SCI-GROW Model for Groundwater Risk Assessment of Pesticides

The SCI-GROW model,developed by USEPA and commonly used in the United States,was selected to predict risks to groundwater of five types of pesticides frequently used in sugarcane fields in Fujian Province.Comparison between prediction and field measurement was carried out to validate the model.Results show that good correlation was observed between the two.The SCI-GROW model was applicable to screening assessment of groundwater contamination risks of pesticides in areas where groundwater is vulnerable to pesticide contamination in the coastal region of Southeast China with characteristics of higher in groundwater table,substantial in rainfall,and sandy in soil texture.In the end,the SCI-GROW model was used to predict risks of seventeen types of pesticides commonly used in the country,with a view to providing scientific reference for use of these pesticides.
