Waiongana River systems. The total catchment area is approximately 6.1 km2. The length
of the catchment, from the headwaters between Paraite and Corbett Roads to the sea at Bell Block beach, is
approximately five kilometres.
The industrial area at Bell Block is situated mid-catchment (Figure 1). Historically, the industrial areas were
located predominantly on the western side of the stream however, ongoing development since 2016 has
resulted in more sites on the eastern side. These sites fall
aerobic ponds were also observed to be in
good condition. Discharge from the pond system to the Tawhiti Stream was sampled on two separate
occasions (July and March), along with the receiving waters. No visual environmental impacts downstream
of the discharge point to the Tawhiti Stream were observed.
Effluent collection points within the piggery were viewed during all inspections. They were found to be in
good condition, with no signs of spills or overflows even after heavy prolonged rain
out during fine weather following a period of heavy rain throughout the
catchment. The influent screen was operating and wastes were fully contained. The main pond was dark
green with a slightly turbid appearance. No odours were noted. Approximately 50 birds were present, the
majority of which were mallard and teal ducks.
Both wetland pond levels were normal. These were green/brown in colour and slightly turbid. The wetland
sump pump was operating at the time of inspection. No surface

The NPS-FM also anticipates that the quality of freshwater is to be improved so that it is
suitable for primary contact more often.
More detail on the swimmability targets and what these mean for Taranaki will be presented
to the Committee on the day. Basically where there are grazing animals, particularly dairy
cows, and it rains reasonably frequently causing pasture runoff, the new standards will not

million tonnes of soil.
On residential properties nearest to the Dow plant, soil dioxin concentrations were typically in the
range 5 to 15 ng/kg of soil, falling to a range of 1 to 5 ng/kg further out. One sample had a
concentration of 27 ng/kg. There was 92 ng/kg measured at a non-residential site, on the west-
facing slope of Mount Moturoa Domain.
Generally there was little difference between soil dioxin levels in lawn areas compared with
gardens on the same property.
monitoring period, issues were found with unacceptable wastes being exposed by coastal
erosion. This resulted in the site being closed to the public in 2017. Any further dune stabilisation will be
done using green waste disposed of at the Patea transfer station.
Patea Beach is an elevated site which for most of the time is dry. Rain that does fall on the site drains away
at a very rapid rate. The site does not suffer from flooding from rain or tidal action, due to its elevation.
