the area and reduce ponding. The culvert over the waterway looked good and
appeared to be coping with flood events. The area where muds were originally spread
had pasture establishing. The area where muds were most recently being applied had
good contouring and bunding across three sides. Some muds had migrated to the soil
surface through natural processes; these muds were found to be weathering and broke
apart easily when handled. Ponded water around the spreading area from recent rain

dissipated within 25 m. There were no visible emissions to air. An odour survey was conducted around the

There was light rain falling during the inspection, however only 3 mm of rainfall had been recorded over the
previous week at the Brooklands Zoo monitoring station. Stormwater pond SV8000 contained 800 m3 of

Results and Discussion
On the day that the nets were set, a localised rain event caused flows to increase in the Haehanga Stream.
This also resulted in the discharge of sediment-contaminated stormwater into the Haehanga Stream,
resulting in discolouration. Although discolouration is frequently noted in this catchment, the degree of
discolouration at sites 2 and 3 was

any waters emerging from the cliff would be swiftly mixed and dispersed. Any effects on groundwater
quality or coastal water quality would be negligible. In general the creation of stable interlocked layers of
green waste ensures that it does not fall off or get blown off the cliffs and down onto the coastal marine
area or into the sea.
The effect of the sand movement from the lack of dune systems has seen the degradation in the land

appeared that the skimmer pit had recently
discharged, considering the volume of rain that had recently fallen it was likely that the skimmer pit still had
a leak. No effects were noted in the receiving waters downstream of the discharge point.
