PRACTICAL GROUNDWATER MONITORING FOR UNDERGROUND-STORAGE TANKS

Groundwater monitoring for underground storage tanks can be a complex endeavor. Each site is generally different and a site-specific monitor ing plan should be designed. Elements or components that should be eva luated for a successful and practical underground storage tank plan fo r 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 eff ective groundwater monitoring plan should encompass several factors wh ich should be very carefully considered and prioritized site-specifica lly, Soil gas sensing coupling with groundwater sampling provide a mor e intelligent approach to underground storage lank monitoring for hydr ocarbon contamination. As a guiding principle, significantly more atte ntion should be focused on the risks associated with failing to detect a plume more than any other variables or factors.
