What BOW is doing to address PFAS in waters of the State
DHEC has developed and is implementing three strategies for assessing PFAS in the state's waters. Contact information for each strategy is provided below. Please visit the associated pages for additional information.

UCMR5 – Drinking Water
Consistent with EPA’s PFAS Strategic Roadmap, UCMR 5 will provide new data that EPA has determined are critically needed to improve their understanding of the frequency and level at which 29 PFAS (and lithium) are found in the nation’s drinking water systems. Once per calendar quarter for four consecutive quarters, BOW will sample and analyze all public water systems that serve more than 10,000 persons and some small systems that will be selected by EPA for the designated 29 PFAS analytes (and lithium). UCMR5 is scheduled by EPA for national implementation in 2023-25.
What EPA is Doing About Drinking Water
EPA is addressing PFAS nationally from different perspectives (e.g., drinking water, ambient surface water, wastewater, solid waste management, remedial cleanup/corrective action, and product manufacturing information) as discussed here and in the links presented below.
- In February 2019, EPA published their PFAS Action Plan; it was updated in February 2020.
- On April 27, 2021, EPA established the EPA Council on PFAS (ECP). This Council is charged with building on the agency's ongoing work to better understand and ultimately reduce the potential risks caused by these chemicals.
- On October 18, 2021, EPA announced the Agency's comprehensive Strategic Roadmap to confront PFAS contamination nationwide (pdf version here).
- On June 15, 2022, EPA:
- Issued interim updated drinking water health advisories for PFOA and PFOS.
- Issued final health advisories for GenX and PFBS.
Details of EPA’s process and decisions regarding these updated and new HAs can be found here.
