The Washington State Department of Natural Resources (WDNR) is working with Evergreen StormH20 to conduct this literature review project. The goals are to gather up-to-date information about the size of particles in stormwater, bound contaminants, and the effectiveness of a range of treatment approaches for those particle sizes.
- Gather information about the different methods to measure particle size distribution (PSD) and how do they compare?
- What is more recently known about characterized sources, and nature of particle sizes and attached pollutants transported in the MS4 or delivered to BMPs?
- What is the reported effectiveness of concentration or load reduction by stormwater BMPs as a function of PSD?
This study is ongoing until November 2023.
