South Coventry, CT tap water
Supplied mostly by Ctwc - South Coventry System, plus 2 other utilities. Here's what the water means for your fish.

Chlorine
Your water is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it.

From EPA monitoring data (2012–2019).
Nitrate (NO₃)
0.3–2.7 ppm (Low)
