Questions
Frequently asked questions
Is Fort Lewis tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Fort Lewis, PFOS 11.1 ng/L and PFOA 6.8 ng/L were measured above the 4 ng/L federal limit in EPA's 2024 testing. JBLM Lewis (PWSID WA5326050) has a Purity Score of 57/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
Who provides tap water in Fort Lewis?
JBLM Lewis (PWS ID WA5326050) is the public water system on record for Fort Lewis, Washington, serving about 35,414 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Fort Lewis get its drinking water?
Groundwater (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Fort Lewis's water?
Yes. In EPA's UCMR 5 testing (2023-04-12 to 2024-10-08), PFOS was measured at 11.1 ng/L against a 4 ng/L federal limit and PFOA was measured at 6.8 ng/L against a 4 ng/L federal limit. PFBS (5.4 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxS (8.8 ng/L, below the 10 ng/L federal limit) were also detected. PFPeA (3.1 ng/L) was also detected; it has no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Fort Lewis's tap water?
Lead is not in Fort Lewis's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
What does the latest Fort Lewis water report show?
PurityMap's current record for Fort Lewis holds 31 findings: 2 above a reference, 2 detected within the reference, 1 detected with no limit and 26 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
