Utilities that use surface water supplies should measure planktonic algal chlorophyll as a raw water quality parameter on a routine basis. Chlorophyll measurement can be a viable substitute for the more costly and tedious algal counting method used by many utilities. A simplified procedure for chlorophyll measurements is presented, and suggestions are made on how water utilities can correlate the results of these analyses with raw water quality parameters of importance to them. Chlorophyll measurements of the lake or impoundment at or near the water supply intake can provide guidance as to the depth at which the water should be taken from the body of water in order to optimize raw water quality and reduce the cost of treatment.
