The short answer

1 result is above the limit’s level with no violation recorded. The worst: Total trihalomethanes (TTHM), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Total trihalomethanes (TTHM), nitrate, arsenic, chromium (total), fluoride and uranium: California’s own results, samples taken from April 1, 2020 to April 23, 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

169ppb

Highest yearly average, 2024 to 2025

2025, one sample: 62 ppb

Averaged by year, the highest was 169 ppb, in 2024, about twice EPA’s legal limit of 80 ppb. Its highest single sample was 325 ppb. In 2025, the latest year on file, its one sample was 62 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for total trihalomethanes (TTHM) 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.

2026 average: 0.85 ppm

The highest sample, in 2020, was 3.4 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its two samples averaged 0.85 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 3.1 ppm, in 2013.

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: Trihalomethanes (TTHM) Reduction

    For: Total trihalomethanes (TTHM)

    Other certifiers’ wording: VOC Reduction

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 216 mg/L (12.6 grains per gallon), across 2 sampling points, 2022 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.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), nitrate, arsenic, chromium (total), fluoride and uranium results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Country Leisure Mobile Estates’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 1, 2020 to April 23, 2026.

Testing your own tap

Country Leisure Mobile Estates’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.
