Compound Specific Isotope Analysis (50 minutes)
Compound Specific Isotope Analysis (CSIA) is a powerful new technique which has been developed to evaluate the state and progress of in-situ degradation processes at field scale. In many cases, (e.g. benzene, MTBE, TBA, DCE) CSIA may provide the only definitive proof that a contaminant is degrading in-situ. Additionally, evaluation of this data can provide a conservative estimate of the fraction of the component degraded, the mechanism of degradation, and the in-situ rate of degradation. While the study of isotopes is not new, the ability to determine isotope ratios in continuous flow mode has only recently been developed to be useful at concentrations of interest in environmental studies. This presentation will briefly discuss the analytical technology and the fundamentals of stable isotopes so that we may understand its application to in-situ processes. We will use these concepts to illustrate the use of CSIA in evaluating in-situ degradation of the fuel oxygenates MTBE, TBA, and the chlorinated solvents such as PCE and its daughter products. Finally we will discuss how the use of isotopic constraints in groundwater transport modeling may significantly improve our ability to predict the development of plumes. Compound Specific Isotope Analysis (25 minutes)
A less technical discussion of the Techniques and Applications of CSIA with respect to hydrocarbons, chlorinated hydrocarbons and fuel oxygenates. Monitored Natural Attenuation (50 Minutes)"Monitored Natural Attenuation Basics for Hydrocarbons, Chlorinated Hydrocarbons and Fuel Oxygenates" Natural attenuation processes should be evaluated when preparing a remedial action plan for a site with petroleum or chlorinated solvent contaminated soils and groundwater. While natural attenuation processes include biodegradation, abiotic degradation, sorption, dispersion, and volatilization, numerous studies have indicated that the natural, in-situ biodegradation process is the primary mechanism for the attenuation of petroleum hydrocarbons and chlorinated solvents in the subsurface. Biodegradation is a natural attenuation mechanism that has the potential to destroy the contaminants in-situ with nontoxic inorganic end products. As we understand the natural process, we are learning how to enhance and accelerate it. An approach for evaluation of intrinsic bioremediation processes focused on evaluation of terminal electron acceptors in the groundwater for both petroleum hydrocarbons and chlorinated solvents will be presented. Microseeps has recently announced the development of low level volatile fatty acid (LLVFA) analysis which is a key to understanding the process of stimulation of biodegradation of chlorinated solvent and other contaminant plumes. Abiotic degradation processes have also been recognized to be of significance in some chlorinated solvent plumes. The degradation pathway for this process is significantly different from the more familiar biological degradation pathway and requires unique analytical parameters to confirm. The state of understanding of this process will be discussed. The current state of understanding of natural and enhanced attenuation of MTBE in groundwater will also be discussed, including a brief discussion of the use of Stable Isotopes of carbon and hydrogen in evaluation of degradation progress. Microseeps Services (30 minutes)A discussion of Microseeps analytical services, in particular the niche analytical services and their application and use with respect to in-situ degradation will be presented. Services to be discussed include:
Dissolved Gas Sampling (20 minutes)Microseeps’ sampling services in support of intrinsic and enhanced in-situ degradation will be discussed. In particular, the use of the bubble strip sampler for dissolved hydrogen will be discussed. This sampler eliminates several problems associated with sampling for dissolved hydrogen, the master variable for assessing groundwater redox processes.
