Why Riverside Homes Need Water Treatment
Local water quality, hardness levels, and supply sources make water treatment a smart investment for Inland Empire (Riverside–San Bernardino)-area homeowners.
The Inland Empire — California's massive metro spanning Riverside, San Bernardino, Ontario, Corona, Rancho Cucamonga, and surrounding communities — draws its water from local groundwater basins fed by alluvial deposits and sedimentary rock. Riverside Public Utilities reports average hardness of 194 mg/L (11 GPG) with TDS averaging 350 ppm. Some areas of the Inland Empire see TDS approaching 590 ppm — above the EPA's 500 ppm secondary guideline. Important note: certain California communities restrict salt-based water softeners due to brine discharge concerns. Salt-free water conditioners and reverse osmosis systems are available alternatives.
