The S-Road Facility Landfill provides a state-of-the-art, lined and environmentally secure, non-hazardous solid waste disposal site located within the eroded hills of Mancos Shale about 8.5 miles northwest of Mack CO, at the northwestern extent of the Lower Grand Valley in Mesa County.
The new ownership group of S-Road Facility Landfill has invested heavily in improving all aspects of the landfill, including recently installing a high-tech, Geosynthetic Clay Liner system (GCL) in a new disposal cell, which overlies the more than 1,500 feet of low-permeability, naturally occurring Mancos Shale formation.
The first groundwater aquifer below the site is the Entrada Sandstone Aquifer, which is about 2,000 feet below the ground surface, and is a high salt content (saline, or brackish) water.
This high desert area has an annual precipitation of less than 6.5 inches per year. This causes S-Road Facility to be an ideal site for non-hazardous waste disposal.
The US Department of Energy, after extensive investigation, chose a similar site near Crescent Junction, Utah, about 50 airmiles to the west of our S-Road Facility Landfill, as the preferred land disposal site for the redisposal of the large volume of uranium mill tailings from the former uranium ore processing facility near Moab, Utah. That site relies only on the favorable, natural geology (Mancos Shale) without any engineered liner. Thus, the S-Road site exceeds even the DOE site’s environmental security.
