WATER POLLUTION CONTROL 



Stream pollution studies, now an integral part of modern fish and 

 wildlife management, were continued through 1955-56 by the Department in 

 cooperation with the Department of Health and other agencies concerned with 

 water-use . 



Forty-five field investigations, ranging from routine examinations 

 to detailed industrial waste and water studies, were made throughout the 

 Province. Close liaison with the Sanitary Engineering Division of the Depart- 

 ment of Health made it possible to rely solely on that Department for the 

 study of numerous other cases in which the fish and wildlife considerations 

 were of secondary importance. This division of responsibility made it 

 possible for the Department to direct much of its attention to Northern 

 Ontario v/here pulp and paper and raining wastes were of prime importance. 



Control of industrial pollution continues to be a long-range object- 

 ive in most cases. The tremendous costs of waste treatment and disposal equip- 

 ment, and the lack of the technical knowledge necessary to make control 

 measures feasible or recovery and utilization of wastes possible, are the 

 major obstacles to be overcome. Control of sewage pollution, on the other 

 hand, is primarily a financial problem and is being studied as such by other 

 Departments . 



The advice and active participation of field personnel in the Forest 

 Districts continues to form the basis for many investigations. The first-hand 

 knowledge which is applied in this way is an important contribution when 

 pollution control is considered in terms of Fish and Wildlife management, 

 and is a necessity when an evaluation of the effectiveness of pollution 

 control measures is to be made.
