Environmental:

  • Highly Toxic to fish

  • Sub-chronic and chronic risks to terrestrial birds and mammals present a serious concern. These toxic effects may be manifested as reproductive, developmental, and hemolytic consequences.

Contamination Incidents:

  • Aug 2000: Fifteen Mile Creek near the Dalles Dam, Oregon. Truck carring 20,000 pounds crashed into bridge spilling Herbicide into creek yards from where it enters the Columbia River.
