Memo - The SMRI File Selection of Third Party Contractor & Lab page 3 results and prepare a summary report of eac~ sampling tour. Dr. Mae estimates the total cost for her prz-sampling analysis and seven tom lete sampling rounds to be 523,736, plus the direct expenses of sample an lysis to be passed through to BMRI. Sherman J. Worthington, P.E. and Phillip L. Leonhardt, P.E., represe ted Waste, Water & Land, Inc. in the intervie~.v and coauthored the writte proposal. Messrs. Worthington and Leonhardt have extensive experien a in mine project engineering and water quality monitoring and sampling. W,WF~ also proposes to involve Ms. Elaine Donner, P.E. in the field sampling ac ivity. Ms. Donner has experience in hydraulic and traffic engineering. W,W L proposed to complete a pre-sampling review of the approved sampling nd analytical protocols established by BMRI in TR-006 prior to the firs sampling round. W,W&L then proposes to complete the required sampling oversi e, sample preparation and delivery to the laboratory, and to review the analytical results and prepare a summary report of each sampling tour. Messrs. Worthington and Leonhardt estimate the totai cost for their pre-sampling analysis and seven complete sampling rounds to be 525,160, plus the irect expenses of sample analysis to be passed through to BMRI. Based upon the proposals submitted, both nominees are capable of pro iding the required services to complete third party monitoring of the San Luis site. Neither firm has direct experience in Cyanide sampling. The principle difference between the nominees lies in the involved profzssicnais' ethnical training. Dr. Maest is a hydrochemist / geochemist, Me r rs. Worthin ton and Leonhardt and Ms. Donner are civil encineer; / hydrologists. All ap ear experienced and qualified in ~.vatzr sampling and em~ironmental monitoring. Dr. Maest's job experience has stressed the specific evaluation of envir nmental monitoring programs design and protocol methodology. W,W&L's involy d professionals have routinely concentrated upon the project operation 1 design, with specification of monitoring programs to comply with regulatory requirements. Dr. Posey and I anticipate that problems wh'ch might be encountered wring the third party monitoring will most likely relate to specific hydrochemical and geochemical aspects of ~.vater quality analys'>, in which case we susp ct Dr. Maest ~.vould be more qualified to identify ant remedy sampling-relate data accuracy and reliability proolems. Similar _~ the nominees for ana~~tical laboratory, these two nominees are both qua "tied and capable. In m~ experience, this is an enviable position to ce in. RCG/Hagler, Bailly, Int.'s projected test is 6.0 percent less than Was .z, 1•later ~ Land, Int.'s, a relatively minimal difference. However, in _onsideraticn of the tom ination of slightly lower projected cost, the assign-ent of a single professional, and the opportunity to benefit from specific tecanical qualifications an experience of that individual, it i; my conc'usion that RCG/Hagler, ai11y, Inc. is the preferred contractor to provide 'hz "third party samplin " services we desire.
