The short answer

1 result is above the limit’s level with no violation recorded, and 1 more is above the health goal. The worst: Haloacetic acids (HAA5), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Haloacetic acids (HAA5), arsenic, total trihalomethanes (TTHM), nitrate, fluoride and chromium (total): California’s own results, samples taken from March 12, 2020 to June 10, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the limit’s level, no violation recorded1

Above the limit’s level, no violation

87.8ppb

Highest yearly average, 2020 to 2025

2025 average: 27.2 ppb

Averaged by year, the highest was 87.8 ppb, in 2023, above EPA’s legal limit of 60 ppb. Its highest single sample was 140 ppb. In 2025, the latest year on file, its five samples averaged 27.2 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for haloacetic acids (HAA5) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 50.3 ppb, in 2016.

Above the health goal

2.2ppb

Highest yearly average, 2020 to 2025

2025: not found

Averaged by year, the highest was 2.2 ppb, in 2022: 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. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.4 ppb, in 2018.

2025 average: 57.7 ppb

Averaged by year, the highest was 61.3 ppb, in 2023, below EPA’s legal limit of 80 ppb. Its highest single sample was 79 ppb. In 2025, the latest year on file, its six samples averaged 57.7 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 47.5 ppb, in 2016.

Below EPA’s limits

0.43ppm

Highest sample; found in 4 of 66

2026: not found

The highest sample, in 2022, was 0.43 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, it wasn’t found in its one sample.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”

Below EPA’s limits

0.009ppm

Highest yearly average, 2020 to 2026

2026: not found

Averaged by year, the highest was 0.009 ppm, in 2021, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.11 ppm. In 2026, the latest year on file, it wasn’t found in its one sample.

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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    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

Soft, 12 mg/L (0.7 grains per gallon), at its one sampling point, 2019 to 2026.

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. There are 3 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5), arsenic, total trihalomethanes (TTHM), nitrate, fluoride and chromium (total) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Fcwwd 18/friant’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 March 12, 2020 to June 10, 2026.

Testing your own tap

Fcwwd 18/friant’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.
