The short answer
1 result is above EPA’s legal limit. The worst: Arsenic, above the legal limit. 33 health-based violations since 2016.
What handles itWhat was found
Arsenic, fluoride, total trihalomethanes (TTHM), chromium (total), haloacetic acids (HAA5) and nitrate: California’s own results, samples taken from Feb. 19, 2020 to May 20, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit1
Arsenic
Comes from the source
51.3ppb
Highest yearly average, 2020 to 2026
2026 average: 43.5 ppb
Averaged by year, the highest was 51.3 ppb, in 2024, about 5.1 times EPA’s legal limit of 10 ppb. Its highest single sample was 57 ppb. In 2026, the latest year on file, its two samples averaged 43.5 ppb, above the limit. EPA recorded violations for arsenic 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 47.3 ppb, in 2012, and EPA recorded violations in 2014, 2015, 2016, 2017 and 2018.

Fluoride
Forms or is added in treatment
1.1ppm
Highest yearly average, 2021 to 2026
2026, one sample: 1.1 ppm
Averaged by year, the highest was 1.1 ppm, in 2021, below EPA’s legal limit of 4.0 ppm. In 2026, the latest year on file, its one sample was 1.1 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.2 ppm, in 2015.

Total trihalomethanes (TTHM)
Forms or is added in treatment
2.5ppb
Highest yearly average, 2020 to 2026
2026: not found
Averaged by year, the highest was 2.5 ppb, in 2021, below EPA’s legal limit of 80 ppb. Its highest single sample was 5.0 ppb. In 2026, the latest year on file, it wasn’t found in its one sample.

- Chromium (total)
- Haloacetic acids (HAA5)
- 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
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, 31 mg/L (1.8 grains per gallon), at its one sampling point, 2021 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.

What this report can’t tell you
Everything else. Arsenic, fluoride, total trihalomethanes (TTHM), chromium (total), haloacetic acids (HAA5) and nitrate results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. The Village Mobile Home Park’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. 19, 2020 to May 20, 2026.
