F Comprehensive Capabilities and Services Offered Initial Review of Current and Historical Site Data o Perhaps the most difficult aspect of a bioremediation project is the initial determination of what information is required, what the specific purpose and uses of the data will be, and the parameters which should be evaluated so that technically-sound decisions are made regarding costs, applicability and/or the efficacy of a desired bioremedial investigation or approach. X14 On initial contact, we generally request that the client provide us with historical site informa- tion and proposed activities to make initial interpretations of project parameters (i.e., analyti- cal results, past:Itreatments). This preliminary review will allow Biologic to become familiar with the project in order to identify potential problem areas, and attain comparative back- ground data soithat recommendations can be made. The.appropriate review of project data typically allows'�BioLogic to develop a comprehensive plan of feasible options and alterna- tives, costs, and'generally can provide the information needed to assist our clients in develop- ing workplan and in regulatory/client interactions. General Project Information Review Prior to project' initiation, it is very important that the Biologic team member assigned to your site becomes familiar with any available data you may have.
