Abstract: Public concerns about stage 1 of the joint Department of Conservation/Taranaki Regional Council
possum control operation on Mount Taranaki/Egmont included issues relating to potential effects of the use
of 1080 poison on water quality and water usage, in particular domestic water supplies from catchments
drainign areas within the aerial poison application zone. Taranaki Regional Council undertook a
comprehensive water quality moniotring programme in recognition of these concerns, despite the existence
of documented water quality monitoring information for two earlier aerila control operations (Waipoua
Forest and Rangitoto Island) which indicated that no contamination of natural water by 1080 resulted from
these large scale operations. This programme included natural surface waters within and outside (controls)
the operational zone, major water supplies (raw and treated) and groundwaters. Monitoring concentrated on
1080 and fluoride (the principal breakdown product) concentrations in the waters. Sampling commenced in
advance of the first aerial application of 1080 and extended througout the operational period with one site
smapled more intensively to monitor any immeduate impacts of the department of Conservation's initial
three-day aerial poison drop within the National Park. In addition to the physicochemical monitoring, the
programme was augmented with biological monitoring of three representative catchment sites draining the
opertaional area and two catchment sites (controls) immediately beyond the boundaries. The results
consistently showed no measurable impact of the possum control operation on the physicochemical
parameters (1080 and fluoride concentrations) or biological indicators (benthic macroinvertebrate fauna)
measured in any of the natural waters draining botht he National Park and the buffer zones within the
operational poisoning area. No impacts attributable to the possum control operation were measured on
these physicochemical parameters in teh raw and traeted domestic water supplies, or groundwaters
monitored. The resutls of this relatively intensive monitoringprogram may provide guidelines for the
assessment and estbalishment of appropriate monitoring of any future possum control operations of this
nature.

Abstract: Public concerns relating to the joint Department of Conservation/Taranaki Regional Council
possum control operation on Mount Taranaki/Egmont included issues relating to potential effects of the use
of 1080 poison on water quality and water usage, in particular domestic water supplies from catchments
draining areas within the aerial poison application zone. Taranaki Regional Council, in 1993, undertook a
comprehensive water quality monitoring of stage 1 of the control programme in recognition of these
concerns, despite the existence of documented water quality monitoring information for two earlier aerila
control operations (Waipoua Forest and Rangitoto Island) which indicated that no contamination of natural
water by 1080 resulted from these large scale operations. Taranaki Regional Council results consistently
showed no measurable impact of the possum control operation on the physicochemical parameters (1080
and fluoride concentrations) or biological indicators (benthic macroinvertebrate fauna) measured in any of
the natural waters draining both the National Park and the buffer zones within the operational poisoning
area. No impacts attributable to the possum control operation were measured on these physicochemical
parameters in the raw and treated domestic water supplies, or groundwaters monitored. The results of this
relatively intensive monitoring programme provided guidelines for the performance of an appropraite
monitoring programme in association with the remaining stages (2&3) of the Mount Taranaki/Egmont
possum control operations. The programme concentrated on the physicochemical moniotring of seven
treated local authority water supplies abstracted from catchments draining the operational area, and was
complemented with intensive monitoring of one raw surface water supply catchment, and biological
monitoring of representative surface waters in close porximity to the National Park operational area.
