What hard water is doing to your home right now
At 17 GPG, Santa Clarita has some of the hardest water in LA County — plus PFAS levels that rank near the top statewide. Here's what that means for your home every single day.
Scale & plumbing damage
Mineral buildup inside pipes shortens appliance life and reduces water flow over time.
Spots on dishes & glass
Hard water leaves white mineral residue on every surface it touches when it dries.
Dry skin & dull hair
Hard minerals strip natural oils from skin and hair every time you shower.
PFAS contamination
SCV ranks top 10 statewide for PFAS — forever chemicals linked to serious long-term health risks.
Premature appliance failure
Water heaters fail 50% sooner. Dishwashers and washing machines degrade faster with hard water.
Taste & odor issues
Chlorine, arsenic traces, and dissolved minerals affect every glass from your tap.
