FILTRATION Coxsackie, N. Y., is to have a filtration plant. Plans for a filtration plant at Weston, Ont., Can., have been made. A new pump for the Princeton, Ill., deep well is expected to be in operation May 1. Tests made of samples of the city water at Fond du Lac, Wis., show that it is in excellent condition and has no bacteria in it. A filtering plant now being constructed at Neillsville, Wis., will render available for domestic use the river water which has been heretofore unfit for human consumption. It has been found that the drinking water at Muskegon, Mich., has not been to blame for the epidemic of sickness which has been prevalent in that city and vicinity. State chemists have found that the water is pure, and its use is recommended.
