NO TELEPHONE CALLS REQUESTING A SOLICITATION WILL BE ACCEPTED OR ACKNOWLEDGED. THIS SOURCES SOUGHT ANNOUNCEMENT MAY OR MAY NOT RESULT IN A SOLICITATION. The U.S. Department of Energy (DOE) is performing a market search for contractors with INNOVATIVE, IMPROVED FIELD METHODS FOR IN SITU DELINEATION AND ASSESSMENT OF CONTAMINATION LOCATED IN DIFFICULT SUBSURFACE CONDITIONS that occur at numerous DOE Nuclear Complex sites. This market search is focused on Dense Nonaqueous Phase Liquids (DNAPL) contamination (carbon tetrachloride, trichloroethylene, tetrachloroethylene, and others) in difficult subsurface conditions, and improved, more cost-effective technologies that operate in these difficult conditions to assess contamination. In these difficult conditions, the need is to improve detection of contamination, to improve measuring concentration levels in the field, and to improve mapping plumes (spatial distribution of contaminants) and time-variant changes. Novel and breakthrough field technologies that do not duplicate existing methods are desired. DOE Nuclear Complex Sites such as Hanford, Paducah, Portsmouth, Pantex, Savannah River, and Oak Ridge, all have DNAPL plumes that contaminate soil and groundwater in subsurface conditions that hamper assessment of contamination. These conditions include: soils that are difficult to penetrate; complex sediment facies; contamination that underlies man-made structures; excessively deep contamination (greater than 45m); and others. For example, at the Hanford 200 West Area, carbon tetrachloride (CCl4) is present in the vadose zone and groundwater. The vadose zoneand unconfined aquifer consist of a thick accumulation of unconsolidated to semi-indurated sediments composed of silts, sands, and gravels. The water table is located at about 65 m, and groundwater flows within a multi-aquifer system. Between 1955-1973, CCl4 was discharged to the soil column in this area in aqueous mixtures and in nonaqueous phase (DNAPL). The plume of dissolved CCl4 that resulted from these discharges, extends over 11 square km in the unconfined aquifer under 200 West Area. The highest concentrations of CCl4 in the 200 West Area groundwater are approximately 8,000 g/L. Dissolved CCl4 has been observed deep within the unconfined aquifer (>10 m below water table) and within the uppermost confined aquifer. Difficult conditions that hamper assessment of the plume in the 200 West Area include the complex sediment facies that control fluid transport, gravel lenses, well-cemented caliche layers, man-made obstructions (buildings, tanks, others), and extensive and deep contamination. Costs to characterize this deep and large plume with conventional technologies such as drilling and sampling are excessive, and significant cost-savings could be realized with improved methods. Contractors with innovative and breakthrough technologies that fulfill the following criteria are encouraged to submit the specified information for this market search. The technologies must have completed bench scale tests, proof of concept tests, and/or preliminary field tests, and have results available to assess the technology's performance, operating requirements, Environmental, Safety and Health (ES&H) factors, and regulatory issues. Qualifying technologies can be a combination of technologies integrated together, and should be capable of meeting all the identified field performance requirements. Expeditious field demonstrations at DOE sites that include Hanford would be desired for qualifying technologies, and a full scale demonstration at DOE Hanford is anticipated. To that end, the following are anticipated performance requirements that would be required for a full-scale demonstration at a Hanford 200 West demonstration site to assess CCl4 contamination in difficult subsurface conditions: (1) Ability to access and determine CCl4 concentration levels in vadose zone (soil vapor, soil moisture, sorbed to solids, and residual) and groundwater in difficult subsurface conditions that include complex sediment facies, gravel, caliche, beneath man-made obstructions, and depth greater than 85m. Must be capable of measuring CCl4 levels in groundwater ranging from maximum of 10,000 g/L CCl4 to minimum of 5 g/L CCl4. CCl4 may occur in both aqueous phase and free phase (DNAPL). (2) Capable of depth profile measurements ranging from the surface to depths of approximately 85m and capable of making measurements at multiple depths at discrete points on scale of several centimeters. (3) Ability to provide real-time measurements and data results are desired. Technologies that take advantage of existing extraction, injection, or monitoring wells, would be permitted. (4) Ability to map discrete lenses and pools of variable concentrations within the entirety of the plume. Methodology may involve integration of techniques, therefore integrated results would be desired within 48 hours. (5) Ability to measure time-variant changes of the combined plume configuration (spatial distribution) and the concentration levels. (6) Non-invasive or minimally invasive, eliminate or reduce Investigative Derived Waste (IDW), and prevent cross-contamination. For example, use of sensors in existing wells, use of geophysical or other remote sensing technologies, and methodologies involving cross-hole tests reduce or eliminate IDW. (7) Robust in order to operate in remote, harsh field environment where access is limited and utilities are not readily available. (8) Ability to provide technology performance and results which are verifiable with independent field data, controlled tests, or other acceptable means. (9) Ability to minimize operational time including rapid site mobilization, completion of operations, and demobilization. The technology should operate reliably, with minimal scheduled or unscheduled outages for maintenance or repair. (10) Completion of site training requirements and necessary security clearance requirements by personnel involved in installing/operating equipment at the selected demonstration site. (11) Demonstrated cost savings compared to baseline drilling and sampling methods, and able to operate within acceptable Hanford Environmental, Safety, and Health requirements, and regulatory and stakeholders requirements. (12) Demonstrated benefits to DOE (superior technical performance, reductions in cost, schedules, and risks to workers, the public, and the environment) and be acceptable to end-users at multiple sites within the DOE Complex. DOE HAS INTEREST IN RECEIVING INFORMATION CONTAINING PROOF OF CONCEPT TESTING OR PRELIMINARY FIELD TESTING OF TECHNOLOGIES THAT ARE NOVEL, BREAKTHROUGH FIELD METHODS THAT COULD MEET THESE REQUIREMENTS AND ARE NOT DUPLICATIVE OF EXISTING TECHNOLOGIES. ANY INTERESTED FIRM WITH A TECHNOLOGY THAT COULD FULFILL THESE REQUIREMENTS, SHOULD SUBMIT A BRIEF CAPABILITY STATEMENT (MAXIMUM 10 PAGES). STANDARD COMPANY BROCHURES ARE NOT DESIRED. INFORMATION SHOULD FOCUS ON RESULTS FROM ANY PREVIOUS TESTING ALONG WITH THE CAPABILITY TO PROVIDE THE TECHNICAL SERVICES IDENTIFIED ABOVE. A TEMPLATE OF A SUGGESTED FORMAT FOR SUBMITTAL OF YOUR CAPABILITY STATEMENT, AND REFERENCE(S) ARE PROVIDED AT http://www.netl.doe.gov/business/solicit/ PLEASE INCLUDE YOUR SMALL BUSINESS CONCERN STATUS, UNDER SIC CODE 8731, IN YOUR CAPABILITY STATEMENT. DO NOT INCLUDE PROPRIETARY AND/OR BUSINESS CONFIDENTIAL DATA. THE DEADLINE FOR SUBMISSION OF THE CAPABILITY STATEMENT IS June 13, 2000. Five (5) copies of this document should be submitted to Karen Cohen, U.S. DOE/NETL, P.O. Box 10940, 626 Cochrans Mill Road, Pittsburgh, PA 15236. A Site Visit to DOE Hanford, Washington is planned for late June, 2000 for firms interested in observing field conditions in which technologies must operate. The Hanford Site Visit will be contingent on interest. Contact Karen Cohen (via e-mail at "cohen@netl.doe.gov" ) by no later than May 22, 2000 and indicate interest to attend by providing visitor name, company affiliation, and visitor citizenry as U.S. Citizen or as Foreign National (and country of citizenry). Upon confirmation of the Site Visit, notification will be provided to those that respond, and all visitors will be required to pre-register. Site Visit registration information will be provided at that time and will include date, time, location, and registration form to submit.
