New Britain, PA tap water
Part of New Britain is supplied by Aqua PA Chalfont, plus 1 other utility. Here's what its water means for your fish.
Disinfectant
Chlorine or chloramine
Utilities here use chlorine or chloramine, depending on which one serves your address. Chlorine slowly gases off from standing water; chloramine doesn't.
Safety for fish and shrimp
Ammonia (with conditioner)
Estimate0.11–0.24 ppm (Low)
Typical 0.18 ppm
This is what a conditioner frees when it breaks the chloramine apart. A cycled filter clears it within a day.
Estimated from the chloramine level Dtma Main System reports (2012–2019).
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 18 ppm (Low)
Typical 6.1 ppm
Water changes can't take your tank's nitrate below this level.
From EPA monitoring data (2012–2019).
Chlorine or chloramine at the tap
0.5–1.5 ppm
Typical 1.4 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.
From EPA monitoring data (2012–2019).
Water chemistry
General hardness
Area estimate71–291 ppm
Typical 168 ppm
Moderately hard. Great for livebearers, and most community fish adapt.
Area estimate from nearby wells: USGS well samples in your county (2003–2023).
Carbonate hardness (alkalinity)
111 ppm
Strong buffering. pH stays steady and hard to lower without RO water.
From EPA monitoring data (2016–2017).
pH
6.5–7.5
Typical 6.9
Most community fish do well here. Stable water matters more than the exact number.
From EPA monitoring data (2016–2017).
Total dissolved solids
Area estimate77–259 ppm
Typical 120 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 (2003–2023).

We couldn't fully map which utility serves New Britain. These numbers come from the utilities we matched, which serve about 33% of residents.
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.
