The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, chromium (total) and nitrate: California’s own results, samples taken from Feb. 3, 2020 to May 5, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

2.4ppb

Highest yearly average, 2020 to 2025

2025: not found

Averaged by year, the highest was 2.4 ppb, in 2023: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2025, the latest year on file, it wasn’t found in its one sample.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Uranium

Comes from the source

Above the health goal

3.0ppb

Highest yearly average, 2022

Averaged by year, the highest was 3.0 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.

What handles it

Below EPA’s limits3

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

38.8ppb

Highest yearly average, 2020 to 2026

2026 average: 23.3 ppb

Averaged by year, the highest was 38.8 ppb, in 2023, below EPA’s legal limit of 60 ppb. Its highest single sample was 46 ppb. In 2026, the latest year on file, its four samples averaged 23.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 36.6 ppb, in 2017.

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

46.3ppb

Highest yearly average, 2020 to 2026

2026 average: 36.3 ppb

Averaged by year, the highest was 46.3 ppb, in 2023, below EPA’s legal limit of 80 ppb. Its highest single sample was 73 ppb. In 2026, the latest year on file, its four samples averaged 36.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 49.8 ppb, in 2014.

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.2ppm

Highest yearly average, 2020 to 2025

2025, one sample: 0.15 ppm

Averaged by year, the highest was 0.2 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. In 2025, the latest year on file, its one sample was 0.15 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.2 ppm, in 2015.

  • Lead
  • Nitrate

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Uranium

    For: Arsenic, Uranium

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

Hardness

Hard, 130 mg/L (7.6 grains per gallon), at its one sampling point, 2019 to 2025.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

What this report can’t tell you

  • Everything else. Arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, chromium (total) and nitrate results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Springville PUD’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 didn’t sample this utility; California’s results run from Feb. 3, 2020 to May 5, 2026.

Testing your own tap

Springville PUD’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab California certifies.
