Additional well testing underway

Friday, May 29, 2015 - 12:00 am

While the first round of testing is underway 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 is underway for residents within 1,500 feet of a coal ash storage pond. Well owners are contacted by 3rd party state-certified laboratories to sample water from their wells.

Testing is also underway for wells earlier tested that were recommended for retesting.

Test results and updated summaries were posted May 19th and additional updates will be posted approximately every 2 weeks.

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.

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 and retested where necessary, 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.
