The water level in the firewater pond in the north western corner of the site is maintained by an abstraction from the Ngaere Stream. Overflow due to rainfall entering this pond is discharged to land and to the Ngaere Stream to the north of the pond. Stormwater from the process areas is directed to a large separator

results were available. A sample was obtained from the second skimmer pit. 2 July 2014 Inspection was conducted following a heavy rainfall event. The skimmer pits appeared clear of visual contaminants. The ring drains and bunds also appeared clear. Some combustion had been undertaken via the thermal oxidisers and no offensive smoke or odours were detected in conjunction with this. 17 July 2014 Inspection found that production was continuing on site.

addition, perched water tables are found above various impermeable layers throughout the volcanic deposits. These are caused by localised iron pans and mudstones, and have been found at almost any depth from a few metres down to about 230 m. Groundwater levels in wells drilled in volcanic deposits on the ring plain are generally close to the surface (Taylor and Evans, 1999). Recharge of the Volcanics Formation aquifers is primarily from rainfall infiltration. The Matemateaonga Formation
