Biopiles for Site Remediation
Credit: 2 PDH
Subject Matter Expert: Mark Knarr, P.E., CEM, LEED AP BD+C, PMP, CCEA, GPCP
In Biopiles for Site Remediation, you'll learn ...
- How biopiles can be used to reduce concentrations of petroleum constituents in excavated soils
- The advantages, disadvantages and limitations of biopiles
- Evaluation of biopile effectiveness based on soil and constituent characteristics
- How climactic conditions affect the design of biopiles
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, biopiles can reduce concentrations of petroleum constituents in excavated soils through biodegradation. This technology involves heaping contaminated soils into piles and stimulating aerobic microbial activity within the soils through the aeration and/or addition of minerals, nutrients, and moisture. The enhanced microbial activity results in degradation of adsorbed petroleum-product constituents through microbial respiration. Biopiles are aerated most often by forcing air to move by injection or extraction through slotted or perforated piping placed throughout the pile.
This course is intended for environmental engineers who wish to expand their knowledge of alternative methods of site remediation.
