County estimate

Water samples from around Atlantic City put hardness at about 12 mg/L (0.7 gpg), which would be soft on the USGS scale. Treat this as a rough guide: it is the median of 574 samples taken across Atlantic County, mostly wells and streams, not a test of Atlantic City's treated tap water.

What 12 mg/L means at home

Soap and shampoo lather with very little product. Kettles and showerheads stay mostly free of white crust.

Some people notice that soap feels slow to rinse off in soft water. That slippery feel is normal and harmless.

Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.

What to do about it

Nothing, as far as hardness goes. At 12 mg/L a softener would have almost nothing to remove.

Carbon filter

If the water tastes of chlorine, a pitcher or faucet carbon filter takes care of that. It does not change hardness.

EPA record for Atlantic City's water system

We could not match Atlantic City to a community water system in EPA's records. Your water bill or the yearly Consumer Confidence Report names the system and its ID.
