PFAS test results for Jones Industrial Park (Thurston County, WA)
PFAS above Washington’s state action level
Jones Industrial Park detected PFAS in 1 of its 2 tested water sources, with at least one result above Washington’s state action level (latest test August 2025).
Non-transient non-community system serving Thurston County · 9 connections · about 50 people.
At least one individual sample measured at or above a federal MCL value (4 ng/L for PFOA/PFOS; 10 ng/L for PFHxS, PFNA, HFPO-DA). Compliance with the federal standard is judged on running annual averages at the tap — a single source sample at that level is a flag, not a violation.

What this means
A Washington state action level (SAL) is the concentration at which the state requires a water system to notify its customers and take action — typically treating the affected source, blending it, or taking it offline. PFAS was detected in 1 of the 2 sources tested for this system, and at least one result was above a SAL. Ask the utility what it has done with the affected source since the sample date — the table above shows which sources were affected.
For PFAS at the drinking tap, the fix we plan to offer is under-sink reverse osmosis — manufacturer test data shows RO membranes reduce PFAS. See the planned systems.
These results describe the water system’s sources (wells, intakes), not any individual tap — utilities blend, treat, and rotate sources.
