Read this first
- Lithium (above EPA’s health benchmark) was found in 14 of 14 samples, highest 33 ppb. Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.
No health-based violations on file since 2016. EPA lists 5 monitoring or reporting violations, which are paperwork and testing lapses rather than water quality findings.
What was found
Highlighted: above the health goal, or EPA’s health benchmark where there is no goal. Circled: above the legal limit in at least one sample, or the action level. Every scale puts that line at its middle.

What this report cannot tell you
- Levels of everything else. Federal bulk data carries results for PFAS, lithium, lead and copper, and violations for the rest. Nitrate, arsenic, disinfection byproducts and other levels are in Gardnerville Ranchos GID’s own annual report, which it must send you every year.
- 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.
- Anything after the latest data. SDWIS data is from 2026 Q2; UCMR 5 samples are from Feb. 25, 2025 to Aug. 25, 2025.

Gardnerville Ranchos GID must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.
How to read itTest your own tap for lead
Your service line, solder and fixtures decide the lead at your faucet, not the utility’s average.
Lead in your water: what to doDecide if you want a filter at all
A filter for taste or chlorine is a preference, not a need. The standards say what each kind can do.
