The short answer

1 result is above the health goal. The worst: Lead, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2008 to 2024.

Nitrate, fluoride, arsenic, chromium (total) and total trihalomethanes (TTHM): California’s own results, samples taken from Sept. 20, 2021 to April 16, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

12ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 12 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

What handles it

Below EPA’s limits2

Nitrate

Comes from the source

Below EPA’s limits

9.2ppm

Highest sample; found in 24 of 24

2026, one sample: 1.8 ppm

The highest sample, in 2023, was 9.2 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 1.8 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 4.5 ppm, in 2018.

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

Below EPA’s limits

0.019ppm

Highest yearly average, 2022 to 2024

2024: not found

Averaged by year, the highest was 0.019 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.056 ppm. In 2024, the latest year on file, it wasn’t found in any of its three samples.

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.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

Hardness

Moderately hard, typically 95 mg/L (5.5 grains per gallon), across 3 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.

Violations since 2016

No health-based violations on file with EPA since 2016. There is 1 monitoring or reporting violation: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Nitrate, fluoride, arsenic, chromium (total) and total trihalomethanes (TTHM) results here are California’s own from 2021 on, with EPA’s national file for 2012 to 2019. Candlelight Village Mutual Water Co.’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 Sept. 20, 2021 to April 16, 2026.

Testing your own tap

Candlelight Village Mutual Water Co.’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.
