The ZIP code it serves
The short answer
2 results are above the health goal. The worst: Arsenic, above the health goal. 1 health-based violation since 2016.
What handles itWhat was found
Arsenic, nitrate and chromium (total): California’s own results, samples taken from Feb. 19, 2020 to May 20, 2020, with EPA’s 2012 to 2019 file for earlier years.
Uranium and fluoride: EPA’s compliance monitoring file, samples taken from May 13, 2014 to June 21, 2017. Newer results are in the utility’s annual water quality report.
Above the health goal2
Arsenic
Comes from the source
4.0ppb
Highest yearly average, 2020
Averaged by year, the highest was 4.0 ppb, in 2020: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 38 ppb, in 2017.
What handles it
- NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
- NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
Uranium
Comes from the source
6.5ppb
Highest yearly average, 2016
Averaged by year, the highest was 6.5 ppb, in 2016: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.
What handles it
- NSF/ANSI 58 look for “Uranium”
Below EPA’s limits2
Nitrate
Comes from the source
4.8ppm
One sample
2020, one sample: 4.8 ppm
The highest sample, in 2020, was 4.8 ppm, below EPA’s legal limit of 10 ppm. That is the only year on file, and its one sample was 4.8 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 8.9 ppm, in 2019.
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
0.35ppm
Highest yearly average, 2014 to 2017
2017, one sample: 0.3 ppm
Averaged by year, the highest was 0.35 ppm, in 2014, below EPA’s legal limit of 4.0 ppm. In 2017, the latest year on file, its one sample was 0.3 ppm.
What handles it
- NSF/ANSI 58 look for “Fluoride Reduction”
- NSF/ANSI 53 look for “Fluoride”
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: Arsenic (Pentavalent)<=50 ppb Reduction, Uranium
For: Arsenic, Uranium
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.

What this report can’t tell you
Everything else. Arsenic, nitrate and chromium (total) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Uranium and fluoride come from EPA’s file alone, which ends in 2019. Alpine Springs Mobile Home Park’s own annual report, which it must send you every year, has newer results for those and 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, 2020; EPA’s compliance samples are from May 13, 2014 to June 21, 2017.
