Escalon, CA tap water
Supplied mostly by City of Escalon, plus 1 other utility. 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 California Water Board lab results (2025–2026).
Nitrate (NO₃)
Up to 30 ppm (High)
Typical 30 ppm
High for tap water. Water changes can't take your tank's nitrate below this level.
From EPA monitoring data; California Water Board lab results (2012–2026).
Copper at home taps
Not detected (Low)
Not detected in testing. Water that sits in household pipes overnight can still pick some up.
