High Angle Remediation of Legacy Mercury Contaminated Soil at LANL - 16276
- TerranearPMC, LLC. (United States)
- Los Alamos National Security (United States)
Mercury contaminated soil was left behind by The Manhattan Project and early Cold War era operations at Los Alamos National Laboratory (LANL) in Los Alamos, NM. TerranearPMC (TPMC) was the subcontractor that successfully completed this high-angle, legacy cleanup project on a steep, difficult-to-access canyon wall in Upper Los Alamos Canyon Aggregate Area south of a busy shopping center parking lot. A Menzi Muck (spider excavator) was used in concert with a high capacity telescoping crane to remove approximately 158 cubic yards of contaminated rock and soil from the steep slope. The crane was also used to safely move personnel and equipment into and off of the site, as well as to retrieve packaged waste. All soil excavated from the site was containerised in soft-sided 1.77 cubic yard IP-1 containers and shipped to an approved, licensed, off-site disposal facility. Once excavation was completed, sampling confirmed that human health concerns and environmental risk issues had been mitigated. This proven technical approach will become the preferred method for cleaning up other similar, difficult-to access/steep legacy waste sites across the Upper Los Alamos Canyon Aggregate Area.
