The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Uranium, nitrate, fluoride, chromium (total), arsenic, haloacetic acids (HAA5) and total trihalomethanes (TTHM): California’s own results, samples taken from Jan. 8, 2020 to April 8, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Uranium

Comes from the source

Above the health goal

5.6ppb

Highest yearly average, 2021 to 2026

2026 average: 5.1 ppb

Averaged by year, the highest was 5.6 ppb, in 2024: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 10.9 ppb. In 2026, the latest year on file, its four samples averaged 5.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 7.3 ppb, in 2014.

What handles it

Below EPA’s limits3

Nitrate

Comes from the source

Below EPA’s limits

8.8ppm

Highest sample; found in 76 of 76

2026 average: 6.6 ppm

The highest sample, in 2022, was 8.8 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its eight samples averaged 6.6 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 10.0 ppm, in 2012.

Fluoride

Below EPA’s limits

0.57ppm

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 0.57 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.7 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.1 ppm, in 2018.

What handles it

Chromium (total)

Comes from the source

Below EPA’s limits

14ppb

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 14 ppb, in 2024, below EPA’s legal limit of 100 ppb. That was also the latest year on file.

  • Arsenic
  • Haloacetic acids (HAA5)
  • Lead
  • Total trihalomethanes (TTHM)

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.”

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.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

Hardness

Very hard, typically 342 mg/L (20 grains per gallon), across 4 sampling points, 2021 to 2024.

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.

Violations since 2016

No health-based violations on file with EPA since 2016.

What this report can’t tell you

  • Everything else. Uranium, nitrate, fluoride, chromium (total), arsenic, haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Spv Water Company’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 Jan. 8, 2020 to April 8, 2026.

Testing your own tap

Spv Water Company’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.
