SUMMARY

Following aerial spraying with 2,4,5-T of 162ha of the Scrubby Creek catchment, Carboor, near Myrtleford, a monitoring program was undertaken. Water samples were taken before, during and for a six day period after spraying from Scrubby Creek and stock and domestic storages on adjacent private property, and analysed for 2,4,5-T.

2,4,5-T concentrations were below the detection limit (0.3 ug/l) in water in Scrubby Creek and in water from the storages on private property. 2,4,5-T concentrations of up to 4.2 ug/l were detected in a culvert pipe draining the main gully of the spray area. These concentrations were recorded only on the 3rd, 4th and 5th day following spraying.
