The specific objectives of the field study are: 1. To demonstrate whether the pro- posed method of promoting the enzymatic decomposition of TCE and related compounds is effective under controlled experiments per- formed in-situ, in an aquifer representing conditions typical of ground water environments; 2.

Careful site characterization and implementation of quantitative monitoring methods are prerequisites for a convincing evaluation of enhanced biostimulation for aquifer restoration.

This paper describes the characterization of a site at Moffett Naval Air Station, Mountain View, California, and the implementation of a data acquisition system suitable for real-time monitoring of subsequent.

He is a Science and Engineering Associate in the Department of Civil Engineering at Stanford University. He has participated in several field investigations related to contaminant transport and enhanced methods for aquifer restoration.

He has developed and operated the automated data acquisition and control system used in this field by: A Field Evaluation of In‐Situ Biodegradation of Chlorinated Ethenes: Part 3, Studies of Competitive Inhibition Lewis Semprini Department of Civil Engineering, Stanford University, Stanford, California Cited by: A field study of biodegradation of trichloroethylene (TCE) through methane injection was conducted at the yard of a home in Japan.

Methane was selected as the safest substrate for injection into groundwater. Methane, oxygen, nitrate, and phosphate were introduced into groundwater contaminated with μg/L of by: Careful site characterization and implementation of quantitative monitoring methods are prerequisites for a convincing evaluation of enhanced biostimulation for aquifer restoration.

In situ groundwater bioremediation of hydrocarbons has been used for more than 40 years. Most strategies involve biostimulation; however, recently bioaugmentation have been used for dehalorespiration.

Aquifer and contaminant profiles are critical to determining the feasibility and strategy for in situ groundwater : Terry C Hazen. Restoring these aquifers and minimizing human exposure to the parent chemicals and their degradation products will require the identification of suitable biomarkers of human exposure; better understandings of how exposure can be related to disease outcome; better understandings of mechanisms of transport of pollutants in the heterogeneous structures of the subsurface; and field testing and evaluation of Cited by: Documenl No.

Environmarntal Protection Agency -Region VI and the Texas Water CommBs~ion. limitations inherent in evaluating in situ bioremediation Because the subsurface is complex and incompletely accessible, knowledge of the fate of ground water contaminants always will be limited.

This situation is intensified for in situ remediation technologies of any type, because frequently the amount, location, and type of contamination are unknown. Microbial Biodegradation and Bioremediation brings together experts in relevant fields to describe the successful application of microbes and their derivatives for bioremediation of potentially toxic and relatively novel compounds.
