Home, WA tap water

Supplied mostly by Cole, plus 1 other utility. Here's what the water means for your fish.

Disinfectant

Not confirmed

We couldn't confirm how your water is disinfected. US utilities use chlorine or chloramine, and chloramine doesn't gas off when water sits out.

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 (2012–2018).

Nitrate (NO₃)

Up to 2.6 ppm (Low)

Typical 2 ppm

Low, so water changes lower your tank's nitrate well.

From EPA monitoring data (2012–2019).

Water chemistry

General hardness

Area estimate

32–79 ppm

Typical 52 ppm

Soft. Good for tetras, rasboras and most shrimp. Livebearers, snails and African cichlids prefer harder water.

Area estimate from nearby wells: USGS well samples in your county (2000–2016).

Carbonate hardness (alkalinity)

Area estimate

35–81 ppm

Typical 59 ppm

Moderate buffering. pH should stay fairly steady.

Area estimate from nearby wells: USGS well samples in your county (2000–2016).

pH

Area estimate

6.3–7.9

Typical 7.3

Most community fish do well here. Stable water matters more than the exact number.

Area estimate from nearby wells: USGS well samples in your county (2000–2016).

Total dissolved solids

Area estimate

47–168 ppm

Typical 60 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 county (2000–2016).

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.
