Basin City, WA tap water

Supplied mostly by Oakdell Farms LLC, 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 (2013–2017).

Nitrate (NO₃)

1.8–31 ppm (High)

Typical 31 ppm

High for tap water. Water changes can't take your tank's nitrate below this level.

From EPA monitoring data (2012–2019).

Water chemistry

General hardness

Area estimate

111–403 ppm

Typical 254 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 county (2000–2023).

Carbonate hardness (alkalinity)

Area estimate

132–354 ppm

Typical 184 ppm

Strong buffering. pH stays steady and hard to lower without RO water.

Area estimate from nearby wells: USGS well samples in your county (2000–2023).

pH

Area estimate

7.4–7.9

Typical 7.7

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 (2000–2023).

Total dissolved solids

Area estimate

245–629 ppm

Typical 410 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 (2000–2023).

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.
