Water Purification and Laboratory Control

Water Purification and Laboratory Control

A certain amount of control must be exercised over all water supplies whether ground or surface in their nature and the extent and method of this control must largely he guided by the circumstances of the water works, its situation and its susceptibility to pollution.

The problem as to the best method of such supervision is one that must be settled by the superintendent of the water department in each instance. In this issue. Professor Jack J. Hinman, who is a well known authority on the subject of water purification, suggests the feasibility and in fact the practical necessity of laboratory control for water supplies to avoid pollution. He goes into the subject very deeply and emphasizes various advantages that accrue from this method of determining the purity of the water supply. His ideas on the subject are worthy of careful study.
