PFAS in Indiana tap water

In EPA's 2024 UCMR 5 testing, 9 cities of 72 had a regulated PFAS (PFOA, PFOS or PFHxS) above the new federal limit, and PFAS were detected at any level in 10.

Lead in Indiana tap water

Utilities report lead as the 90th-percentile result from sampled home taps. 64 of 72 Indiana cities reported a value above zero, and 0 cities were above the 15 µg/L federal action level. Lead usually enters water from a building's own pipes, so a test at your tap is the only way to know what you drink.

Lead across Indiana Filters certified for lead

Does Indiana have hard water?Hardness comes from each utility's own annual water-quality report. PurityMap only shows it where that report is on file, so many cities have no hardness value yet.

Utility reports on file give hardness for 1 city in Indiana. Hardness affects scale, appliances and soap; it is not a health finding.

Frequently asked questions

How does Indiana tap water compare across cities?

PurityMap ranks 72 cities in Indiana by their Purity Score, computed only from contaminants measured in the published EPA record. Lafayette has the highest published score (100/100). The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.

How many Indiana cities have PFAS above the federal limit?

9 cities of 72 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including Brown County (PFOA 12.9 ng/L), South Bend (PFHxS 25.6 ng/L), Pike-Gibson (PFOA 7.9 ng/L). PFAS were detected at any level in 10.

Is there lead in Indiana tap water?

Utilities report lead as a 90th-percentile result from home taps. 64 of 72 Indiana cities reported a value above zero, and none was above the 15 µg/L federal action level. Lead usually comes from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

Have Indiana water systems had drinking-water violations?

4 cities in Indiana have a health-based violation in the federal SDWIS record within about the last ten years. Each city report lists the contaminant, year and whether it was resolved.

Does Indiana have hard water?

Hardness is published in utility water-quality reports for 1 Indiana city on record; the hardest is Fort Wayne at 7.6 grains per gallon. Hardness affects scale and appliances; it is not a health finding.

Limits, sources and corrections

A statewide page cannot tell you what reaches a specific address. Water quality varies by supplier, sampling period and household plumbing; open a city report for the evidence behind a local result.

Sources: EPA UCMR 5 (PFAS, 2024), SDWIS Lead and Copper Rule 90th-percentile results and health-based violations, and utility Consumer Confidence Reports where on file. Every city report links its dated source records.
