Canutillo, TX tap water
Supplied mostly by El Paso Water, 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 EPA monitoring data (2012–2019).
Nitrate (NO₃)
0.2–15 ppm (Low)
Typical 3.3 ppm
Low, so water changes lower your tank's nitrate well.
From El Paso Water's 2025 water quality report; El Paso Water Utilities, which supplies Gaslight Square Mobile Home Park.
Copper at home taps (first draw)
0.02–0.69 ppm (Worth knowing)
The 90th percentile of first-draw samples from homes: water that sat in household pipes for at least six hours.
Shrimp and snails are sensitive to copper. Water that sits in household pipes picks up the most; it drops once the tap has run for a minute.

Chlorine or chloramine at the tap
0–2.6 ppm
Typical 2 ppm
