Well water testing results and information posted

Monday, May 4, 2015 - 12:00am

The N.C. Department of Environment and Natural Resources (DENR) has posted the results of well testing conducted earlier this year as part of a program to test wells near coal ash ponds throughout the state.

You may view a summary of wells tested as of the date indicated here. You may view the raw data from the first round of well water testing here, which has an accompanying notes page here.  Additional groundwater information in regard to coal ash can be found on the department’s well water testing page.

This well testing is part of groundwater assessments being conducted in accordance with the Coal Ash Management Act of 2014. DENR has required that Duke Energy pay for the testing of all water supply wells near each of the utility's 14 coal-fired electrical generating facility boundaries. 
The test results are being used to inform well owners about the quality of the water they are using, health risks and treatment options. This investigation is being used to guide the successful closure of the coal ash basins as directed by the Coal Ash Management Act of 2014.

The first round of testing is being conducted for people who use private water supply wells and public drinking water supply wells within 1,000 feet of a coal ash storage pond. Subsequent testing will be conducted farther away from the coal ash ponds, as necessary. Well owners are able to choose from a selection of state-certified laboratories to sample water from their wells. All well testing conducted under the Coal Ash Management Act will be paid for by Duke Energy.

Many constituents that were tested in the public and private drinking water wells may be naturally occurring or unrelated to coal ash ponds.

Groundwater samples from supply wells are being collected and tested for constituents associated with coal ash, including: aluminum, antimony, arsenic, barium, beryllium, boron, cadmium, calcium, cobalt, total chromium, hexavalent chromium, copper, iron, lead, magnesium, manganese, molybdenum, mercury, nickel, potassium, selenium, sodium, strontium, thallium, vanadium, zinc, chloride, sulfate, pH, alkalinity, bicarbonate, carbonate, and total dissolved solids.
