Homestead Valley, CA tap water
Supplied mostly by Bighorn - Desert View Water Agency, plus 2 other utilities. Here's what the water means for your fish.
Disinfectant
Chlorine
Your water is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it.
Safety for fish and shrimp
Nitrite (NO₂)
Not detected (Low)
Not detected in testing, so any nitrite in your tank comes from the tank itself.
From EPA monitoring data (2017).
Nitrate (NO₃)
5.3–15 ppm (Low)
Typical 7.1 ppm
Water changes can't take your tank's nitrate below this level.
From California Water Board lab results, measured before treatment; California Water Board lab results (2023–2026).
Copper at home taps
Up to 0.08 ppm (Low)
Typically not detected
