EPA confirmed nearly 3,000 new releases from underground storage tanks (USTs) during fiscal year 2010, bringing the cumulative total to 491,572 releases since 1984. Although progress has been made in cleaning these sites, over 96,000 of them still require remedial action. These UST leaks pose a grave threat to human health and the environment by contaminating groundwater and soil.
As an alternative to traditional pump-and-treat or soil excavation, soil vapor extraction (SVE), also known as soil venting or vacuum extraction, is an in-situ technology that reduces concentrations of volatile constituents in petroleum products adsorbed to soils in the vadose zone. With SVE, a vacuum creates a negative pressure gradient in the soil matrix that moves hydrocarbon vapors toward extraction wells; these wells in turn remove the vapors from the soil. However, one must carefully consider both the site conditions and contaminant properties before implementing SVE.
This course is intended for environmental engineers who wish to expand their knowledge of alternative methods of site remediation.
Specific Knowledge or Skill Obtained
This course teaches the following specific knowledge and skills:
- Initial and detailed evaluation to determine viability of SVE
- Influence of soil and contaminant properties on SVE performance
- SVE system design and components
- Methods for computing quantity of extraction wells
- Vertical vs. horizontal extraction wells
- Phases of SVE operation: start-up and long-term
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. PDH credits are not awarded until the course is completed and quiz is passed.
