials have conducted tests and confirmed that the well owners received the results. The chart includes totals from the mapping tool for:

  • Public Wells: Wells that provide drinking water to 15 connections or 25 or more people 60 or more days per year;
  • Private Wells: Drinking water well located on private property;
  • Well Totals: Respective total for the row of data;
  • Power Plant: Coal ash facility closest to the well;
  • Number of Wells: Number of wells identified for testing; and
  • Samples Taken: Number of total samples taken including retests.

Well identifications, or IDs, are assigned to properties as a whole and sometimes contain multiple wells on the same property under the same well ID. Therefore, the totals represent the number of unique well IDs and do not include the total number of individual wells. The chart is at:

Well Water Exceedance Information 

The following table shows the number of results for well IDs. The table displays results that exceed one or more thresholds for one or more parameters of either:

  • Federal MCL standards (drinking water standards),
  • State 02L standards (groundwater standards),
  • State 02L Interim Maximum Allowable Concentration thresholds for groundwater, or
  • Dept. of Health and Human Services’ health screening levels. 

Well IDs are assigned to properties as a whole and sometimes contain multiple wells on the same property under the same well ID. Therefore, the totals represent the number of unique well IDs and do not include the total number of individual wells. The exceedance information can be found at: http://www.ncwater.org/?page=607.
