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

  1. 01 · TestTest your own tap

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

Questions

Frequently asked questions

Who does Brainerd serve?

Brainerd (PWS ID MN1180002) is a public water system serving 14,670 people in Brainerd, Minnesota.

Where does Brainerd get its water?

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

What does Brainerd's monitoring record show?

PurityMap's record for Brainerd holds 32 findings: 1 above a reference, 1 detected within the reference and 30 not detected, from 32 evidence records. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.

Is Brainerd's water safe to drink?

PurityMap does not issue a safety verdict. It publishes Brainerd'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 Brainerd data?

The latest published record for Brainerd is dated 2026-10-15. 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 Brainerd'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 Brainerd?

Copper (90th percentile) 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 lead in Brainerd'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.
