The City of Toronto has been a leader in enacting sustainable development in the urban environment. In 2009, Toronto passed the Green Roof Bylaw, becoming the first city in North America to require and govern the construction of green roofs on new development. The bylaw became effective January 2010 for residential, commercial, and institutional structures and April 2012 for industrial structures. To track and measure implementation, the City Planning Division needed to understand the number, size, and relative health of all vegetated roofs in the city and identify whether each roof was elective or was required by the City. In addition, Geosyntec conducted a more detailed health analysis within a smaller pilot area in downtown Toronto.

Geosyntec was retained by a major food and beverage process engineering and machinery manufacturer to undertake environmental due diligence; the global target company manufactured seed processing machinery used to produce vegetable and plant-based food-grade oils. The facility, in Kingston-Upon-Hull, Yorkshire, England, had been at the same location since 1777 and had undertaken many building projects through the centuries, the latest of which was in response to the destruction of the facility, adjacent buildings, and infrastructure during the Hull Blitz in 1941.

This manufacturing facility in Lomazzo, Italy was originally developed in the 1930s as a factory for manufacturing shoe-making tools, and was enlarged over the next several years. Beginning in the 1960s, operations at the facility consisted primarily of production of thermostats, gas valves, sensors, and timers for a number of applications. Manufacturing activities included shearing and molding of metal coils. Processes at the facility involved the use of cooling/cutting oils and perchloroethylene (PCE) as a degreaser. Manufacturing operations at the facility have since been terminated.

Chlorinated solvents in soil and groundwater beneath this former manufacturing facility are believed to have originated from a former waste solvent underground storage tank. Soils at the affected property consist of plastic clays overlying approximately 150 feet of competent shale. Limited contaminant migration has occurred through fractures in the clay soils. The client (property tenant) expedited site closure to eliminate financial obligation to property owner.
