Abstract
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 of oxygen concentration and oxygen diffusion rate (ODR) as indicators of biodegradation for a land treatment facility. The paper reports the 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.
