DETROIT WATER SUPPLY.
The report of the Board of Health of Detroit, Mich., says: “Detroit may be said to have been more fortunate than otherwise in having limited typhoid to the present rate when all circumstances are considered. That the element of fortunate circumstances may not be overloaded, due attention should be directed toward the purification of the present water supply.” When Dr. W. H. Price, health officer, was asked how the safeguarding of the health of the people was to be accomplished, he replied by installing a filtration system. Ihe present lime treatment is only a temporary expedient. It might prove entirely ineffective in the event of extremely heavy pollution of the water, and the ultimate safeguard against this threatened heavy pollution is a filtration plant. This recommendation seems rational especially when it is considered that lake waters generally require filtration as they are polluted within certain zones and as the pollution extends so has the zone from winch good water may be taken. The most effective method in such a case as Detroit to procure pure water is to filter it.
