The first of two public hearings is taking place Monday, July 14 on possible changes to Dayton’s drinking water protection program. Drinking water for more than 400,000 people in Montgomery and parts of Greene County comes from two wellfields that tap into the Great Miami Buried Valley Aquifer, a shallow sand and gravel aquifer that is vulnerable to contamination from surface spills.
A map from the EPA shows the original boundaries of the investigation in Riverside: Hypathia Avenue on the east, Rohrer Boulevard on the west, Guernsey Dell and Minnesota Avenues on the north and Valley Pike Street on the south. The investigation has since expanded by several blocks.
A problem with pollution in Riverside is more widespread than environmental protection officials originally thought. The U.S. Environmental Protection Agency has already inspected approximately 110 homes for toxic vapors, and found problems in more than half. In December WYSO reported the EPA would be testing dozens of homes after being contacted by the Ohio EPA to assist; the area to be inspected has since expanded by several blocks.
