Agricultural impacts on groundwater : research on Prince Edward Island / M.W. Priddle and R.E. Jackson. : En13-5/89-115E-PDF
"Groundwater quality has been monitored from 1985-1988 beneath three potato fields on Prince Edward Island to which aldicarb (Temik) and nitrogen fertilizers had been applied. Aldicarb residues in the sandstone aquifer were detected more than five years after the last application. Persistence of aldicarb appears related to its application at planting rather than at plant emergence. The oxidation of ammonia fertilizers may also create conditions conducive to persistence. It is likely that both aldicarb and nitrogen residues are stored in the unsaturated zone and flushed to the water table during periods of high recharge (i.e., Spring). This study has shown the need for research prior to pesticide registration to determine impacts on groundwater"--Abstract.
