Stream, were due principally to resident wild fowl populations in the vicinity of
recreational usage sites (as confirmed by inspections and more recently by DNA marker
surveys).
In terms of E. coli, bacteriological water quality in the latest survey period was similar in
comparison with historical surveys. The total number of samples falling within the “Alert”
or “Action” categories (28% of samples) was equal to the long-term average and was
strongly influenced by samples at two urban sites

reflect that rainfall at the coast is richer in chloride and
sodium, compared to rainfall that falls inland. Nearly two thirds of GQMP sites plot
below the SWDL, suggesting that much of the region’s groundwater is enriched with
sodium from rock/water interactions with sodium rich source rocks.

has been little change in groundwater nitrate levels over the last five years. There is

Rainfall
Annual rainfall varies throughout the region. Some coastal areas receive less than 1,400 mm annually, while
the summit of Mount Taranaki receives around 7,500 mm.
Heavy rainfall events do occur and there can be extremes. In 2012 heavy rain caused a number of slips on
the coastal road around Mount Taranaki, including a large slip at Oākura that covered the road, burying a

Inspection was conducted in conjunction with groundwater sampling:-
• No material had been stored or spread via this site for some years.
• The old cells and stormwater ponds were full of rain water.
• No sheen was evident, but some odour was observed immediately downwind
of the cells during groundwater sampling.
• No other issues were noted.
was no sign of recent overflow discharges into the Kurapete Stream. The WWTP and facilities were
operating satisfactorily, with the pond perimeter tracks recently mown. No odours were noted onsite.

An inspection was conducted in fine weather with light wind. Rainfall of 276 mm of rain was recorded at the
Inglewood WWTP Council weather station in the month prior.
The primary screen was operating and wastes were fully contained. The primary aeration pond was a turbid

The monitoring indicated that the operation of the sluicing of the weir has improved, with flows not falling
below 151 L/s. There was one unauthorised incident recording non-compliance in respect to the water take
consent between 30 July and 5 August 2022. Due to a lightning strike which destroyed the scheme’s
electronics, OWSL were required to take water in manual operation mode, which resulted in a breach of
abstraction rate until OWSL could fine-tune the process. The
