The short answer

3 results are above the health goal. The worst: Lead, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2025.

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.7 ppm, for the period ending Dec. 31, 1995. None since is on file, so it is not counted as a current finding.

Arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride and chromium (total): California’s own results, samples taken from Aug. 5, 2020 to June 17, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal3

Lead

Comes from pipes, often your own

Above the health goal

12.1ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 12.1 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

Arsenic

Comes from the source

Above the health goal

7.0ppb

Highest yearly average, 2020 to 2025

Averaged by year, the highest was 7.0 ppb, in 2025: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 21 ppb. That was also the latest year on file. EPA recorded no violation for arsenic at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.8 ppb, in 2017.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Uranium

Comes from the source

Above the health goal

3.9ppb

Highest yearly average, 2024

Averaged by year, the highest was 3.9 ppb, in 2024: 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 limits4

Haloacetic acids (HAA5)

Below EPA’s limits

46ppb

Highest yearly average, 2020 to 2026

2026: not found

Averaged by year, the highest was 46 ppb, in 2021, below EPA’s legal limit of 60 ppb. Its highest single sample was 62 ppb. In 2026, the latest year on file, it wasn’t found in its one sample. EPA recorded no violation for haloacetic acids (HAA5) at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 54.6 ppb, in 2015.

Total trihalomethanes (TTHM)

Below EPA’s limits

40.2ppb

Highest yearly average, 2020 to 2026

2026, one sample: 1.2 ppb

Averaged by year, the highest was 40.2 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2026, the latest year on file, its one sample was 1.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 34.8 ppb, in 2018.

Nitrate

Comes from the source

Below EPA’s limits

2.6ppm

Highest sample; found in 3 of 30

2025 average: 0.52 ppm

The highest sample, in 2025, was 2.6 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its five samples averaged 0.52 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.5 ppm, in 2014.

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

0.27ppm

Highest yearly average, 2020 to 2025

2025 average: 0.083 ppm

Averaged by year, the highest was 0.27 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 1.1 ppm. In 2025, the latest year on file, its three samples averaged 0.083 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.32 ppm, in 2016.

What handles it

  • Chromium (total)

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.”

  • NSF/ANSI 53

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Uranium

    For: Lead, Arsenic, Uranium

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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

Soft, typically 34 mg/L (2 grains per gallon), across 5 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. Arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride and chromium (total) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Pinecrest Permittees Assn’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 Aug. 5, 2020 to June 17, 2026.

Testing your own tap

Pinecrest Permittees Assn’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.
