The Delaware Department of Natural Resources and Environmental Control, in coordination with the Division of Public Health, has conducted sampling of more than 140 public water systems statewide to survey for a group of chemicals known as PFAS.
Two systems were near the health advisory limit of 70 parts per trillion: Bethany Crest in Sussex County showed levels at the limit, and Byler’s Country Market and Grocery Outlet in west Dover had PFAS above the limit.
At Bethany Crest, an existing exchange treatment had already been in place for nitrates and was found to be successful in decreasing the contaminants. A follow-up at Byler’s showed that, while classified as a public water system, the water is not used for consumption at the store.
An investigation to determine the source of PFAS at both locations is ongoing by DNREC.
