The four volumes in this set comprise the working guideline documents for the Love Canal Study. The documents were developed to direct both the prime contractor and subcontractors while performing for the Environmental Protection Agency. Detailed procedures for each analysis type are described. Procedures for all field sampling are also described. Quality assurance plans submitted by each subcontractor and approved by the prime contractor are provided. A description of the document control procedure, chain-of-custody procedure, various quality control procedures, and other study operational procedures are provided. Together the four documents provide a 'work plan' for the Love Canal effort. Since the volumes were developed prior to the actual field sampling, no environmental results are included. This volume discusses chemical analysis procedures on the environment.
