County estimate

Water samples from around Sanford put hardness at about 50 mg/L (2.9 gpg), which would be soft on the USGS scale. Treat this as a rough guide: it is the median of 102 samples taken across Lee County, mostly wells and streams, not a test of Sanford's treated tap water. One more reason for caution: EPA lists Sanford's water system as using surface water, which is often softer than the wells behind the county figure.

What 50 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 50 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.
