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. Syringes were found to yield significantly improved recoveries and variabilities for fortifying ground- and reagent-water samples in comparison to the micropipets currently in use. No significant disadvantages were reported or observed with the syringe selected for on-site use.
