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 South Bend tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For South Bend, PFHxS 25.6 ng/L (limit 10 ng/L) and PFOA 10 ng/L (limit 4 ng/L) were measured above their limits in EPA's 2024 testing; the lead 90th-percentile result was 4.7 µg/L against the 15 µg/L action level. SOUTH BEND WATER WORKS (PWSID IN5271014) has a Purity Score of 52/100 (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 South Bend?

SOUTH BEND WATER WORKS (PWS ID IN5271014) is the public water system on record for South Bend, Indiana, serving about 115,000 people. Confirm the utility on your water bill before acting on a specific finding.

Where does South Bend get its drinking water?

Groundwater (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in South Bend's water?

Yes. In EPA's UCMR 5 testing (2023-10-24 to 2024-05-14), PFHxS was measured at 25.6 ng/L against a 10 ng/L federal limit and PFOA was measured at 10 ng/L against a 4 ng/L federal limit. PFBS (8.7 ng/L, below the 2,000 ng/L EPA health advisory) and PFHxA (20.8 ng/L, below the 400,000 ng/L state limit) were also detected. PFBA (23.2 ng/L), PFHpA (8.3 ng/L), PFPeA (39.7 ng/L) and PFPeS (7.2 ng/L) were also detected; they have no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.

Is there lead in South Bend's tap water?

SOUTH BEND WATER WORKS's most recent lead 90th-percentile result (2023–2025) was 4.7 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

What does the latest South Bend water report show?

PurityMap's current record for South Bend holds 31 findings: 2 above a reference, 3 detected within the reference, 4 detected with no limit and 22 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
