The State Nutrient Reductions Strategies Web series has merged with the Nonpoint Source (NPS) Technical Exchange forum to cover a broader variety of NPS topics.

We are currently working with our partners on new topics and new methods of engaging in discussion on current nonpoint source technical topics of interest. Stay tuned for future announcements.  In the interim, you can view PDFs of the PowerPoint presentations from some of our past webinars below.
