Compliance

0health-based violations in the last 10 years

From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

Not in this recordDisinfection by-products weren't monitored in this dataset

No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.

A federal limit (an MCL or action level) is an enforceable legal cap; a health goal is often stricter. Meeting the limit is a compliance fact, not a health clearance, and PurityMap publishes no overall compliance verdict.

What you can do

Test first, then treat what was found

    Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.

Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Questions

Frequently asked questions

Who does WASILLA WATER SYSTEM serve?

WASILLA WATER SYSTEM (PWS ID AK2224646) is a public water system serving 18,492 people in Wasilla, Alaska.

Where does WASILLA WATER SYSTEM get its water?

WASILLA WATER SYSTEM is on record as drawing from groundwater. The source shapes which contaminants matter most for this system.

What does WASILLA WATER SYSTEM's monitoring record show?

PurityMap's record for WASILLA WATER SYSTEM holds 31 findings: 2 detected within the reference and 29 not detected, from 31 evidence records. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.

Is WASILLA WATER SYSTEM's water safe to drink?

PurityMap does not issue a safety verdict. It publishes WASILLA WATER SYSTEM's measured results against each contaminant's benchmark so you can read them in context. Safety depends on the specific finding, your plumbing, and how the water reaches your tap.

How current is this WASILLA WATER SYSTEM data?

The latest published record for WASILLA WATER SYSTEM is dated 2026-09-16. Utilities report on regulatory cycles, so results reflect the monitoring period rather than a live reading.

Does this assessment represent my home's tap water?

No. It is assessed at the water-system level from WASILLA WATER SYSTEM's own monitoring. It does not cover the service line to your building or the plumbing inside it, which can add lead and other metals after the water leaves the system. A tap test is the way to know what reaches your glass.

What contaminants were detected in WASILLA WATER SYSTEM?

Perfluorohexanesulfonic acid (PFHxS) and Lead (90th percentile) were detected in this record. Each finding shows its measured value, its reference and its source on this page.

What should I do if I'm concerned about PFAS in WASILLA WATER SYSTEM's water?

Start with what the record shows: the PFAS findings above list each measured value against its reference. This record cannot show your home's plumbing, so a tap test tells you what reaches your glass. If you decide to treat your water, look for a filter whose certification covers the specific PFAS compounds in your record; the section "Certified for a concern found here" lists only products with a current certification record for these concerns.

What should I do if I'm concerned about lead in WASILLA WATER SYSTEM's water?

Start with what the record shows: the lead findings above list each measured value against its reference. This record cannot show your home's plumbing, so a tap test tells you what reaches your glass. If you decide to treat your water, look for a filter whose certification covers the specific contaminant in your record; the section "Certified for a concern found here" lists only products with a current certification record for these concerns.
