Envirocon recently began work on the City of Boulder, 13th Street Manufactured Gas Plant (MGP) Remediation project in Boulder, CO. The scope of work includes removal of approximately 12,000 tons of impacted materials, including the MGP infrastructure, soil, fluids and debris. Monitoring wells on site detected the presence of benzene and naphthalene, common byproducts of coal gasification which occurred on the site from 1902 to 1952. Contaminated soils are excavated under a temporary enclosure to control any fugitive vapor and odor emissions. A ventilation system filters the air before it is released. The project is scheduled to be complete in March.
