Water quality in Queensland catchments and the cotton industry
Dave Waters Cotton CRC, Qld NRME, Toowoomba 2001

Groundwater bores were sampled at Millmerran, Dalby, Chinchilla and St George every 6 months in 1998 and 1999 to determine if there was any leaching of pesticides into the groundwater system (CBWC 2001). No pesticides were detected in any of the monitored bores. An additional
bore tested on two occasions in 2001 in a cropping area close to Dalby had traces of a number of chemicals including endosulfan, metolachlor, trifluralin, atrazine, chlorpyrifos and prometryn. This is the first agriculturalbore sample in the Condamine Balonne Catchment to show a positive
detection to date.
