Tap water in Town and Country has about 234 mg/L of hardness, which is 13.7 grains per gallon. On the USGS scale that counts as very hard. TapWaterData worked it out from the calcium and magnesium levels the local utility reports (December 2020).
Town and Country sits 113 mg/L above the typical Missouri figure of 121. Of the 10 nearest cities we track, 8 have softer water and 2 have harder. The range nearby runs from 104 mg/L in Murphy to 263 in Des Peres.
What 234 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 234 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 × 13.7 gpg = 3,071 grains a day. A 24,000-grain unit regenerates about every 7 days.
EPA record for Town and Country's water system
We could not match Town and Country to a community water system in EPA's records. Your water bill or the yearly Consumer Confidence Report names the system and its ID.
