The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Nitrate, above the legal limit. 24 health-based violations since 2016.

What handles it

What was found

Nitrate, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride and chromium (total): California’s own results, samples taken from Jan. 29, 2020 to May 27, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Nitrate

Comes from the source

Above the legal limit

66.4ppm

Highest sample; found in 217 of 227

2026 average: 21.6 ppm

From 2020 to 2026, at least 25 samples were above EPA’s legal limit of 10 ppm, the highest 66.4 ppm in 2026. The next sample at the same point, within 30 days, kept the average above the limit for eight; 17 have no follow-up sample on file within 30 days. That was also the latest year on file, and its four samples averaged 21.6 ppm, above the limit. EPA recorded violations for nitrate at this utility in 2020 and 2021. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 47 ppm, in 2018, and EPA recorded violations in 2016, 2017, 2018 and 2019.

Above the health goal

1.2ppb

Highest yearly average, 2024

Averaged by year, the highest was 1.2 ppb, in 2024: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 2.4 ppb. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.9 ppb, in 2014.

2023, one sample: 2.1 ppb

Averaged by year, the highest was 12 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, its one sample was 2.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.2 ppb, in 2019.

2023: not found

Averaged by year, the highest was 3.2 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2023, 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 3.0 ppb, in 2019.

Fluoride

Below EPA’s limits

0.14ppm

Highest yearly average, 2024

Averaged by year, the highest was 0.14 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.14 ppm. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.065 ppm, in 2018.

What handles it

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Chromium (total)
  • Lead

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

    Claims: Nitrate/Nitrite (30 ppm challenge), Arsenic (Pentavalent)<=50 ppb Reduction

    For: Nitrate, Arsenic

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

  • NSF/ANSI 58

    Claims: Nitrate/Nitrite Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Nitrate, Arsenic

    Other certifiers’ wording: Nitrate; 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

Very hard, typically 709 mg/L (41.5 grains per gallon), across 2 sampling points, in 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.

What this report can’t tell you

  • Everything else. Nitrate, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride and chromium (total) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Gleanings for the Hungry’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. 29, 2020 to May 27, 2026.

Testing your own tap

Gleanings for the Hungry’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.
