Waterssometimes contain limestoneto such an extent that whenboiled they become cloudy,which is because of the re-moval of the carbonic acid Fig. water filter. gas; this caused the limestone to remain in solution. Waters that contain limestone are not generally consid-ered injurious to health although theyare not so satisfactory for cleaning pur-poses on account of the lime acting uponthe soap and forming a scum of insolublelime soap. A large amount of lime-stone, gypsum, etc., is what causes watersto be hard. Some waters contain ironcompounds, as carbonate of iron which,upon contact with the air, forms hydrate of iron, and is deposited as a brownish red sediment. Some waters contain so much mineral matter that when.
