City of Colton Water delivers 380 PPM extremely hard water to your home. Our whole-home filtration systems remove hardness, chlorine, and scale — for softer skin and better-tasting water from every tap.
Colton's water is supplied by the City of Colton Water. The local supply measures 380 PPM of hardness, classified as "Extremely Hard" — well above the 120 PPM threshold that defines hard water.
The utility also uses chlorine/chloramines at roughly 2.4 mg/L for disinfection. While safe to drink, these leave a chemical taste and odor and can dry out skin and hair. The high mineral content causes scale buildup on fixtures, glassware, and appliances — the most common water complaint we hear from Colton homeowners.
Extremely Hard — anything over 120 PPM is considered hard water.
Used for disinfection — causes bad taste and dry skin.
Very hard groundwater mix causing heavy scale.
