Lewes, Delaware- December 14, 2021- Lewes Board of Public Works is pleased to announce the results of recent potable water testing program for polyfluoroalkyl substances (PFAS). The testing was voluntarily conducted in cooperation with the Delaware Department of Natural Resources and Environmental Control, along with the Division of Public Health (DPH) and the Office of Drinking Water.
PFAS are manmade, widely used, long lasting chemical components which break down very slowly over time. PFAS can be found in common household and industrial items and over time find their way into water, air, and soil. Worrisome levels of PFAS are now showing up in many community drinking water supplies.
The EPA has issued a Health Advisory Level for two PFAS compounds in drinking water: perfluorooctanoic acid (PFOA) and perfluorooctanoic sulfonate (PFOS). The State of Delaware has identified 70 parts per trillion (ppt) as the maximum allowable level for these contaminants, in compliance with EPA standards. The BPW’s high quality groundwater sources tested well below those levels to an exceedingly low level of 3.13ppt and 1.89 ppt for PFOS and PFOA, respectively.
Lewes Board of Public Works is committed to providing the Lewes community with high quality water from our deep wells. To that end, defending the well recharge areas remains an important priority for the BPW. Recent efforts to protect the well recharge areas include the BPW’s participation in the purchase of the Jones Farm at the corner of Kings Highway and Clay Road, which is a property located adjacent to the BPW well field and entirely within a major recharge area.
