Whole-home softening, filtration, and reverse osmosis drinking water for Whittier homes. Assessment first, equipment sized to your address.
Whittier has more than one water provider, so what reaches the tap genuinely depends on which utility serves your address. Suburban Water Systems' Whittier division draws from wells in the Main San Gabriel Groundwater Basin, and San Gabriel Valley Water Company, the City of Whittier's own water utility and Orchard Dale Water District each serve parts of the city as well.
The Main San Gabriel Basin has a long public record. Four areas of the San Gabriel Valley Groundwater Basin are EPA Superfund sites, with trichloroethylene, perchloroethylene and carbon tetrachloride as the primary contaminants, and perchlorate and 1,4-dioxane also documented. Groundwater from the basin drains south through Whittier Narrows into the Central Basin. Whichever utility bills you publishes an annual water quality report, and for a Whittier address that report is the document worth reading.
