We are proud to report that no contaminants monitored under the Safe Drinking Water Act requirements were detected at levels that violated state and federal drinking water standards.

Per- and polyfluoroalkyl substances (PFAS)
In addition to the contaminants that are tracked and measured under the Safe Drinking Water Act, the city also is monitoring levels of PFAS in the water system.
The 3M Company made PFAS at its Cottage Grove facility from the late 1940s until 2002. PFAS wastes were disposed of at multiple sites in Washington County. The source of the PFAS in Woodbury's groundwater has been identified as these disposal sites.
The Minnesota Department of Health (MDH) has established health standards for specific PFAS parameters and has issued health risk advisories on seven of Woodbury's 19 wells since 2017.
The city removed all seven of these wells from service, and constructed a temporary water treatment facility near the intersection of Valley Creek Road and Tower Drive that brought four of these wells back into service in summer 2020. 3M and the State of Minnesota funded the construction of the temporary facility.
The water delivered to customers continues to meet all state and federal water quality standards and guidelines for PFAS.
"Unlike other chemicals, PFAS monitoring is not currently required as part of the Safe Drinking Water Act," Westerman explained. "However, MDH has been monitoring City of Woodbury municipal wells for PFAS since the early 2000s, and we've continued to update the public about changes in the PFAS testing results and as part of this annual drinking water report."

The state is expected to announce its long-term plan for addressing PFAS in the east metro water supply this summer. Details will be provided on the city's website and in upcoming editions of the City Update newsletter. Residents who have questions about their private water supply should contact MDH.
