Cleaner Water from No-Spray Buffer Zones
A look at recent modeling that shows how no-spray buffers reduce pesticide contamination along waterways.
By Aimee Code
The National Marine Fisheries Service (NMFS) recently evaluated the 300 foot no-spray buffer zones that NCAP and allies won as interim protective measures in 2004. Not surprisingly, NMFS found that these buffer zones are providing a substantial benefit to salmon that would otherwise be subject to heavy pesticide exposure.
Using drift estimations based on aerial diuron sprays, the NMFS model compares surface water that is protected by the 300 foot buffers to surface water that isn’t protected. The outcome is dramatic: pesticide levels were almost one hundred times less with the buffer zones.
In all, the NMFS report evaluated the risks that six pesticides pose to Pacific salmon and steelhead. Be sure to check out the full report (PDF download) to get all the details.
NCAP will provide further comments as we wade through this 1000 page tome. We appreciate your support as we continue the fight for accurate science and policies that protect endangered wildlife rather than pesticide industry profits.
