B -- COLLABORATIVE VALIDATION OF SEVEN 1600-SERIES TRACE METALS METHODS SOL 97-1 DUE 042597 POC Sherry F. Lutz, Contracting Officer, (202) 260-1980 E-MAIL: click here to contact the contracting officer via e-mail, lutz.sherry@epamail.epa.gov. The U.S. Environmental Protection Agency has a requirement for six to eight qualified laboratories to validate seven 1600-series trace metal analytical methods for measuring at or near Water Quality Criteria (WQC) levels. Interested parties must prequalify to participate in this study. To prequalify, a bid, along with the following information must be provided: a) method blank results and method detection limit (MDL) b) specification of which methods (Methods 1631, 1632, 1637, 1638, 1639 and 1640) and matrices are being bid on. Bids to run fewer than seven methods, or to analyze either one, three, or all four matrices (ambient water, effluent, and reagant water matrices, or the marine matrices, or both sets) are acceptable. Laboratories shall not be permitted to analyze the ambient water, effluent, or reagent water matrices alone; these matrices must be analyzed as a set. Offerors shall perform instrument calibration that will encompass the minimum level specified. During the prequalification phase, laboratories are required to follow all QC procedures defined in the methods to be validated, with the following exceptions: 1) demonstration of initial and ongoing precision and recovery; 2) performance of matrix spike (MS) and matrix spike duplicate (MSD) analyses; 3) analysis of field blanks and equipment blank. Simplified acquisition procedures shall be utilized in selecting qualified laboratories. Written inquiries may be submitted via facsimile at 202/260-6866 or via E-mail to lutz.sherry@epamail.epa.gov.
