Water Quality Reports
Yorba Linda Water District publishes an annual “Consumer Confidence Report” in compliance with state and federal law. If you have any questions or need further information please contact our Water Quality Division at (714) 701-3000 or email us at waterquality@ylwd.com.

Additional Water Quality Topics
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, found in most multi-vitamins, are not harmful. 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 its groundwater supplies. Naturally-occurring fluoride is present in the aquifer.
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 funds to do so. To date, the state has not come up with the funds to implement fluoridation.
Metropolitan Water District of Southern California (MWD) commenced fluoridation of the drinking water it supplies to Southern California in November of 2007. The District purchases approximately 30% of its water from MWD. Because of MWD’s decision and YLWD’s dual sources of water (groundwater and import), YLWD is faced with a situation where some of its customers will receive water fluoridated by MWD, some will receive non-fluoridated water, and some will receive a blend of fluoridated and non-fluoridated water.
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.
