Biography

Patrick Hsieh, Senior Chemical Engineer, Remediation and Environmental Compliance BS and MS in Chemical Engineering from University of Rochester, NY Over 20 years’ experience in site investigation, remediation, and environmental compliance with a focus on sites in the Pacific Northwest. Mr. Hsieh’s experience includes the design, implementation, and O&M of a variety of remedial technologies at both marine and upland environments with complex remediation challenges. Specialties include in-situ remediation, TSD Operations and Compliance, and water treatment (wastewater, stormwater, dredge return water). Mr. Hsieh has volunteered time with the Interstate Regulatory Council (ITRC) to assist in providing guidance on environmental issues including: Stormwater Treatment BMPs, PFAS, 1,4-Dioxane, and Sediment Cap Design.
