The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Uranium, above the legal limit. 26 health-based violations since 2016.

What handles it

What was found

Uranium, arsenic, nitrate, fluoride and chromium (total): California’s own results, samples taken from April 7, 2020 to June 30, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Uranium

Comes from the source

Above the legal limit

363ppb

Highest yearly average, 2020 to 2026

2026 average: 220 ppb

Averaged by year, the highest was 363 ppb, in 2020, about 12 times EPA’s legal limit of 30 ppb. Its highest single sample was 507 ppb. In 2026, the latest year on file, its four samples averaged 220 ppb, above the limit. EPA recorded violations for uranium at this utility in 2020, 2021, 2022, 2023, 2024 and 2025. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 193 ppb, in 2019, and EPA recorded violations in 2012, 2013, 2015, 2016, 2017, 2018 and 2019.

What handles it

Above the health goal1

Arsenic

Comes from the source

Above the health goal

9.5ppb

Highest yearly average, 2020 to 2025

Averaged by year, the highest was 9.5 ppb, in 2025: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 11 ppb. That was also the latest year on file. EPA recorded no violation for arsenic at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.4 ppb, in 2018.

Nitrate

Comes from the source

Below EPA’s limits

7.3ppm

Highest sample; found in 7 of 7

2025, one sample: 0.79 ppm

The highest sample, in 2023, was 7.3 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, its one sample was 0.79 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.1 ppm, in 2018.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.47ppm

Highest yearly average, 2022 to 2025

2025, one sample: 0.39 ppm

Averaged by year, the highest was 0.47 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. In 2025, the latest year on file, its one sample was 0.39 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.26 ppm, in 2019.

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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

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

    For: Uranium, 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

Moderately hard, 120 mg/L (7 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. Uranium, arsenic, nitrate, fluoride and chromium (total) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Two Twenty Four Mobile Home Pk’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 April 7, 2020 to June 30, 2026.

Testing your own tap

Two Twenty Four Mobile Home Pk’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.
