Massachusetts Military Reservation Environmental and Data Gap Assessment Project

4LEAF provided CH2M Hill with field staff support services for the on-going data gap investigation, environmental assessment support and treatment technology assessment at the Massachusetts Military Reservation (MMR) in Cape Cod, Massachusetts. CH2M Hill is under contract with the Air Force Center for Engineering and the Environment’s (AFCEE) MMR Installation Restoration Program (IRP). The work under CH2M HILL’s AFCEE task order focused on the Army-funded sites (CS-10 and FS-12 plumes and treatment plants) for plume and lithologic characterization efforts designed to address data gaps/uncertainties that impact assessment of groundwater remediation optimization and/or groundwater cleanup time frames, and treatment technology research, feasibility assessments, and in some cases bench testing, pilot testing or other technology demonstrations.  4LEAF prepared a site-specific Health and Safety Plan (HASP) that outlined the health and safety protocols for 4LEAF staff assigned to the project. 4LEAF’s HASP was prepared to be in accordance with CH2M Hill’s site-wide HASP.  4LEAF provided a Rig Geologist for oversight and sampling of rotary sonic drilling (sonic drilling) activities for soil borings drilled in the broad glacial outwash plain at depths of up to 400 feet. Working under the direction of CH2M Hill’s FTL, 4LEAF’s Rig Geologist was responsible for documenting and rectifying with the drillers on a daily basis on the drilling depths and quantities of materials used. All samples were collected in accordance with EPA and site-specific protocols. The Rig Geologist was also responsible for providing accurate and legible field boring logs and other field records and log books. The Rig Geologist was also responsible for providing oversight of the rotosonic rig decontamination efforts. 4LEAF also provided a Well Development Technician to provide oversight and documentation for all monitoring well completion and well development activities in accordance with the site-specific Quality Assurance Project Plan (QAPP).
