Wylie water measures 126 mg/L (7.4 gpg) of hardness, hard by USGS standards. The number comes from Bear Creek SUD, dated June 2023.
At 126 mg/L, Wylie is 14 mg/L above the typical Texas figure of 112. Of the 10 nearest cities we track, 5 have softer water and 3 have harder. The range nearby runs from 90 mg/L in Fairview to 164 in Sachse.
What 126 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 126 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 × 7.4 gpg = 1,658 grains a day. A 24,000-grain unit regenerates about every 14 days.
