Atrazine was amended into an agricultural drainage ditch and constructed wetlands for the purpose of monitoring transport and fate of the pesticide. Aqueous half lives of 6 and 16 to 48 days in drainage ditch and constructed wetlands, respectively, were found. Flow paths of 50 m and 103 to 281 m were required to mitigate atrazine in the drainage ditch and constructed wetlands, repectively. This information provided design parameters for ditches and constructed wetlands to mitigate the herbicide in agricultural runoff.(Download PDF) (Export to EndNotes)
