Her professional practice focuses on site assessment of groundwater, soil, and soil vapor conditions; engineering design for remediation systems; environmental permitting for remediation projects; construction, construction management, and quality assurance of remediation systems; remediation system operations and maintenance issues; and expert consultation in support of litigation.
