County estimate

Water samples from around Lockport put hardness at about 167 mg/L (9.8 gpg), which would be hard on the USGS scale. Treat this as a rough guide: it is the median of 226 samples taken across Niagara County, mostly wells and streams, not a test of Lockport's treated tap water. One more reason for caution: EPA lists Lockport's water system as using surface water, which is often softer than the wells behind the county figure.

What 167 mg/L means at home

Expect white crust on faucets and showerheads, plus spots on dishes that come out of the dishwasher.

Kettles collect scale quickly. Water heaters build up sediment at the bottom of the tank, which makes them work harder over time.

Soap and detergent need a little more to lather, and soap scum shows up in the tub.

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

At 167 mg/L most of the trouble is scale, and only a few things deal with it.

Ion-exchange water softener

The standard whole-house fix. It swaps calcium and magnesium for sodium or potassium and needs salt plus a drain. Size it with the calculator below.

Salt-free conditioner

No salt and no drain line. It changes how minerals form scale instead of removing them, so water still tests hard.

Reverse osmosis or carbon filter

Under-sink reverse osmosis removes minerals from drinking water only. Plain carbon filters improve taste but do not soften.

Softener size for Lockport

3 people × 75 gallons a day × 9.8 gpg = 2,198 grains a day. A 24,000-grain unit regenerates about every 10 days.
