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.
