Haskell, OK tap water
Supplied mostly by Haskell Pwa-Wells, plus 1 other utility. Here's what the water means for your fish.
Disinfectant
Chlorine or chloramine
Utilities here use chlorine or chloramine, depending on which one serves your address. Chlorine slowly gases off from standing water; chloramine doesn't.
Safety for fish and shrimp
Nitrate (NO₃)
Area estimate1.1–64 ppm (Worth knowing)
Typical 10 ppm
Water changes can't take your tank's nitrate below this level.
Area estimate from nearby wells: USGS well samples in your state (2000–2021).
Water chemistry
General hardness
Area estimate26–439 ppm
Typical 224 ppm
Hard. Ideal for livebearers and African cichlids. Soft-water species may struggle to breed.
Area estimate from nearby wells: USGS well samples in your state (2000–2021).
Carbonate hardness (alkalinity)
58–104 ppm
Typical 62 ppm
Moderate buffering. pH should stay fairly steady.
From EPA monitoring data; EPA monitoring data, measured before treatment (2012–2019).
pH
6.3–8.3
Typical 6.4
Acidic. Stable water matters more than the exact number.
From EPA monitoring data (2013).
Total dissolved solids
Area estimate105–666 ppm
Typical 313 ppm
A rough measure of everything dissolved in the water. RO water reads near 0, so TDS is a quick way to compare waters.
Area estimate from nearby wells: USGS well samples in your state (2000–2021).

Our data comes from public records and is still incomplete. Many utilities don't publish every number, so we're adding more all the time. Your city's range is a starting point: testing your own tap is the only way to know exactly what's in it.
