FREE PRODUCT RECOVERY AT AN INDUSTRIAL SITE
Active free product recovery pumps were installed in 2007, but failed to materially change the free product thicknesses observed at target monitoring wells. Recently, BUSTR informed our client that the site was not showing satisfactory progress and that additional measures were necessary. The preponderance of data available regarding the site which includes dozens of monitoring wells and soil borings as well as over a decade worth of fluid level measurements provides a unique opportunity to retroactively assess our approach to the site. This presentation aims to provide a critique our efforts. It will also serve as a guide for future LNAPL projects. The lessons learned at the site can help evaluate remedial approaches at future LNAPL sites.
