Frequently asked

Real questions homeowners ask us in the kitchen.

Most of LA County is served by LADWP from the Eastern Sierra Aqueduct or local groundwater. Documented contaminants of concern include chromium-6 (detectable at 0.1–0.4 ppb in many ZIPs), chlorination byproducts (TTHMs, HAA5s), arsenic in some inland water tables, and 280–500 mg/L hardness almost everywhere. Inland Empire adds perchlorate from aerospace legacy sites. Imperial Valley pulls from the Colorado River with much higher TDS and arsenic.

California's Office of Environmental Health Hazard Assessment set the public health goal at 0.02 ppb. LADWP regularly tests at 0.1–0.4 ppb in some service areas. Erin Brockovich made Hinkley famous because of chromium-6. We size a dedicated stage when our test shows detectable levels.

Whole-home: 4-6 hours typical. RO at the kitchen sink: 90 minutes. Most residential customers are using filtered water the same day they had the test done.
