The short answer

1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Arsenic, above the legal limit. 5 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2017 to 2026.

Arsenic, fluoride, chromium (total), haloacetic acids (HAA5), nitrate and total trihalomethanes (TTHM): California’s own results, samples taken from Oct. 30, 2020 to June 12, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Arsenic

Comes from the source

Above the legal limit

10ppb

Highest yearly average, 2020 to 2026

2026 average: 8.8 ppb

Averaged by year, the highest was 10 ppb, in 2022: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 11 ppb. In 2026, the latest year on file, its two samples averaged 8.8 ppb. EPA judges this limit at each sampling point, and recorded violations for arsenic at this utility in 2022 and 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 12.8 ppb, in 2012, and EPA recorded violations in 2012, 2013, 2014 and 2017.

What handles it

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

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

1.6ppb

90th percentile, 2024 to 2026

In the latest period, 9 in 10 homes sampled were at or below 1.6 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

Below EPA’s limits2

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.45ppm

Highest yearly average, 2020 to 2023

2023, one sample: 0.38 ppm

Averaged by year, the highest was 0.45 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.48 ppm. In 2023, the latest year on file, its one sample was 0.38 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.47 ppm, in 2012.

What handles it

Chromium (total)

Comes from the source

Below EPA’s limits

1.1ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 1.1 ppb, in 2023, below EPA’s legal limit of 100 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 7.6 ppb, in 2012.

What handles it

3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Haloacetic acids (HAA5)
  • Nitrate
  • Total trihalomethanes (TTHM)

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

    For: Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Arsenic, Lead

    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

Moderately hard, 120 mg/L (7 grains per gallon), at its one sampling point, 2020 to 2023.

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, fluoride, chromium (total), haloacetic acids (HAA5), nitrate and total trihalomethanes (TTHM) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Leisure Acres Mutual Water Company’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 Oct. 30, 2020 to June 12, 2026.

Testing your own tap

Leisure Acres Mutual Water Company’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.
