The source area on base where the contamination is located is commonly referred to as Operable Unit 2, formerly known as Chemical Pit 3. The site, located north of the golf course, consists of two trenches in which thousands of gallons of solvents were dumped during the 1960s and 70s. Consequently, the solvents pooled in a clay area approximately 50 feet below the surface. v ' " ' Nsx C '9s. "vs , kx '0VfX V i : ri iTTlJi irk' - ii 'V .

Environmental professional will tour the site Wednesday. in The new technology thats being at Hill, technically referred to as Surfactant Enhanced Aquifer Remediation, is already showing a lot of promise. Although it was tested here in the past on a small scale, this use of the marks the first large-scal- e technology anywhere. The surfactant-floo- procedure, d which began earlier this month, basi-showcas- ed cally involves pumping water and a substance into the ground detergent-lik- e to free trapped solvents imbedded ia the soils pore spaces. In addition, a Source Recovery System compliments the surfactant remediatipn process by pulling the solvents and contaminated water from the soil beneath the site. Ideal geologic conditions have made Hill a prime location to test the effectiveness of such technologies. Early reports indicate it will be extremely successful. We knew where the source area for the problem was located but this is the first time we were able to determine the volume and extent of the contamination in the source area, said Jon Ginn, Environmental Managements technical project manager for innovative technologies.. Ginn is optimistic the surfactant technology will substantially accelerate the amount of time it would have otherwise taken to capture the solvents from the source area. Its expected to take several more .weeks before all the data is collected, Ginn said, but the potential now exists for us to capture more contamination in a few months that previously would have taken several decades or longer. The United States Air Force Announces a Proposed Final Environmental Assessment for the Chaff and Flares at the Proposed Expansion of the use of Utah Test and Training Range, Utah Self-protectio- n The Environmental Management Directorate, Ogden Air Logistics Center, Hill Air Force Base (HAFB), UT, announces the availability of an Environmental Assessment (EA) and proposes a Finding Of No Significant Impact (FONSI) for the ' proposed action. Present imitations on the use of chaff and flares do not permit full development of the skills that pilots need for success and survival in modern air combat. The total amount of chaff and flares deployed within the UTTR would not change, however, the land are over which chaff is allowed would increase. The proposed action will reduce the number of chaff bundles deployed per acre within the areas overlain by UTTR airspace. ; Based on the findings of this EA, the proposed action would not have significant adverse effects on the human environment or on any of the environmental resources described in the EA. Therefore, a FONSI may be issued, and preparation of an Environmental Impact Statement is not necessary. A copy of the document detailing the proposal is available for public examination at the HAFB Information Repository at the Davis County Library, Central Branch, Layton UT., and also at the NEPA web page . - . . http:www.em.hill.af.milemconservationNEPAindex.htm Comments will be accepted until March 20, 2000.
