Fate and Transport of Fuel Components Below Slightly Leaking Underground Storage Tanks

摘要: Abstract Fuel leaks from underground storage tanks (USTs) and piping have been a major source of groundwater contamination. In the U.S. Europe, regulations requiring upgrading USTs to meet specific standards significantly reduced instances fuel Leak detection is primarily dependent on physical measurement systems that are generally capable detecting leak rates as small 0.2 L/h. smaller than this threshold may remain undetected for long periods time, posing risk contamination shallow resources in sensitive areas. This was evaluated by modeling fate transport components UST under variety subsurface conditions assuming secondary containment does not exist. It found do potential impact groundwater, particularly if conducive natural attenuation processes. explain situations where has below service stations virgin areas upgraded systems. Modeling indicates passive venting tank backfill could virtually eliminate volatile resulting leaks.
