Pesticides play an important role in agriculture.
They have increased farm production, and they have enabled farmers to manage more acres with less labor. If pesticides are not handled carefully around the farmstead, they can seep through the ground after a leak or spill, or they can enter a well directly during mixing and loading. Taking voluntary action to prevent pesticide contamination of groundwater will help assure their continued availability for responsible use by farmers. Pesticides work by interfering with the life processes of plants and insects. Pesticides are also toxic to people.
