Reducing Trash In Our Waterways; Regulatory Challenges & Trash Control BMP's

Trash conveyed in runoff on land can have major environmental and economic impacts on states and communities throughout the U.S. 80% or more of trash conveyed in runoff comes from land-based sources.

A recent study estimated that without greater mitigation efforts to stop trash loadings into waterways, the world’s oceans will contain nearly 250 million metric tons of plastic by 2025, or approximately one pound of plastic for every three pounds of fish.

Reducing trash in waterways is a problem that can be solved with the collective effort of the public, Federal, State and Local agencies, NGOs and municipalities.  

The goal of this Webinar is to share insights and knowledge on State and local efforts to control the discharge of trash into local waterways as well as provide examples of effective trash reduction practices and devices that prevent trash from entering local streams, rivers and oceans.
