Abstract
Groundwater monitoring for underground storage tanks can be a complex endeavor. Each site is generally different and a site‐specific monitoring plan should be designed.
Elements or components that should be evaluated for a successful and practical underground storage tank plan for hydrocarbon detection have been identified. Some of the elements may be omitted or modified depending of the site, but the resulting plan may suffer corresponding deficiencies in hydrocarbon detection.
An effective groundwater monitoring plan should encompass several factors which should be very carefully considered and prioritized site‐specifically. Soil gas sensing coupling with groundwater sampling provide a more intelligent approach to underground storage tank monitoring for hydrocarbon contamination.
As a guiding principle, significantly more attention should be focused on the risks associated with failing to detect a plume more than any other variables or factors.
