The National Water Quality Laboratory (NWQL) recommends a new procedure for using a syringe to add Volatile Organic Compounds (VOCs) to matrix spike samples. On-site and laboratory studies comparing the use of syringes and micropipets for spiking water samples with VOCs were conducted by the NWQL and the National Water Quality Assessment (NAWQA) Program.

This memo describes the laboratory quality-control (QC) sample information available for district use in interpreting the results of determinations of organic substances in environmental samples. The general quality-assurance (QA) practices for analytical activities used by the National Water Quality Laboratory (NWQL) are outlined in Pritt and Raese (1992).
