The short answer
1 result is above EPA’s health benchmark. The worst: Lithium, above EPA’s health benchmark. No health-based violations on file since 2016.
What was found
PFAS and lithium: EPA UCMR 5, samples taken from Feb. 21, 2024 to Aug. 20, 2024.
Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, chromium (total), arsenic and uranium: Texas’s own results, samples taken from Aug. 5, 2020 to June 1, 2026, with EPA’s 2012 to 2019 file for earlier years.
PFAS: None of the six PFAS in EPA’s 2024 drinking water rule was found in this utility’s samples. None of the other 23 PFAS tested for was found either.

| Results from EPA’s UCMR 5 sampling. “Below” is the lab’s reporting level: a result under it reads as not found, which is not the same as zero. The limits are EPA’s 2024 rule, with compliance due from 2029; EPA has since proposed changes to some of them, explained on each compound’s page. PFBS has no limit of its own and counts only toward the Hazard Index, which adds up the four, each against EPA’s health-based level, from each sampling location’s average, as EPA’s UCMR 5 summary does. It counts only where two or more of the four were found, and is above the limit from 1.5. | ||
Above EPA’s health benchmark1
Lithium
Comes from the source
16.5ppb
Highest sample, Feb. 21, 2024; found in 12 of 26
The highest sample was 16.5 ppb, above EPA’s health reference level of 10 ppb. That is a screening level, not an enforceable limit.

Total trihalomethanes (TTHM)
Forms or is added in treatment
47.5ppb
Highest yearly average, 2020 to 2026

Nitrate
Comes from the source
0.63ppm
Highest sample; found in 83 of 83
2026 average: 0.054 ppm
The highest sample, in 2021, was 0.63 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its five samples averaged 0.054 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.66 ppm, in 2013.

Disinfectant
Pritchett WSC reported disinfecting with chlorine, not chloramine, at all 13 of its sampling points, in its 2024 sampling for EPA.
Chlorine leaves water that sits out for a few days, CDC says. A filter certified for it carries a chlorine claim under NSF/ANSI 42; a shower filter, a free chlorine claim under NSF/ANSI 177. This is what the utility reported for that sampling. Its annual water quality report says what it uses now.
Violations since 2016
No health-based violations on file with EPA since 2016. There are 8 monitoring or reporting violations: a sample missed, late or not reported.
What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, chromium (total), arsenic and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Pritchett WSC’s own annual report, which it must send you every year, has the contaminants this page does not show.
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.
What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.
Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 samples are from Feb. 21, 2024 to Aug. 20, 2024; Texas’s results run from Aug. 5, 2020 to June 1, 2026.
