Leawood, KS tap water

Supplied by Water District 1 of Johnson Co. Here's what its water means for your fish.

Disinfectant

Chloramine

Your water is treated with chloramine. Unlike chlorine, it doesn't gas off when water sits out, and many pitcher and fridge filters aren't rated to remove it. Conditioners that list chloramine on the label break it apart, which frees a little ammonia. Some utilities switch to plain chlorine for a few weeks a year.

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 (2013–2014).

Nitrate (NO₃)

3.4–6.2 ppm (Low)

Typical 5.8 ppm

Water changes can't take your tank's nitrate below this level.

From EPA monitoring data (2012–2019).

Water chemistry

General hardness

Not published yet

We haven't found this number yet. A drop test kit gives you your exact reading.

Carbonate hardness (alkalinity)

54–62 ppm

Typical 58 ppm

Moderate buffering. pH should stay fairly steady.

From EPA monitoring data (2012–2019).

pH

9.2–9.3

Typical 9.3

Alkaline. Many utilities raise pH to protect pipes. Stability matters more than the exact number.

From EPA monitoring data (2012–2019).

  • Water District 1 of Johnson Co softens its water at the plant, so it may be softer than the local groundwater.

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.
