The short answer

1 result is above EPA’s legal limit. The worst: Lead, above the action level. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2008 to 2026.

Fluoride, arsenic, chromium (total) and nitrate: California’s own results, samples taken from Jan. 2, 2020 to June 17, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Lead

Comes from pipes, often your own

Above the action level

16ppb

90th percentile, 2024 to 2026

In the latest period, 9 in 10 homes sampled were at or below 16 ppb, above 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

Fluoride

Below EPA’s limits

0.13ppm

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 0.13 ppm, in 2026, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.2 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.23 ppm, in 2014.

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.

The best water filters for lead, ranked

Hardness

Soft to very hard depending on the source, 21 to 226 mg/L (1.2 to 13.2 grains per gallon), across 2 sampling points, 2019 to 2026.

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. Fluoride, arsenic, chromium (total) and nitrate results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Rite of Passage/Sierra Ridge’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 Jan. 2, 2020 to June 17, 2026.

Testing your own tap

Rite of Passage/Sierra Ridge’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.
