Guidance in view
No single statewide PFAS retesting cadence is fixed in Sharp v1. Use EGLE or local health investigation context and official Michigan advice for follow-up timing.
Benchmark notes
Reference-based
Michigan uses state drinking water standards and official investigation context. Private well interpretation remains reference-based and should not be framed as legal compliance.

State guidance and lab route review date.
Private-well next action
Test first, then interpret against state guidance.
State-specific lab and sampling guidance should appear before any filter shopping or whole-house escalation.
Sampling and testing
What to do first
- Use the state-certified lab route rather than a generic home test suggestion.
- Follow the state sampling instructions before collecting a PFAS well sample.
- Keep interpretation reference-based and avoid calling a private well compliant or non-compliant.

Guide-defined next lanes
Keep private-well intent inside the action stack before shopping broadens.
This state page should hand off into a small number of high-intent guides that settle evidence order, certification logic, and ownership burden before a household drifts into generic PFAS browsing.
Evidence order
Should you test before buying a PFAS filter?
Start with test-first logic so the private-well route stays evidence-led before any product shortlist opens.
Private-well compare
Compare certified point-of-use after a well test
Open the compare lane only after the state route and test result are already interpretable.
Certification logic
Read NSF 53 vs 58 with the PFAS claim in view
Use the certification guide to keep badge shorthand from replacing exact model and claim review.
Ownership burden
Review annual cost before the treatment class grows
Keep recurring cost visible before a private-well household overbuys the wrong treatment class.
State reference context
Michigan PFAS drinking-water MCLs used with other private-well factors

Michigan MCL for PFOA
8 ppt (Useful reference context for private-well interpretation in Michigan.)
Michigan MCL for PFOS
16 ppt (Useful reference context for private-well interpretation in Michigan.)
Michigan MCL for PFNA
6 ppt (Michigan publishes seven PFAS MCLs.)
