The 1986 Amendments to the Safe Drinking Water Act begin a new period of water quality management for water utilities. Of particular concern to water utilities depending upon surface sources are amendments that regulate more contaminants, define treatment techniques for each contaminant regulated, and require filtration and chlorination of surface supplies with few exceptions. As the National Primary Drinking Water Regulations and their allowable associated Maximum Contaminant Levels decrease, drinking water utilities will be under pressure to install new treatment techniques. In order to prevent a constant 'crisis' situation and to implement treatment plant design decisions, knowledge of the type and concentration of pollutants that can be reasonably expected to occur in each specific area is necessary.
