About PFAS contamination in Oscoda
## Summary Oscoda Township's public water system has earned a Grade A for PFAS contamination, meaning the system is currently meeting federal drinking water standards. While testing detected 15 different PFAS compounds in the water supply, none of the chemicals with established federal limits — including PFOS, which carries an EPA maximum of 4 parts per trillion — had concentrations reported above those thresholds. The contamination source is known: PFAS chemicals have been traced to firefighting foam used at the former Wurtsmith Air Force Base.
## What the data shows Testing identified 15 PFAS compounds in Oscoda Township's water system. Of those, 14 — including compounds such as PFDA, PFOS precursors, and several fluorinated sulfonic acids — currently have no federal concentration limits established, meaning no legal benchmark exists against which to measure them. PFOS, the one compound in this dataset with a federal limit of 4 parts per trillion, did not have a concentration reported that exceeded that standard. The Grade A reflects compliance with existing federal rules, though the presence of multiple unregulated compounds is part of the public record.
## What residents should know Oscoda has a documented history of PFAS contamination linked to Wurtsmith Air Force Base, where aqueous film-forming foam (AFFF) was used for decades, and Department of Defense remediation efforts are ongoing. Residents who may be eligible for compensation should look into the 3M settlement, which covers communities affected by AFFF-related contamination. For the most current testing results and any updates to water treatment measures, residents should contact Oscoda Township's water utility directly.
About this summary: Narrative text on this page was drafted by an AI model (claude-sonnet-4-6) from EPA UCMR 5 data and reviewed before publication. The numeric data above is reported by water utilities directly to the EPA. If you spot an error, email data@checkyourwater.org.
What Oscoda residents can do
Oscoda's water meets federal PFAS standards based on EPA UCMR 5 testing. To stay informed:
- Read your utility's annual Consumer Confidence Report (CCR) — request a copy if you don't receive one.
- Sign up for water quality alerts from your utility.
- If you're on a private well, get it independently tested for PFAS.
- Reduce PFAS exposure from non-water sources: avoid non-stick cookware, stain-resistant fabrics, and grease-resistant food packaging.
Primary contamination source: Wurtsmith Air Force Base AFFF firefighting foam
Settlement information: Ongoing DoD remediation; 3M settlement eligible
