Waltham Sanitary Sewer Overflow (SSO) Mitigation, Area 1314A:  Currently serving as Principal-in-Charge of a SSO Mitigation project for the City of Waltham, MA.  Services include flow monitoring, CCTV investigation of approximately 48,000 linear feet of sewer, and 350 manhole inspections for the purpose of providing design improvements to the sanitary sewer.

South Essex Sewerage District: Led project teams on various treatment plant upgrades, including: replacing four 8,000 gallon sodium hypochlorite tanks, upgrading oxygen reactor mixers, constructing a vac-truck unloading station, upgrading plant piping, and adding a 3’ x 8’ slide gate in the primary effluent building. Other projects involved upgrading a collection system metering station, and flow monitoring and modelling of a 78-inch interceptor sewer.

Sturbridge & Erving Wastewater Treatment Plant Upgrades: Acted as technical advisor and reviewer for upgrade of Sturbridge, MA WWTP with BioMag® and CoMag® processes.  Also served as advisor for the upgrade of Erving, MA WWTP, including new headworks, cyclic aeration system, and UV disinfection.


Agawam Water Transmission Main: Led the design and construction phase of 8,500 feet of 24-inch transmission main in Agawam, MA.  This provided a redundant water supply so that the Springfield Water and Sewer Commission, which supplies water to the Town, could replace its 54-inch steel transmission main that supplies most of the water to the Town.  The new ductile iron transmission main connection to an existing 42-inch steel transmission main involved “cutting in” two new 36-inch gate valves, a 16-inch connection to a metering vault, and pressure equalization piping around each valve.  The project also included 1,700 feet of 12-inch, and 1,400 feet of 8-inch distribution piping.

Springfield Regional Wastewater Treatment Facility: Designed 40,000 cfm regenerative thermal oxidizer to control odors from four sources at the municipal WWTP in Springfield, MA.

Wastewater Treatment Plant Odor Control Alternatives: Investigated odor control alternatives, including biofilters and chemical scrubbers, for a 15-mgd wastewater treatment plant.  Principal-in-Charge for designing a 12,000 cfm chemical scrubber system to treat odors from the facility’s biosolids thickening and dewatering operations.


Two State Agencies and Several Municipalities: Managed over 40 abatement and demolition projects that involved preparation of plans, specifications, and bidding documents for asbestos abatement and demolition of over 400 buildings.  Structures include four former state hospital campuses, several housing complexes, hospitals, power plants, incinerator, paper mill, oil terminal, textile mills, public works garage, foundries and warehouses.


Intermediate-Range Nuclear Forces (INF) Treaty Compliance: Worked as part of a multi-discipline team to assess the environmental impacts of rocket motor destruction and provide input into the Environmental Assessment that was prepared under the National Environmental Policy Act.  Traveled with the Deputy Assistant Secretary of the Army to brief the Governor of Utah, the Texas Governor’s Council on the Environment and the Assistant Director of the Colorado Department of Public Health on the environmental aspects of INF Treaty Compliance.

Various Army Installations: Planned, staffed, conducted and reported on field investigations to detect and/or define the extents of soil or groundwater contamination.  Performed field work including collection of soil and groundwater samples, evaluated analytical data and authored reports on the results.
