Frduration7are <br /> g chart summarizes the Environmental Fate Data for the name and type of <br /> l applied, and the soil, groundwater and surface water persistence. Noted times of <br /> maximum values observed. The FateData is highly specific for various <br /> al conditions, and is normally expressed in half-lives. <br /> PESTICIDE TYPE SOIL WATER <br /> POSSIBLY APPLIED PERSISTENCE PERSISTENCE <br /> TO THE PROPERTY <br /> Chloropicrin Soil Fumigant 8 - 24 hrs, 4.5 days 31 hours <br /> Guthion Insecticide 5 days 2 days <br /> Methyl Bromide Biocide 30 - 60 days 6.6 hours <br /> Paraquat Herbicide 1000 days 13.1 hours <br /> Supracide Insecticide 5 - 23 days Unknown <br /> Dimilin Insecticide 3 - 4 days 72 hours <br /> Asana Pyrethroid Insecticide 15 - 90 days 21 days <br /> Lorsban Insecticide 11 - 141 days 3.5 - 20 days <br /> Dimilin Insecticide 3 -4 days 1 -3 weeks <br /> Methomyl Insecticide 14 days 25 weeks <br /> Parathion Insecticide 49 days 1 - 10 days <br /> Strychnine Rodenticide Unavailable Unavailable <br /> The predominate wind direction through the area is east-southeast. Due to the increase in <br /> development to the west-northwest, and the fact that there will be housing development <br /> surrounding the subject property,there is no agricultural production land in proximity to the site <br /> in the west-northwest direction (upgradient to wind direction). Row crop production is to the <br /> south of the property. The predominate wind direction, along with the fact that agrichemicals <br /> cannot be applied during windy conditions, ensure that the likelihood of impact to the property <br /> from pesticide drift is highly unlikely. <br /> VI.
