Track record

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.

Questions

Frequently asked questions

Is Reedsburg tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Reedsburg, PFAS were detected below the federal limits. REEDSBURG WATERWORKS (PWSID WI1570102) has a Purity Score of 92/100 (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 Reedsburg?

REEDSBURG WATERWORKS (PWS ID WI1570102) is the public water system on record for Reedsburg, Wisconsin, serving about 9,984 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Reedsburg get its drinking water?

Groundwater (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Reedsburg's water?

In EPA's UCMR 5 testing (2023-06-20 to 2023-12-19), PFHxS was detected at 4.4 ng/L, below the 10 ng/L federal limit.

Is there lead in Reedsburg's tap water?

Lead is not in Reedsburg'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 Reedsburg water report show?
