The Draft “Quality Assurance Project Plan for Urban Waters Investigation of PCBs in Soils and Stormwater Associated with Demolition Activities” is now available for review.
The objective of this study is to evaluate the potential for PCBs in building materials to impact soil and stormwater. This project involves testing soil samples prior to and following demolition activities of target properties to identify the effectiveness of current demolition practices. Stormwater will also be tested from a selected number of stormwater conveyances in the located in the study area and compared with results from previous Urban Waters studies for the purposes of trend evaluation.
The results of this study will help inform development of Best Management Practices for managing PCBs in building materials, which is Control Action 5.13 in the 2016 Comprehensive Plan to Reduce Polychlorinated Biphenyls (PCBs) in the Spokane River.
This study is being conducted by Ecology’s Urban Waters program. Because of a tight weather window and staff schedules we will be unable to make major changes to the scope of the project.
