Project Examples

 

Food and Beverage Distribution Facility, Northbridge, MA:

 

Provided LSP and construction support oversight services during petroleum contaminated soil removal, site dewatering, and on-site groundwater treatment as part of a warehouse building expansion project. The site construction activities included the excavation/off-site disposal of approximately 5,000 tons of impacted soil, and dewatering, treatment and discharge of approximately 1,200,000 gallons of groundwater. Responsible for facilitating routine project review meetings with applicable stakeholders to ensure that the scheduling, resourcing, and regulatory goals are being effectively communicated during the construction project.

 

 

Brownfield Redevelopment

Property,East Boston, MA:

 

Performed LSP oversight services for the removal of six abandoned fuel underground storage tanks, soil excavation and off-site management of approximately 2,000 tons of soil, and product recovery in a highly populated and sensitive area. Directed and oversaw the emergency response, investigation, risk assessment, remediation, and Massachusetts Contingency Plan compliance services. Regulatory closure was achieved within one year of release notification.

 

 

Commercial Vehicle Sales and Leasing Facility, Watertown, MA:

 

Performed LSP support services to investigate vapor intrusion concerns associated with the former manufacturing facility within a large scale commercial building. The contaminants of concern at this property were chlorinated solvents, including tetrachloroethylene and trichloroethylene. The investigation activities consisted of soil and groundwater sampling and analysis, soil gas monitoring point installations underneath the concrete slab throughout the building footprint, soil gas and indoor air screening, and soil gas and indoor air sampling.  Managed and oversaw the installation of a sub-slab depressurization system within the commercial building.

 

 

Former Industrial Manufacturing Facility, Baldwinsville, NY:

 

Directed and oversaw the completion of an ASTM Phase I Site Assessment on 34 acres of industrial land in order to determine the presence of environmental hazards with respect to the range of contaminants within the scope of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and petroleum products. Several environmental hazards associated with historic storage of oil and hazardous materials were identified at the property which lead to the performance of an ASTM Phase II Environmental Site Assessment.  

 

 

Gasoline Service Station, Nashua, NH:

 

Provided Professional Geologist/project management support services for a major oil company to assess and remediate a 10,000-gallon release of gasoline. Short term measures were implemented-multiple recovery wells, dual pump for product recovery/hydraulic containment, groundwater treatment via activated carbon, permitted effluent discharge, followed by regular monitoring and maintenance.  Soil vapor extraction and air sparging, followed by risk assessment/characterization activities brought the site to regulatory closure.

 

 

Higher Education Facility, Western Massachusetts:

 

Managed the assessment and remediation of a fuel oil release from an on-site generator system.   The removal action included the excavation and off-site disposal of approximately 100 tons of petroleum-impacted soils under an Immediate Response Action. Environmental closure achieved through the completion of a Method 3 Risk Assessment and the implementation of an Activity and Use Limitation (AUL) on the property to control future site conditions and limit future exposures to site soils.

 

 

Residential Neighborhood, Ashburnham, MA:  

 

Lead investigator/field director for the assessment and remediation of a complex and large scale contaminant plume originating from a gasoline service station in an environmentally sensitive area. Response actmentions associated with this gasoline release expand over 1,500 feet and the receptors of concern include private supply wells, surface water/wetlands, and residential basements. Given the large scale contaminant plume geometry, several residential private supply wells required point of entry remedial systems to mitigate critical exposure pathways. Responsible for organizing public involvement meetings for miscellaneous 3rd party property owners/ stakeholders, local municipalities and regulators.
