How many different kinds of pesticides were detected in water?
About 40 pesticide compounds, of the more than 100 examined by NAWQA, accounted for most detections in water, fish, and sediment. Twenty five pesticide compounds, including 24 pesticides and 1 degradate, were each detected in more than 10 percent of water samples from streams in agricultural, urban, or mixed land-use settings, or in more than 2 percent of wells in agricultural or urban settings. Additional information about selected pesticides can be accessed in EPA fact sheets http://www.epa.gov/pesticides/factsheets/index.htm . These fact sheets provide technical information on pesticides; for example, information about newly registered pesticides and re-registration eligibility decisions made on individual organophosphate pesticides, and information on biological pesticides. The National Pesticide Information Center, a cooperative effort of EPA and Oregon State University, also has many informative fact sheets on a myriad of individual pesticides (http://npic.orst.edu/npicfact.
