How does EPA ensure the safest possible use of pesticides?
EPA must evaluate and register pesticides before they may be sold, distributed, or used in the United States. The Agency is also in the process of reassessing, and reregistering when appropriate, all older pesticides (those registered prior to 1984) to ensure that they meet current scientific standards. To evaluate a pesticide for either registration or reregistration, EPA assesses a wide variety of potential human health and environmental effects associated with use of the product. The producer of the pesticide must provide data from tests done according to EPA guidelines. These tests determine whether a pesticide has the potential to cause adverse effects on humans, wildlife, fish, and plants, including endangered species and nontarget organisms. Other tests help to assess the risks of contaminating surface water or ground water from leaching, runoff, or spray drift. If a pesticide meets EPA requirements, the pesticide is restricted for use in accordance with label directions. Howeve
