DHEC: Mount Pleasant water tests show no presence of pesticides

A third-party contracted by the South Carolina Department of Health and Environmental Control reports water samples collected in Mount Pleasant last week show no presence of pesticides or "other tested compounds."

DHEC samples were taken from three homes officials with Mount Pleasant Waterworks said they chose because of recent concerns.

Those living in several areas of Mount Pleasant have been publicly questioning their water quality after a string of cancer diagnoses. In response to initial concerns in June, DHEC said data and reports did not indicate the presence of a cancer cluster, but said it would be taking concerns over water quality seriously.

The results may be comforting to many in the area, some who began using at-home water quality test kits and saw unwanted results. At an impromptu Sunday morning press conference, MPW general manager Clay Duffie fielded questions from people concerned about what they had seen on social media about at-home tests taken in the area.

The EPA has since confirmed it does not endorse, support or regulate those who manufacture at-home water quality tests. Duffie argued at-home tests are not recognized as official sampling results and promised MPW would work with DHEC on checking the water in the area.

But while some may find comfort in the results, others are likely still looking for closure.

A man who lives in Mount Pleasant's Dunes West community sent a sample of his drinking water to Charleston-based GEL Laboratory for testing on July 14. When he received the results July 17, he said he was concerned.

The man, who has asked to remain anonymous, told ABC News 4 he sent one sample to the local lab to test for 25 perfluorinated chemicals (PFCs) that he believed Mount Pleasant Waterworks did not test for.

His results showed 12 out of 25 were detected, including perfluoro-2-propoxypropanoic acid (PFPrOPrA). According to the EPA, the substance, produced by DuPont, is commonly known as GenX.

Duffie added that GenX is an emerging contaminant with no maximum safe level set currently by the Environmental Protection Agency. We’ve reached out to the EPA for comment but have not heard back yet.
