At Florida’s southeastern tip, sweet corn (Zea Mays) is grown commercially during winter months. Most fi elds are treated with atrazine (6-chloro-N-ethyl-N’-[1-methylethyl]-1,3,5-triazine2,4-diamine). Hydrogeologic conditions indicate a potential for shallow groundwater contamination. Th is was investigated by measuring the parent compound and three degradates—DEA (6-chloro-N-[1-methylethyl]-1,3,5-triazine-2,4-diamine), DIA (6-chloro-N-ethyl)-1,3,5-triazine-2,4-diamine, and HA (6hydroxy-N-[1-methylethyl]-1,3,5-triazine-2,4-diamine)—in water samples collected beneath sweet corn plots treated annually with the herbicide. During the study, a potential mitigation measure (i.e., the use of a cover crop, Sunn Hemp [Crotalaria juncea L.], during summer fallow periods followed by chopping and turning the crop into soil before planting the next crop) was evaluated.
