Effective cleanup at LLNL: innovative technologies and approaches

PDF Version Also Available for Download.

Description

At the Lawrence Livermore National Laboratory (LLNL) Livermore Site Superfund Site, ground water restoration efforts have been ongoing since 1989. Based on plans committed to by DOE in the Record of Decision (ROD) for the Site in 1992, ground water cleanup was predicted to take 61 years. What began as conventional pump and treat has evolved into an effective Engineered Plume Collapse strategy that employs a well-stocked tool box of remediation technologies, processes, and methodologies. This �tool box� approach has proven effective in solving the vexing problem of restoring the chlorinated volatile organic compound (CVOC) contaminated aquifers beneath the site. ... continued below

Description

At the Lawrence Livermore National Laboratory (LLNL) Livermore Site Superfund Site, ground water restoration efforts have been ongoing since 1989. Based on plans committed to by DOE in the Record of Decision (ROD) for the Site in 1992, ground water cleanup was predicted to take 61 years. What began as conventional pump and treat has evolved into an effective Engineered Plume Collapse strategy that employs a well-stocked tool box of remediation technologies, processes, and methodologies. This �tool box� approach has proven effective in solving the vexing problem of restoring the chlorinated volatile organic compound (CVOC) contaminated aquifers beneath the site. The Engineered Plume Collapse strategy has been used to hydraulically control the plumes on the western and southern boundaries of the site, doubled the pounds of CVOC removed from the subsurface compared to predictions in the ROD plans, and �collapsed� offsite plumes. The three major components of the Engineered Plume Collapse strategy are: (1) collection and use of historical and current chemical and hydrogeologic data to accurately identify areas of contamination in the subsurface and guide decisions about on-going remediation needs, (2) design, construction and operation of small, portable, and inexpensive ground water treatment units to implement pump and treat and collapse contaminant plumes back to their source areas, and (3) effective use of more energetic contaminant mass removal technologies in source areas, such as chemical oxidation, reductive dehalogenation, steam stripping, and electro-osmosis.
