Bob Anderson, Christian Nilsen and Myles Gray to Present at Managing Stormwater at Managing Stormwater in Washington

Robert Anderson, LHG, CWRE (Washington), Christian Nilsen, P.E. (Washington), and Myles Gray (Oregon) will be presenting at the Managing Stormwater in Washington at the Greater Tacoma Convention Center in Tacoma, Washington on March 11, 2020.

Additionally, Rich Wildman, Ph.D. (Oregon) will be moderating a session in Track B entitled "Industrial."

Bob Anderson is a Senior Principal Hydrogeologist with more than 30 years of experience focused on water resources development and management for clients in the western United States.

Christian Nilsen is a Senior Water Resources Engineer based in Washington with more than 10 years of experience focused on stream and wetland restoration, stormwater management, and water quality.

Myles Gray is an Engineer based in Oregon focused on stormwater treatment, hydrology, and green infrastructure research and monitoring.

Rich Wildman is a Scientist based in Oregon with more than 15 years of experience focused on water quality, trace element biogeochemistry, lake and reservoir hydrodynamics, and data analysis.

This focused one-day conference is Washington's leading stormwater event, convening regulated companies, governments, solution providers, and regulators for learning, networking, and business development. In addition, Managing Stormwater in Washington features the region's largest stormwater trade show with over 40 service and technology solution providers.

Northwest Environmental Business Council (NEBC) is a non-profit trade association that represents the interests of its members, while promoting the health of the industry and the environment as a whole. Formed as a regional organization in 1996, NEBC is the recognized voice of the industry – advocating for science-based regulation, supportive policies and tax structures, the dissemination of knowledge, and the adoption of best practices.

Geosyntec Participation

Title: Stormwater and PFAS
Presenters: Bob Anderson, Geosyntec Consultants, Inc., Frances Bothfeld, Washington State Department of Ecology, Jack Spadaro, Wood PLC
Track: D Science and Research
Description: Per- and polyfluoroalkyl substances (PFAS) have been an emerging contaminant of concern to groundwater and surface water, especially with respect to potential exposure through drinking water. With increasing knowledge of the sources of PFAS and its persistence in the environment, there is expectation that there will be emerging needs to deal with PFAS in stormwater runoff as well. Speakers will discuss PFAS sources, a background on the many different chemical forms of PFAS, its fate and transport in the environment, site case studies, treatment approaches, and Department of Ecology's evaluation of this issue.

Title: Climate Change and Stormwater
Presenters: Jeff Burkey, King County, Guillaume Mauger, University of Washington, Christian Nilsen, Geosyntec Consultants, Inc., James Robertson, The Nature Conservancy
Track: C Municipal & Development
Description: How will climate change impact the Pacific Northwest? For stormwater impacts, heavy rainfall events are projected to become more intense over time. With help from the UW Climate Impacts Group, local jurisdictions and stormwater professionals are assessing the impact of urban and rural runoff, stream response and BMP performance under different climate scenarios and the projected increase in heavy precipitation.

Title: Effective Treatment of Persistent Organic Pollutants in Stormwater Runoff
Presenters: Myles Gray, Geosyntec Consultants, Inc., Richard Jack, King County, Chelsea Mitchell, Washington State University
Track: B Industrial
Moderator: Rich Wildman, Geosyntec Consultants, Inc.
Description: Growing evidence suggests that persistent organic pollutants, like PCBs and PAHs, can be found in stormwater runoff from all types of land uses across Washington. Because these pollutants persist in rivers, lakes, and marine waterbodies, they can create long-term impacts, affecting human health and aquatic species. These types of pollutants can persist up the food chain, leading to high levels in top predators such as the Southern Resident Killer Whale population. This session will highlight three recent studies that have investigated the effectiveness of bioretention Best Management Practices to remove persistent organic pollutants from stormwater runoff. Results from these studies suggest that bioretention BMPs can effectively remove persistent organic pollutants from stormwater runoff. Presentations will highlight bioretention design parameters that can improve removal of persistent organic pollutants from runoff, including bioretention soil media selection and design treatment flow rates.
