Lucerne Valley, CA tap water
About 35% of Lucerne Valley is inside a utility's service area. Homes outside it likely use private wells, which no utility tests.
Disinfectant
Chlorine
Utility water here is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it. Private wells aren't treated by a utility, so there's no chlorine or chloramine unless a treatment system adds it.
Safety for fish and shrimp
Nitrate (NO₃)
2.8–9.7 ppm (Low)
Typical 3.1 ppm
Low, so water changes lower your tank's nitrate well.
From California Water Board lab results, measured before treatment (2023–2026).
Copper at home taps
Up to 0.04 ppm (Low)
Typical 0.04 ppm
Low. Water that sits in household pipes overnight can carry more than this.
From California Water Board lab results (2023–2025).
Water chemistry
General hardness
150–230 ppm
Typical 213 ppm
Moderately hard. Great for livebearers, and most community fish adapt.
From California Water Board lab results, measured before treatment (2023–2026).
Carbonate hardness (alkalinity)
93–210 ppm
Typical 190 ppm
Strong buffering. pH stays steady and hard to lower without RO water.
From California Water Board lab results, measured before treatment (2023–2026).
pH
7.6–7.8
Typical 7.8
Most community fish do well here. Stable water matters more than the exact number.
From California Water Board lab results, measured before treatment (2023–2026).
Total dissolved solids
255–430 ppm
Typical 320 ppm
A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
From California Water Board lab results, measured before treatment (2023–2026).
