County PFAS Samples Well Below Health Advisory Level

DAYTON, Ohio (Sept. 22, 2021) – Montgomery County Environmental Services (MCES) contracted with PACE Analytical, an Environmental Protection Agency-certified company, to test the drinking water distributed by the county. In total, water samples from 13 locations across the county were collected last month and sent to an Ohio EPA-approved testing laboratory.

 

MCES received results from those sampling efforts. Of the many compounds which make up per- and polyfluoroalkyl substances (PFAS), the two that are of particular interest were perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). For PFOS and PFOA, Ohio EPA Action Levels indicate that the compounds must either be individually below, or below a combined result, of 70 parts per trillion (ppt), in order to be below the Health Advisory Level (HAL). The 13 samples tested had well below the HAL guidance, showing only scant traces of PFAS that ranged from Non-Detect to 10.9 ppt.

 

“We are pleased to see that our results returned so far below the HAL because we want our water customers to know that our water is safe to drink,” said Montgomery County Administrator Michael Colbert. “Even before we facilitated the water testing, we truly believed the PFAS levels were below the HAL recommended 70 ppt. If we thought otherwise, we would have alerted our water customers that we had some reservations about its safety and to stop drinking it. But being able to see the data resulting from the tests allows us to provide customers with scientific proof showing the water is safe to drink.”

 

Montgomery County has made water quality one of our highest priorities. The County conducted research to determine the best way to test the water and developed a sampling plan. It then shared the plan with the City of Dayton, Greene County, as well as the Ohio and US EPAs. After MCES received constructive feedback, the plan rolled into action in August.

 

“We drink County water. Our children and family members drink our water, and we distribute water to our neighbors in Greene County. We believe it is our duty to ensure the health and safety of our residents,” said Matt Hilliard, Director of Environmental Services. “The data is something we had been lacking and I’m glad we decided to conduct our own testing to see the results for ourselves. We needed to have this testing completed, and we are so proud to report that we received these results.”

MCES vowed transparency with the testing results and has also shared the data with the City of Dayton, Greene County, Ohio and U.S. EPAs. Montgomery County plans to continue testing the water distribution system annually. For more information, please go to our website www.mcohio.org.
