La Mirada Water District delivers 290 PPM 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.
La Mirada's water is supplied by the La Mirada Water District. The local supply measures 290 PPM of hardness, classified as "Hard" — well above the 120 PPM threshold that defines hard water.
The utility also uses chlorine/chloramines at roughly 2 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 La Mirada homeowners.
Hard — anything over 120 PPM is considered hard water.
Used for disinfection — causes bad taste and dry skin.
Scale buildup on fixtures and water-using appliances.
