One year ago, on October 16, 2013, people living near the town of Cedar Valley in Curry County could not have known that a helicopter pilot and a forestry consultant would carry out an aerial herbicide application above their homes.  The pilot loaded his tanks with a concoction of 2,4D and triclopyr, two potent herbicides with a record of human health risks, and mixed them with petroleum oil.  He flew four round trips over a residential area while carrying this chemical soup.  As many as 45 residents became mysteriously ill after smelling chemicals fumes and feeling chemicals drop onto their faces.
