My projects have also included remedial action, human health and ecological risk assessments, feasibility studies, contaminant fate and transport evaluation and modeling, geologic and groundwater modeling, corrective action plans, construction/remediation cost estimates, environmental compliance, and statistical analysis. I have extensive experience conducting Phase I and Phase II Environmental Site Assessments for diverse types of sites, including municipal properties, industrial and commercial facilities, agricultural properties, timberland property packages, and oil and gas pipelines, well pads, and tank batteries. I also have experience managing brownfields projects under grant funding in Oregon and Washington.
