State-specific guide and lab pathway.
Repeat testing
Guidance in view
Pennsylvania does not publish a single universal PFAS retesting cadence for all private wells in Sharp v1. Keep repeat testing tied to accredited-lab interpretation, Pennsylvania agency guidance, and any site-specific investigation follow-up.
Benchmark notes
Reference-based
Pennsylvania private wells are owner-managed, not regulated public-water systems. Pennsylvania's PFAS MCL rule can supply reference context for covered analytes, but private-well outputs should stay reference-based and should not be framed as compliance findings.

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.
Notes

Interpretation context

  • Pennsylvania does not publish a single universal PFAS retesting cadence for all private wells in Sharp v1. Keep repeat testing tied to accredited-lab interpretation, Pennsylvania agency guidance, and any site-specific investigation follow-up.
  • Pennsylvania private wells are owner-managed, not regulated public-water systems. Pennsylvania's PFAS MCL rule can supply reference context for covered analytes, but private-well outputs should stay reference-based and should not be framed as compliance findings.

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.

State reference context

Pennsylvania PFAS MCL rule used as private-well reference context

Pennsylvania adopted PFAS MCLs for PFOA and PFOS in public water, while private wells remain owner-managed. For Sharp v1, Pennsylvania can provide direct numeric reference context for covered analytes, but the route should still keep current state and federal transition notes visible and avoid presenting a private-well compliance determination.

Pennsylvania MCL for PFOA
14 ppt (Pennsylvania's PFAS MCL rule set PFOA at 14 ppt for public-water compliance context.)
Pennsylvania MCL for PFOS
18 ppt (Pennsylvania's PFAS MCL rule set PFOS at 18 ppt for public-water compliance context.)
