County estimate

Water samples from around Brunswick put hardness at about 247 mg/L (14.4 gpg), which would be very hard on the USGS scale. Treat this as a rough guide: it is the median of 477 samples taken across Medina County, mostly wells and streams, not a test of Brunswick's treated tap water.

What 247 mg/L means at home

Scale forms fast here. Kettles and coffee makers need regular descaling, and showerheads clog unless you clean them.

Tank water heaters collect mineral sediment that insulates the water from the burner, so flushing the tank matters more than usual.

Dishes and glass shower doors spot easily. Soap scum and a dull film on hair or laundry are common complaints.

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 247 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 Brunswick

3 people × 75 gallons a day × 14.4 gpg = 3,249 grains a day. A 24,000-grain unit regenerates about every 7 days.
