The short answer

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

What handles it

What was found

Arsenic, uranium, fluoride, total trihalomethanes (TTHM), chromium (total), haloacetic acids (HAA5) and nitrate: California’s own results, samples taken from July 21, 2020 to May 26, 2026.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

4.7ppb

Highest yearly average, 2023 to 2026

2026, one sample: 2.4 ppb

Averaged by year, the highest was 4.7 ppb, in 2024: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2026, the latest year on file, its one sample was 2.4 ppb.

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

1.2ppb

Highest yearly average, 2023 to 2026

2026: not found

Averaged by year, the highest was 1.2 ppb, in 2023: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 1.3 ppb. In 2026, the latest year on file, it wasn’t found in any of its two samples.

What handles it

Below EPA’s limits2

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.12ppm

Highest yearly average, 2023 to 2026

2026, one sample: 0.12 ppm

Averaged by year, the highest was 0.12 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. In 2026, the latest year on file, its one sample was 0.12 ppm.

What handles it

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

1.7ppb

Highest yearly average, 2023 to 2025

Averaged by year, the highest was 1.7 ppb, in 2025, below EPA’s legal limit of 80 ppb. That was also the latest year on file.

What handles it

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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

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

    For: Arsenic, Uranium

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

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.

Hardness

Soft, typically 53 mg/L (3.1 grains per gallon), across 2 sampling points, 2023 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. Arsenic, uranium, fluoride, total trihalomethanes (TTHM), 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. Riverland Resort’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 July 21, 2020 to May 26, 2026.

Testing your own tap

Riverland Resort’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.
