That's an unusual combination: very hard water plus trace contaminants that made the utility invest in treatment. Home filtration addresses both sides at your meter.
Why the Utility's Treatment Isn't the Whole Answer
EVMWD's arsenic treatment for Elsinore Basin wells and its ongoing PFAS work are serious infrastructure investments, and they do their job at the source. But treatment plants manage the supply; they don't change what hardness does inside your home. At nearly 20 grains, scale attacks water heaters, dishwasher elements, and fixtures regardless of how well the trace contaminants are handled upstream.
Our whole-home water filtration designs account for the actual blend reaching your neighborhood — which shifts as the imported-to-well ratio changes through the year. Multi-stage systems combine sediment pre-filtration, carbon for taste and chemicals, and softening for the hardness. Homes in the Lake View District with older plumbing often see the most dramatic change, since decades of scale finally stop accumulating.
Hardness Damage in Real Terms
Nineteen-grain water doesn't negotiate. We drain water heaters in Canyon Hills with sediment beds inches thick, replace shower cartridges in Lakeland Village annually instead of decadally, and descale faucet aerators that clog within months. The spots on dishes, the stiff laundry, the white crust on every fixture — that's all the same mineral load, and it costs real money in shortened appliance life.
A softener stops it at the entry point. And because softened water lets soap and detergent work properly, most households in the area end up using less of both — a small but real offset against the system's salt and water use.

Frequently Asked Questions
**Is there arsenic in Lake Elsinore's water?**
Arsenic occurs naturally in the Elsinore Basin groundwater, which is why EVMWD built dedicated arsenic treatment for its basin wells. Treated water meets drinking water standards, and homeowners wanting additional protection install home filtration with media rated for arsenic reduction.
How hard is Lake Elsinore water? EVMWD's 2025 reporting showed average groundwater hardness around 338 parts per million — roughly 19.8 grains per gallon, firmly in the very-hard range. The blended water at your tap varies with the imported-to-well ratio, but hardness remains high year-round.
What's the difference between the imported water and the well water? About 65 percent of the supply is imported MWD surface water — softer, but treated with disinfectants that affect taste. The local groundwater is harder and carries the basin's mineral and trace-contaminant profile. Your tap gets a blend that shifts seasonally, which is why we test before designing a system.
Do I need a filter, a softener, or both? For Lake Elsinore, usually both. Filtration addresses taste, sediment, and trace-contaminant concerns; only ion-exchange softening removes the hardness minerals behind the scale. A combined system is the standard recommendation for this water profile.
