The Water As Drunk in Washington

The Water As Drunk in Washington

Dr. R. B. Dole, of the United States Geological Survey, says that the water used at Washington, D. C. is harder than that of the New England States and softer than that used in the Missisippi Valley. He said that “if every person in Washington used a gallon of water a day in washing it would take $400 worth of soap to soften the water so it could be used.” The hardness is in the proportion of 112 parts to the million. In discussing the mineral properties of that city’s water he stated that “the total mineral matter in one day’s supply to the whole city can be represented by a block of stone about 6 feet square and 10 feet high, weighing 30 tons.” The water, he added, contains more mineral than that of “much-advertised mineral watering places. Hard water,” he pointed out, “is good to drink, but it is bad on the boilers in manufacturing plants. The mineral in the water is the prime object of having the filtration plant in Washington, but the amount of water used for drinking purposes is small compared with the amount used for laundry and manufacturing purposes.”
