The herbicide atrazine is used for control of broadleaf weeds, principally in corn, sorghum, and sugarcane . Atrazine is currently used in 70 countries at an estimated annual rate of 111,000 tons [2, 3]. Atrazine is typically applied early in the planting season. However, Heavy rainfall events, shortly after application may lead to detectable atrazine concentrations in waterways and in drinking-water supplies. The United States Environmental Protection Agency established a 3 ppb limit of atrazine in drinking water. In some instances, municipal water treatment plants use chemicals and other treatment processes, such as activated carbon, to reduce atrazine to below the 3 ppb legal limit for drinking water.
