Updated well water testing results and information posted

Wednesday, July 8, 2015 - 12:00am

The N.C. Department of Environment and Natural Resources, or DENR, updated through July 7, individual results from testing conducted at public and private water supply wells near Duke Energy’s 14 coal-fired electrical generating facility boundaries.

Spreadsheet updated
The updated spreadsheet provides a detailed account of the results at each individual well where tests have been conducted, and the state has confirmed that the well owners have received the results of those tests. The spreadsheet compares the individual results of testing for coal ash-related metals and constituents with state and federal water quality thresholds, if such a threshold exists. The spreadsheet includes an additional 58 results for wells tested since the previous spreadsheet was posted June 11. These specific well test results include 20 additional wells and 38 resampling results since the June 11 update.

Well test results summary updated
DENR also updated its summary of well test results through July 7. The summary of well test results includes information on 27 additional wells since the June 11 report. The summary includes all results sent back to DENR, whereas the spreadsheet includes only results where well owner receipt has been confirmed. Thus, the summary numbers and the spreadsheet numbers are different.

Additionally, 42 resampling results have been reported for wells that previously received resample recommendations from the N.C. Department of Health and Human Services, or DHHS. These well results are listed on the spreadsheet in addition to the well’s original sample results and are identified with an “R” at the end of the identification of each well owner.

Health risk evaluations summary updated
DENR has updated the number of health risk evaluations that were produced by DHHS and sent them to homeowners along with the well test results. The updated summary includes information on 327 health risk evaluations that have been received by well owners.
