Book Description
The site characterization and analysis penetrometer system (SCAPS) with laser induced fluorescence (LIF) sensors are being demonstrated as a quick field screening techniques to determine the physical and chemical characteristics of subsurface soil and contaminants at hazardous waste sites. SCAPS is a collaborative development effort of the Navy, Army, and Air Force under the Tri-Service SCAPS Program. The current SCAPS configuration is designed to quickly and cost effectively distinguish areas contaminated with petroleum products (hydrocarbons) from unaffected areas. p1+2.

Book Description
When a contaminant is treated in place on the original site it is termed in situ remediation. Bioremediation refers to cleanup effected by living organisms such as bacteria and fungi. Certain species of bacteria are able to consume pollutants as a food source, thus detoxifying these compounds. In situ bioremediation is being considered as a viable and practical solution for reducing petroleum contamination levels in groundwater.

Book Description
Air sparging is the process of injecting clean air directly into an aquifer for remediation of contaminated groundwater. For removing contaminants, air sparging relies on two basic mechanisms working either alone or in tandem: biodegradation and volatilization. The objective of air sparging is to force air through contaminated aquifer materials to provide oxygen for bioremediation and/or to strip contaminants out of the aquifer.

Book Description
Many military installations face the problem of disposing of small quantities of petroleum hydrocarbon contaminated soils. Biocells are engineered systems that use naturally occurring microbes to degrade fuels and oils into simpler, nonhazardous, and nontoxic compounds. Biocells are able to treat soils contaminated with petroleum based fuels and lubricants, including diesel, jet fuel, and lubricating and hydraulic oils. The microbes use the contaminants as a food source and thus destroy them. By carefully monitoring and controlling air and moisture levels, degradation rates can be increased and total treatment time reduced over natural systems.

Book Description
Biopile remediation is an environmental cleanup technology that uses naturally occurring microbes such as bacteria and fungi to destroy organic contaminants in soil. Certain species of bacteria are able to consume organic pollutants as a food source, thus detoxifying the pollutants. Biopile remediation is effective in treating soils contaminated with petroleum hydrocarbons such as gasoline, grease, jet fuels, diesel fuels, and motor oil. The microbes 'appetite' is enchanced by blowing air through the contaminated soil pile to provide oxygen and adding fertilizer to provide additional solid nutrients.

Book Description
Hot air vapor extration (HAVE) is a fast track, innovative environmental cleanup technolgy that uses a combination of thermal, heap pile, and vapor extraction techniques to remove and destroy hydrocarbon contamination in soil. This technology is very effective in cleaning soils contaminated with gasoline, diesel, heavy oil, and polycyclic aromatic hydrocarbons (PAH).

Book Description
Methyl tertiary butyl ether (MTBE) is a compound commonly added to petroleum fuels as an oxygenate or octane enhancer often at concentrations above 10% by volume. MTBE is currently in 70% of the gasoline used in the U.S. Due to its high water solubility, it is commonly a significant groundwater contaminant at sites affected by fuel spills. Once in the groundwater, MTBE migrates due to predominate water flow with little retardation, but may be removed by volatilization or degradation under the right conditions. A natural attenuation study is being conducted at Port Hueneme, California, to gather information on the behavior and degradation of MTBE under conditions common to fuel contaminated sites, under oxygen depleted conditions, resulting from microbial degradation of other petroleum hydrocarbons. The study site is an existing fuel hydrocarbon plume that resulted from 1984 fuel release at the Navy Exchange service station at Port Hueneme, California. The plume occurs in a shallow semi-perched water table aquifer. Constituents of concern are the compounds, benzene, toluene, ethyl benzene, and xylene (the BTEX compounds) and MTBE. A numerical model of the groundwater flow at the study site will be developed to better understand the relative importance of advection/dispersion and degradation to the migration of MTBE. Tracer tests will yield quantitative information on the fate of MTBE during migration under reducing conditions in the presence of other fuel hydrocarbons. Numerical model data will provide a means to transfer information learned at this site to other DOD and Na sites where MTBE contamination is present.

Book Description
This report summarizes the conceptualization, development and field demonstrations of the Site Characterization and Analysis Penetrometer System (SCAPS) technology from 1987 to 1999. The SCAPS provides reliable in-situ soil and groundwater testing for environmental site characterization. Probes to detect and quantify petroleum products, volatile organics, metals, explosives and radionuclides are being used by the Army and Navy, and are also available for commercial licensing.
