The short answer
Nothing in EPA’s and California’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 1 health-based violation since 2016.
What was found
Nitrate, arsenic, chromium (total) and fluoride: California’s own results, samples taken from March 24, 2020 to May 15, 2026, with EPA’s 2012 to 2019 file for earlier years.
Total trihalomethanes (TTHM): EPA’s compliance monitoring file, samples taken from Dec. 19, 2017 to Dec. 19, 2017. Newer results are in the utility’s annual water quality report.
Below EPA’s limits1
Nitrate
Comes from the source
0.25ppm
Highest sample; found in 7 of 14
2026 average: 0.065 ppm
The highest sample, in 2022, was 0.25 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its two samples averaged 0.065 ppm.
What handles it
- NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
- NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
5 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
- Arsenic
- Chromium (total)
- Fluoride
- Lead
- Total trihalomethanes (TTHM)
Hardness
Moderately hard, typically 84 mg/L (4.9 grains per gallon), across 2 sampling points, in 2020.
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, chromium (total) and fluoride results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Total trihalomethanes (TTHM) comes from EPA’s file alone, which ends in 2019. Creekside Mobilehome 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.
