There has been a dramatic rise of concentrations of salt within our waterways.  Lake Champlain has seen a 30% increase over the past ten years, many local streams exceed levels that could harm Brook Trout populations and sensitive species including sugar maple.

Maintaining safe driving conditions, parking lots and walkways in addition to reducing both costs and the salting of our water bodies can be achieved through utilizing Best Management Practices including, current technology and training.

 

The WNRCD is pleased to announce our Road Salt Reduction Initiative; Through science understanding the impacts and through partnerships providing cost effective solutions. To-date the WNRCD have been awarded two grants; one for research on BMP’s to develop case-studies to document reduction strategies and another to create educational material and hold a workshop for applicators. We are working with state agencies, watershed groups, national organizations, public and private sector businesses and students to reduce the salting to our waterways.
