During the past year, Rancho Water’s water hardness averaged 184 milligrams per liter (mg/L) (equal to 10.7 grains per gallon, 1 grain = 17.1 mg/L). This is considered “hard” water.

Rancho Water does not add fluoride to its water; however, fluoride occurs naturally in Rancho’s groundwater. Our local water supplies are “blended” with water imported from the Metropolitan Water District of Southern California (MWD). Rancho’s range is 0.7 - 1.3 milligrams per liter (mg/L). The maximum allowable level of fluoride at the state level is 2.0 mg/L.
There is more to water softeners than soft water. Softeners typically waste more water than they process because of the need to “flush” the softening system. In addition, softeners can release considerable salt by-products into wastewater treatment facilities and groundwater supplies, resulting in increased mineral levels.
