On May 13, 2005, the U.S. Environmental Protection Agency (EPA) chartered a Federal Advisory Committee on Detection and Quantitation Approaches and Uses in Clean Water Act Programs (hereafter referred to as the FACDQ or the Committee). The purpose of the Committee was to evaluate and recommend detection and quantitation procedures and uses ofthese procedures in Clean Water Act (CWA) programs. The Committee included 21 members representing EPA and five groups of stakeholders: laboratories, industry, publicly owned treatment works or POTWs, States,and environmental organizations. The final FACDQ meeting was held on December 21, 2007; the December 27, 2007, final FACDQ report is available at: http://water.epa. gov/scitech/methods/ cwa/det/index.cfm. Early in its work, the FACDQ reached agreement on 15 statements that described What We Need a Procedure to Do. As part of their assessment process, the FACDQ conducted a study (the FACDQ Pilot Study of 2006-2007) of three detection and three quantitation procedures and usedthe 15 statements as criteria for evaluation of these procedures. Study results indicated that one detection and quantitation procedure includedmost of the elements that FACDQ members had agreed needed to be incorporated into a procedure.
