The objective of the project was to evaluate control measurements that might be made at land treatment sites to determine the effectiveness of operation in the management of hazardous wastes. Initial studies were on measurement techniques available for parameters to serve as indicators of biodegradation for a land treatment facility. An earlier paper reported results of comparative studies between wax impregnated graphite electrodes (WIGE) and platinum wire electrodes (PWE) to determine ODR and redox potential (Eh). The study indicates that WIGEs are less susceptible to oxide poisoning, easily fabricated, relatively inexpensive, and more stable in soil than PWEs. The paper reports results of using WIGEs and PWEs to measure Eh and ODR during biodegradation of glucose and phenol in a soil environment as compared to determining actual biodegradation of those compounds by analytical procedures.
