How hard is the water in Crystal Lake?
The raw ground water can be anywhere from 15-30 grains of hardness. The Water Division softens the water down to the 4-8 grain range. There are five separate water treatment facilities, which can yield small differences in hardness. This may also change slightly with seasonal adjustments depending on overall water demand. If overall demand reaches excessively high levels (8 million gallons per day) the Water Division will start increasing hardness to keep up with the demand. However, at all times, the hardness range that the City provides should eliminate any major hard water effects, such as excessive hardness deposits or difficulty lathering soap.
