Abstract A pilot scale demonstration of nutrient injection to stimulate in situ bioremediation of chlorinated solvents was performed at the Pinellas Science, Technology and Research (STAR) Center, formerly the U.S. Department of Energy Pinellas Plant in Largo, Florida. This project was implemented (January through June, 1997) for the Innovative Treatment Remediation Demonstration (ITRD) program to evaluate reductive anaerobic biological in situ treatment technologies (RABITT) as an innovative remedy. Based on laboratory studies and additional site characterizations, a vertical flow system with two horizontal wells and a series of infiltration galleries was constructed, allowing development of an effective ground water recirculation pattern to enable continuous nutrient (benzoate, lactate, and methanol) addition and enhance system performance. The performance of this system was closely monitored by tracking ground water flow rates, measuring hyraulic head changes in the aquifer, analyzing flow paths and biotransformation pathways. A three dimensional aquifer monitoring network was used to measure nutrient movement and associated contaminant degradation. Extracted ground water was also continuously monitoring for contaminants before recirculation. Significant dechlorination was observed in areas where nutrients were effectively delivered. Evaluation of the results suggests the process is applicable and cost effective with apropriate implementation, and site characterization.
