Perfluorooctanesulfonic acid
6.2ng/L
Each block = 4.0 ng/L federal MCL (2024)
Jackson Water Works & Sewer Board serves 11,715 people from surface water. 31 results are on record. PFOS is above its federal limit (a 2024 limit that water systems have until at least 2029 to meet); everything else measured is within its reference or not detected.
The bar is drawn in blocks of the 4.0 ng/L federal MCL (2024), so the length shows how far above it the result sits.

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.
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.
The records describe the system. A certified lab test shows what reaches your glass.
PFOS 6.2 ng/L, above the 4 ng/L limit

JACKSON WATER WORKS & SEWER BOARD (PWS ID AL0000256) is a public water system serving 11,715 people in Jackson, Alabama.
JACKSON WATER WORKS & SEWER BOARD is on record as drawing from surface water. The source shapes which contaminants matter most for this system.
PurityMap's record for JACKSON WATER WORKS & SEWER BOARD holds 31 findings: 1 above a reference and 30 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.
PurityMap does not issue a safety verdict. It publishes JACKSON WATER WORKS & SEWER BOARD'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.
The latest published record for JACKSON WATER WORKS & SEWER BOARD is dated 2026-09-16. Utilities report on regulatory cycles, so results reflect the monitoring period rather than a live reading.
No. It is assessed at the water-system level from JACKSON WATER WORKS & SEWER BOARD'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.
Perfluorooctanesulfonic acid (PFOS) was detected in this record. Each finding shows its measured value, its reference and its source on this page.
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.
