Tad Deshler's 28 years of environmental consulting experience focuses on in-water sites and the interface between in-water sites and adjacent upland environments, where understanding the pollution transport mechanisms that connect the environments is paramount. He has worked extensively with environmental attorneys in both compliance and allocation contexts. He is effective at both the strategy and policy levels, due to his deep understanding of quantitative environmental science, and the legal and regulatory systems.
Prior to forming Coho Environmental, Tad was one of the founders of Windward Environmental. He focused on Superfund site sediment assessment and risk assessments, including the Lower Duwamish Waterway (Seattle, WA), Portland Harbor (Portland, OR), and the Lower Passaic River (NJ). He managed the information management group, where he used his data analysis expertise to evaluate spatial relationships and mine the rich datasets typically associated with Superfund sediment sites.
Earlier in his career, Tad conducted hazardous waste site reviews all over the United States for NOAA, giving him a valuable perspective on the preferred technical approach utilized by this natural resource trustee. He also conducted modeling of the fate and effects of dredged material disposal. Tad prepared several Ocean Discharge Criteria Evaluation (ODCE) reports in support of general NPDES permits, including oil and gas exploration in the Beaufort and Chukchi Seas (AK), log transfer facilities in Alaska, and salmon net pen operations in Puget Sound. He also participated in multi-year bioassessments in the Columbia (WA-OR) and Willamette (OR) Rivers, including evaluating sediment and water quality, and impacts to fish communities.
Mr. Deshler holds a BA degree in Aquatic Biology from the University of California at Santa Barbara and an MS degree in Animal Science from the University of California at Davis.
