The Supplement to EPA Compendium Method TO-15 provides guidance for reducing the method detection limit (MDL) for the compound 1,1-dichloroethene (1,1-DCE) and for other volatile organic compounds (VOCs) from 0.5 parts per billion by volume (ppbv), as cited in Method TO-15, to much lower concentrations. The MDL for 1, 1-DCE was determined to be 6 pptv. During the experimental effort, a capability for preparing 1, 1-DCE sample concentrations of 30 pptv and 60 pptv in ambient air was developed. Samples were prepared and sent to three contract laboratories as unknowns. Subsequent comparisons of results indicated close agreement among the laboratories while maintaining the performance standards for replicate precision (25%) and audit accuracy (30%) originally specified in Method TO-15. Since the different laboratories employed different analytical procedures, the use of a performance-based method appears justified.
