What This Means

Jefferson County, Alabama has hard water, estimated at 146 mg/L (PPM). Hard water causes noticeable mineral scale on faucets, showerheads, and inside water heaters. You may notice spots on dishes, stiff laundry, and dry skin or hair. A water softener is recommended to protect your plumbing and appliances.

What You Should Do

1

A water softener is recommended. At 146 ppm, scale buildup will affect your water heater, dishwasher, and plumbing over time.

2

Test your water with strips to confirm. Our estimate is based on USGS county data — a $5–15 test strip kit from a hardware store will verify your exact tap water hardness.

3

Consider a whole-house ion exchange system ($800–2,500). This will remove calcium and magnesium, protecting all appliances and making a noticeable difference in skin, hair, and cleaning.
