Is SMWD water hard or soft?

While it varies on the time of year and drought conditions, much of the water in Southern California including SMWD, is generally considered hard. Hard water means that it has higher levels of minerals, such as calcium and magnesium. These are naturally occurring minerals found in the Colorado River which is one of SMWD’s primary drinking water sources. The State Water Resources Control Board and the US Environmental Protection Agency both consider hard water only an aesthetic issue and is completely safe to drink.
