Williamsport, PA tap water

Supplied by Williamsport Mun Water Auth. Here's what its 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)

2.3 ppm (Low)

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

From EPA monitoring data (2012–2019).

Chlorine or chloramine at the tap

0.6–1.3 ppm

Typical 1.1 ppm

At tap levels, chlorine and chloramine are toxic to fish, shrimp and the bacteria in a filter. Water conditioners are made for this range.

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.
