Pharmaceuticals in Drinking Water
Yorba Linda Water District is committed to public health and safety and works hard to ensure that your drinking water is the safest it can possibly be.
The presence of pharmaceutical and other personal care products in water is not new and the health and safety impacts have been studied for many years. Recently, advances in laboratory technology have made it easier to detect and measure them at extremely low levels. The fact that a substance is detectable does not mean the substance is harmful to humans drinking average amounts of water. Additional research is needed to determine which pharmaceuticals and personal care products pose a risk, if any.
Hard Water
Water is considered to be "hard" when it contains naturally occurring minerals in suspension. Water has been described as the "universal solvent" - meaning that water dissolves anything it comes in contact with. Yorba Linda Water District's major sources of water are the Colorado River and local groundwater. Both of these sources contain the minerals calcium and magnesium. The white spots you see on a glass on which water has dried are small deposits of these minerals.
Water hardness is a function of geology - if the water flows through mineral bearing materials, it will "pick-up" some of those minerals. Water from the Orange County Aquifer and from the Colorado River contains calcium and magnesium, which is what leaves white spots on drinking glasses. These minerals are not harmful, and are found in most multi-vitamins. Water from northern California is softer, but we don’t regularly get much of this water in Orange County.

Fluoride
Yorba Linda Water District does not add fluoride to your water. Naturally occurring fluoride is present in the water, but not at a level that provides dental health benefits.
In 1995, the California Legislature passed a bill mandating that all large water agencies fluoridate their supplies, but only if the state or "somebody" provided the agencies with the money to do so.
To date, the state has not come up with the funds to implement fluoridation. Metropolitan Water District of Southern California (MWDSC) commenced fluoridation of southern California's drinking water supply at the end of 2007.

YLWD purchases approximately half of its water from MWDSC. Because of MWD’s decision and YLWD’s dual sources of water, some of its customers will get water fluoridated by MWD, some will get non-fluoridated water, and some will get a blend of fluoridated and non-fluoridated water.
During certain periods when import water is more economically available than groundwater sources, areas traditionally supplied with currently non-fluoridated water will temporarily receive fluoridated water supply from MWDSC.
