South Woodstock, CT tap water
Supplied mostly by Putnam Water Pollution Control Authority, plus 6 other utilities. Here's what the 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)
Up to 9.1 ppm (Low)
Typical 2.6 ppm
Low, so water changes lower your tank's nitrate well.
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)

Little buffering. pH can drop quickly between water changes, especially with CO₂ or an older tank.
From EPA monitoring data, measured before treatment (2012–2019).
pH
6.7–8.9
Typical 7.7
Most community fish do well here. Stable water matters more than the exact number.
