The short answer
1 result is above the limit’s level with no violation recorded. The worst: Uranium, above the limit’s level, no violation. 1 health-based violation since 2016.
What handles itWhat was found
Uranium, fluoride, total trihalomethanes (TTHM), arsenic, chromium (total), haloacetic acids (HAA5) and nitrate: California’s own results, samples taken from Jan. 21, 2020 to Jan. 28, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the limit’s level, no violation recorded1
Uranium
Comes from the source
59.6ppb
Highest yearly average, 2020 to 2026
2026, one sample: 20.9 ppb
Averaged by year, the highest was 59.6 ppb, in 2025, about twice EPA’s legal limit of 30 ppb. In 2026, the latest year on file, its one sample was 20.9 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for uranium at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 13.3 ppb, in 2013.

2026, one sample: 0.36 ppm
Averaged by year, the highest was 0.37 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.39 ppm. In 2026, the latest year on file, its one sample was 0.36 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.38 ppm, in 2015.

2023 average: 2.0 ppb
Averaged by year, the highest was 3.2 ppb, in 2020, below EPA’s legal limit of 80 ppb. Its highest single sample was 4.4 ppb. In 2023, the latest year on file, its four samples averaged 2.0 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.2 ppb, in 2019.

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.”

Claim: Uranium
For: Uranium
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.
Compare five-year costsHardness
Soft to moderately hard depending on the source, 10 to 63 mg/L (0.6 to 3.7 grains per gallon), across 3 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. Uranium, fluoride, total trihalomethanes (TTHM), arsenic, chromium (total), haloacetic acids (HAA5) and nitrate results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Pinyon Crest HOA’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.
