The short answer

3 results are above the limit’s level with no violation recorded, and 2 more are above the health goal. The worst: Haloacetic acids (HAA5), above the limit’s level, no violation. 4 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2003 to 2024.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), uranium, arsenic, fluoride, nitrate and chromium (total): California’s own results, samples taken from Jan. 20, 2020 to June 16, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the limit’s level, no violation recorded3

Haloacetic acids (HAA5)

Above the limit’s level, no violation

97ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 97 ppb, in 2026, above EPA’s legal limit of 60 ppb. Its highest single sample was 170 ppb. That was also the latest year on file. EPA judges this limit on running averages at each sampling point, and recorded no violation for haloacetic acids (HAA5) 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 75 ppb, in 2016, and EPA recorded a violation in 2016.

109ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 109 ppb, in 2026, above EPA’s legal limit of 80 ppb. Its highest single sample was 200 ppb. That was also the latest year on file. EPA judges this limit on running averages at each sampling point, and recorded no violation for total trihalomethanes (TTHM) 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 53.8 ppb, in 2015.

Averaged by year, the highest was 32 ppb, in 2026, above EPA’s legal limit of 30 ppb. Its highest single sample was 38.7 ppb. That was also the latest year on file. 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 33.1 ppb, in 2016.

2025 average: 1.3 ppb

Averaged by year, the highest was 1.4 ppb, in 2020: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 3.3 ppb. In 2025, the latest year on file, its two samples averaged 1.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.4 ppb, in 2012.

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

    For: Total trihalomethanes (TTHM), Lead, Arsenic

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

  • NSF/ANSI 58

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

    For: Total trihalomethanes (TTHM), Uranium, Lead, Arsenic

    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 to moderately hard depending on the source, 18 to 72 mg/L (1.1 to 4.2 grains per gallon), across 2 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. Haloacetic acids (HAA5), total trihalomethanes (TTHM), uranium, arsenic, fluoride, nitrate and chromium (total) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. June Lake PUD Village’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. 20, 2020 to June 16, 2026.

Testing your own tap

June Lake PUD Village’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.
