From the utility's inventory reported to EPA (2026Q2). Look up your address with the utility.
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.
A tap test can confirm levels at your home before you choose treatment.
PFPeA 3.5 ng/L detected (no federal or state limit)

BROWNSBURG WATER WORKS (PWS ID IN5232002) is a public water system serving 31,250 people in Brownsburg, Indiana.
BROWNSBURG WATER WORKS is on record as drawing from surface water. The source shapes which contaminants matter most for this system.
PurityMap's record for BROWNSBURG WATER WORKS holds 31 findings: 1 detected within the reference, 1 detected with no limit 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.
PurityMap does not issue a safety verdict. It publishes BROWNSBURG WATER WORKS'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 BROWNSBURG WATER WORKS is dated 2026-10-15. 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 BROWNSBURG WATER WORKS'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.
Lithium and Perfluoropentanoic acid (PFPeA) were 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.
