Continuous bioventing monitoring using a new sensor technology
- Unocal Corp., Brea, CA (United States)
Vadose zone oxygen sensors can be used effectively to improve bioventing operation and monitoring. The capabilities of the oxygen sensors for continuous oxygen measurements unattended can improve the current methods and offer alternative approaches for respiration measurements. These sensors have been used to develop a new dynamic technique of evaluating in situ respiration rates during air injection or vapor extraction which has several advantages over the traditional static oxygen uptake method. By using a subsurface oxygen sensor, the dynamic technique offers continuous monitoring capability during the bioventing process. Unlike the traditional respiration test that measures localized respiration rates, this method determines an average respiration rate in the air flow path. Because the measurements can be made at the startup of a remediation process, the operation can run without interruption. The application of this new technique and its advantages are documented in three sites.
