Our proven experience promotes effective environmental planning, management of potential risks, and remedial investigations to minimize today's problems and tomorrow's unknowns. GSAI is one of the few firms that performs and understands remediation design form the viewpoint of the designer/builder. GSAI's professional staff has extensive experience in the design, management, evaluation, and closure of a variety of facilities including wastewater, stormwater, solid waste, hazardous waste and waste-to-energy. GSAI performs air quality studies to evaluate the impact of emissions on workers and the surrounding area; waste minimization evaluations; and environmental compliance audits. Solid waste projects have included both municipal and hazardous waste facilities, and have involved design of new facilities as well as remedial design of hazardous waste site closures.
GSAI has a solid reputation in the area of site investigation, remediation, and restoration. The relationship between the environmental staff and Garry Struthers Construction is an important factor in that reputation. GSAI has employed traditional and innovative methods for characterizing soil, as well as monitoring air, groundwater, and soil vapor.

Our firm has designed monitoring systems, collected samples using low flow purging, inline filtration, in situ samplers, and other specialized techniques. GSAI is also well versed in the statistical and multivariate analysis of groundwater data for use in conceptual site models and risk assessments.
GSAI has monitored soil vapor from air sparging/soil vapor extraction systems for several years. The need for this monitoring continues to arise with concerns about vapor transport to basements from underground storage tanks.

ESA Phase I, II
The acquisition and redevelopment of property in urban areas has given rise to the need for purchasers and sellers to conduct due diligence environmental assessments. These assessments, Phase I and II ESAs, are undertaken in order to determine if a property has been impacted environmentally by current or past activities. GSAI has conducted literally hundreds of these assessments in the Pacific Northwest, most in connection with large-scale transportation or development projects. One of the ways in which GSAI provides additional value to its clients is through an unstinting attention to detail; both in the field, and in the records review process. GSAI understands that missing a fill pipe, or failing to notice that a property appears under two names, for example, may ultimately cost its clients significantly.
The site assessment services GSAI performs are:
- Phase I ESA (ASTM E1527 00)
- Phase II ESA (ASTM 1593 97)
- Transaction Screening
