The short answer
1 result is above EPA’s legal limit. The worst: Haloacetic acids (HAA5), above the legal limit. 5 health-based violations since 2016.
What was found
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.4 ppm, for the period ending June 30, 2011. None since is on file, so it is not counted as a current finding.
Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, chromium (total), nitrate and arsenic: California’s own results, samples taken from March 30, 2020 to June 5, 2026, with EPA’s 2012 to 2019 file for earlier years.

81.5ppb
Highest yearly average, 2020 to 2026
2026: not found
Averaged by year, the highest was 81.5 ppb, in 2023, above EPA’s legal limit of 60 ppb. Its highest single sample was 210 ppb.

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
- Arsenic
- Lead
Hardness
Moderately hard, typically 86 mg/L (5 grains per gallon), across 2 sampling points, 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. Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, chromium (total), nitrate and arsenic results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Bridgehaven 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 March 30, 2020 to June 5, 2026.
