The City of Dayton Department of Water continues to monitor water quality, partner with regulatory agencies, and research strategies for the protection and treatment of your drinking water. Taking these efforts ensures we remain at the forefront of protecting public health and our environment.

On April 10, 2024, the U.S. EPA issued new regulations regarding PFAS in drinking water. These new regulations include Maximum Contaminant Levels (MCLs) of 4 parts per trillion (ppt) for two PFAS compounds, PFOA and PFOS, and 10 ppt for PFHxS, PFNA, and HFPO-DA (commonly known as GenX chemicals) in drinking water. All public water systems have five years to come into compliance with the new regulations, and Dayton is ahead of many other water utilities.

To date, Dayton has expanded our monitoring well network, enhanced our analytical capabilities, removed contaminated wells, and are currently working with industry experts to respond to this threat to our drinking water. In addition, we are working with the U.S. EPA Office of Research and Development to develop a pilot project for removing these contaminants at our treatment plant.

In addition, the City of Dayton has received support from the Ohio EPA for PFAS-related projects to reduce the PFAS level in our drinking water. Funding earmarked by the Ohio EPA can be found on page 30 in the 2023 Program Management Plan (PMP) DWAF-PMP-2023.pdf (ohio.gov) and page 28 in the 2024 PMP DWAF-PMP-2024.pdf (ohio.gov) for listings of Dayton’s projects. These loans are 0% interest and principal forgiveness. Thus, these projects will not affect water rates.

Dayton continues to seek funding opportunities to address PFAS, including ongoing litigation to have the remediation costs covered by the PFAS manufacturers and other responsible parties instead of our customers.
