76 -- THE SERVICES REQUIRED TO WRITE AN ENGINEERING PAMPHLET FOR THE OPERATION AND MAINTENANCE OF EXTRACTION AND INJECTION WELLS AT HAZARDOUS, TOXIC AND RADIOACTIVE SITES. DUE 072198 POC Contract Specialist, Mel Vogt 402-221-4298 WEB: Omaha District Contracting Division Homepage, http://ebs.nwo. army.mil/EBS/CONTRACT.HTM. E-MAIL: Mel Vogt, Mel.E.Vogt@usace.army.mil. The Government proposes to award a sole source procurement action to ARCC Inc., of Daytona Beach Florida. The services required are to write an Engineering Pamphlet for the Operation and Maintenance of Extraction and Injection wells at Hazardous, Toxic and Radioactive Waste sites. The Engineering Pamphlet will provide guidelines and checklists for designers to use to develop or scope an O&M Plan for wells at sites during the design phase of projects. The plan shall allow for site-specific variables in geology, hydrogeology, aqueous geochemistry and contaminant specification and concentration information to be incorporated. The plan will include designs that prevent bio-fouling and mineral encrustation in both injection and extraction wells. In order to develop an effective O&M plan, the offeror must have hands-on experience, knowledge, and skill in managing and resolving a combination of geology, biochemistry, chemical, and hydro-geological problems involving bio-fouling and CERCLA requirements. The offeror, to provide an effective plan, must have an understanding of a combination of geology, biochemistry, chemical and hydro-geological problems involving bio-fouling. The offer must also have detailed knowledge on the blending of chemicals that effect the cleaning of wells, to include organic acids, sequestrants, chelating agents and wetting agents. The blending of the chemicals must be versatile enough to meet the site-specific waters. The chemicals to be used must also be able to penetrate the aquifer formation as well as the filter pack of the wells to kill bacteria, dissolve and mobilize mineral encrustation so that they may be removed from the wells.
