Superfund Record of Decision (EPA region 8): Marshall Landfill Site, Boulder County, Colorado, September 1986. Final report

Technical Report · Fri Sep 26 04:00:00 EDT 1986

OSTI ID:6076305

The Marshall Landfill accepted unstabilized sewage sludge and many unidentified and potentially hazardous wastes. Septic wastes and liquid industrial wastes were also disposed offsite in two, now closed, septic ponds. The primary contaminants of concern include: VOCs including TCE, PCE, DCE, and benzene, and heavy metals including cadmium and lead. The selected remedial action includes: installation of a subsurface collection system using natural ground water gradients to collect all contaminated ground water leaving the Marshall Landfill site; treatment of contaminated ground water by sedimentation, air stripping, and off-gas carbon adsorption; landfill improvements, including regrading, revegetation, perimeter ditches, and fences, to minimize future environmental and public health impacts from the site, and ground and surface water monitoring.
