The ZIP code it serves
The short answer
1 result is above EPA’s legal limit, 1 more is above the limit’s level with no violation recorded, and 2 more are above the health goal. The worst: Nitrate, above the legal limit. 7 health-based violations since 2016.
What handles itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 2013 to 2026.
Nitrate, arsenic, uranium, fluoride and chromium (total): California’s own results, samples taken from March 11, 2020 to June 2, 2026, with EPA’s 2012 to 2019 file for earlier years.
Total trihalomethanes (TTHM): EPA’s compliance monitoring file, samples taken from March 19, 2014 to March 19, 2014. Newer results are in the utility’s annual water quality report.
Above the legal limit1
Nitrate
Comes from the source
14ppm
Highest sample; found in 59 of 60
2026 average: 12.3 ppm
From 2021 to 2026, at least 25 samples were above EPA’s legal limit of 10 ppm, the highest 14 ppm in 2025. The next sample at the same point, within 30 days, kept the average above the limit for 13; one came back under and 11 have no follow-up sample on file within 30 days. In 2026, the latest year on file, its six samples averaged 12.3 ppm, above the limit. EPA recorded violations for nitrate at this utility in 2021, 2023 and 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 9.3 ppm, in 2017.

- NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
Above the limit’s level, no violation recorded1
Arsenic
Comes from the source
72ppb
Highest yearly average, 2020 to 2026
2026, one sample: 4.0 ppb
Averaged by year, the highest was 72 ppb, in 2024, about 7.2 times EPA’s legal limit of 10 ppb. In 2026, the latest year on file, its one sample was 4.0 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for arsenic 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 45 ppb, in 2012.

Above the health goal2
Lead
Comes from pipes, often your own
3.0ppb
90th percentile, 2024 to 2026
In the latest period, 9 in 10 homes sampled were at or below 3.0 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.

Uranium
Comes from the source
1.8ppb
Highest yearly average, 2024
Averaged by year, the highest was 1.8 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. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.7 ppb, in 2012.
What handles it
- NSF/ANSI 58 look for “Uranium”
Below EPA’s limits1
Fluoride
Forms or is added in treatment
0.41ppm
Highest yearly average, 2020 to 2026
2026: not found
Averaged by year, the highest was 0.41 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. In 2026, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.17 ppm, in 2014.

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: Nitrate/Nitrite (30 ppm challenge), Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction
For: Nitrate, Arsenic, Lead
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Nitrate/Nitrite Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction, Uranium
For: Nitrate, Arsenic, Lead, Uranium
Other certifiers’ wording: Nitrate; 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
Hard to very hard depending on the source, 156 to 240 mg/L (9.1 to 14 grains per gallon), across 2 sampling points, 2020 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. Nitrate, arsenic, uranium, fluoride and chromium (total) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Total trihalomethanes (TTHM) comes from EPA’s file alone, which ends in 2019. Spring Canyon WA’s own annual report, which it must send you every year, has newer results for those and 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 March 11, 2020 to June 2, 2026; EPA’s compliance samples are from March 19, 2014 to March 19, 2014.
