The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Nitrate, arsenic, chromium (total) and fluoride: California’s own results, samples taken from March 11, 2020 to March 4, 2026, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from Jan. 16, 2019 to Jan. 16, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Uranium

Comes from the source

Above the health goal

0.12ppb

Highest yearly average, 2019

Averaged by year, the highest was 0.12 ppb, in 2019: 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

Below EPA’s limits1

Nitrate

Comes from the source

Below EPA’s limits

0.27ppm

Highest sample; found in 1 of 6

2026: not found

The highest sample, in 2023, was 0.27 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.7 ppm, in 2017.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

  • Fluoride
  • 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.”

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.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

Hardness

Hard, 170 mg/L (9.9 grains per gallon), at its one sampling point, 2020 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. Nitrate, arsenic, chromium (total) and fluoride results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Uranium comes from EPA’s file alone, which ends in 2019. Fenner Canyon Youth Conservation Camp’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 March 11, 2020 to March 4, 2026; EPA’s compliance samples are from Jan. 16, 2019 to Jan. 16, 2019.

Testing your own tap

Fenner Canyon Youth Conservation Camp’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.
