We have performed more than 1,900 projects, ranging from small projects of short duration to large investigations that span several years. The complexity and magnitude of our projects have ranged from complete property redevelopment (i.e., planning, demolition, environmental characterization, hazard evaluation, remedial analysis, public participation, remediation, solid and hazardous waste management, environmental oversight of site construction) to the assessment of mold at a private residence.
