Bryan water measures 380 mg/L (22.2 gpg) of hardness, very hard by USGS standards. The number comes from Aqua Ohio - Norlick, dated December 2022.
At 380 mg/L, Bryan is 267 mg/L above the typical Ohio figure of 113. None of the 10 nearest cities we track has harder water. The range nearby runs from 49 mg/L in Piqua to 342 in Sidney.
What 380 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 380 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.
3 people × 75 gallons a day × 22.2 gpg = 5,000 grains a day. A 48,000-grain unit regenerates about every 9 days.
