Sharon, MA tap water

Supplied by Sharon Water Dept. Here's what its water means for your fish.

Disinfectant

Chloramine

Your water is treated with chloramine. Unlike chlorine, it doesn't gas off when water sits out, and many pitcher and fridge filters aren't rated to remove it. Conditioners that list chloramine on the label break it apart, which frees a little ammonia. Some utilities switch to plain chlorine for a few weeks a year.

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 (2014–2017).

Nitrate (NO₃)

4.4–18 ppm (Worth knowing)

Typical 13 ppm

Water changes can't take your tank's nitrate below this level.

From EPA monitoring data (2012–2019).

Water chemistry

General hardness

Area estimate

38–70 ppm

Typical 49 ppm

Soft. Good for tetras, rasboras and most shrimp. Livebearers, snails and African cichlids prefer harder water.

Area estimate from nearby wells: USGS well samples in your county (2001–2019).

Carbonate hardness (alkalinity)

Area estimate

13–25 ppm

Typical 24 ppm

Little buffering. pH can drop quickly between water changes, especially with CO₂ or an older tank.

Area estimate from nearby wells: USGS well samples in your county (2001–2019).

pH

Area estimate

5.9–6.3

Typical 6

Acidic. Stable water matters more than the exact number.

Area estimate from nearby wells: USGS well samples in your county (2001–2019).

Total dissolved solids

Area estimate

124–212 ppm

Typical 182 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 (2001–2019).

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.
