Read this first
Nothing in the federal data for this utility is above a health goal. That covers PFAS, lithium, lead and copper; it does not cover everything, so read what this report cannot tell you below.
No health-based violations on file since 2016. EPA lists 1 monitoring or reporting violation, which are paperwork and testing lapses rather than water quality findings.
What was found
Highlighted: above the health goal, or EPA’s health benchmark where there is no goal. Circled: above the legal limit in at least one sample, or the action level. Every scale puts that line at its middle.
PFAS and lithium: EPA UCMR 5, samples taken from Feb. 27, 2023 to Aug. 8, 2023. Each blue tick on a scale is one sample where it was found.
NSF’s PFAS claims are tested to below 20 ppt. EPA’s limit is 10 ppt, and EPA says no certification yet shows a filter reaching its levels.
PFHxS
Comes from the source
6.8ppt
Highest of 12 samples; found in two
Detected, below the legal limit and the health goal.
What handles it
- NSF/ANSI 53Look for: Total PFAS Reduction
PFBS
Comes from the source
17.4ppt
Highest of 12 samples; found in two
Below EPA’s hazard index benchmark of 2,000 ppt. PFBS has no legal limit or health goal of its own.

Also found, with no federal limit
EPA measured these PFAS to learn how often they occur. None has a legal limit or a health goal yet.
| Compound | Highest sample | Found in | Certification claim |
|---|---|---|---|
| PFPeA | 11.5 ppt | 2 of 12 | None covers it |
| PFHxA | 11.3 ppt | 2 of 12 | None covers it |
| PFPeS | 8.4 ppt | 1 of 12 | None covers it |
| PFBA | 5.6 ppt | 1 of 12 | None covers it |
Tested and not found
Below EPA’s minimum reporting level in every sample taken from Feb. 27, 2023 to Aug. 8, 2023. Not found means not measured above that level, which is not the same as zero.

Violations since 2016
No health-based violations on file with EPA since 2016. There is 1 monitoring or reporting violation: a sample missed, late or not reported.
What this report cannot tell you
- Levels of everything else. Federal bulk data carries results for PFAS, lithium, lead and copper, and violations for the rest. Nitrate, arsenic, disinfection byproducts and other levels are in Purdue Univ. Water Works’s own annual report, which it must send you every year.
- Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.
- Anything after the latest data. SDWIS data is from 2026 Q2; UCMR 5 samples are from Feb. 27, 2023 to Aug. 8, 2023.

What to do next
Nothing here is above a health goal

Purdue Univ. Water Works must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.
How to read itTest your own tap for lead
Your service line, solder and fixtures decide the lead at your faucet, not the utility’s average.

A filter for taste or chlorine is a preference, not a need. The standards say what each kind can do.
