Session Law 2014- 122, the North Carolina Department of Enyiromnent and Natural Resources (DENR):requested that, at a minimum, all water supply wells within 1,000 feet of each coal ash waste facility?s boundary be sampled. . . On August 17, 2015, Pace Analytical Services, Inc. collected groundwater samples from 1 well(s) on the referenced property. The? water samples were collected and analyzed for constituents that may be associated with coal ash. A complete copy of the laboratory sample results aregattached for your review. The table below provides a comparison of the lab results with the groundwater standards. North Carolina?s groundwater standards are Calculated topprotect your groundwater as a source of drinking water. Thestandards prohibit contamination that would create athreat to human health.

This means that studies have estimated theiripotential impact to human ,healthi?but that a groundWater standard has. not been established. For a discussion of any of these constituents that are in?yoiur well, see your Health Risk Evaluation provided by the N.C. Departinent of Health and Human Services. a 1611 Mail Service Center.

It should also be noted that many of the constituents that were tested may be naturally occurring andfor unrelated to coal ash ponds. Work is currently underway to determine their source and extent. If DENR determines that groundwater standards in your well have been exceeded and that a coal ash pond is the source, state law requires that the utility provide you with an alternative water supply. The, Division of Public Health, Epidemiology Section, Occupational and Environmental Epidemiology Branch (OEEB) has evaluated A the well sample results. DHHS has provided?the attached Health Risk Evaluation for the. sample results ?'om each well(s) sampled at the referenced property. . If your attached Health Risk Evaluation includes a recommendation that your water not be used for drinking or cooking, please note that the recommendation-was made using a statistical risk threshold of one additional case of cancer in a population of 1 million people who were eXposed at thatlevel over a lifetime. For non-cancer health effects, DHHS relied on a daily lifetime exposure, limit. It is also impertant to recognize that your well water has been deterrnined to meet all the criteria of the federal Safe Drinking Water Act for public drinking water. We understand?the importance or this matter. toan ad also the complexity of this letter. We, together with DHHS, are available to discuss the results and meet with you to answer any questions to assure that all of this information is explained clearly and completely.
