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.

2.2 Results
2.2.1 Inspections
One inspection was carried out in the 2012-2013 monitoring year.
16 October 2012
A site visit was made to conduct an inspection and to take groundwater samples. The
weather was fine with 16 mm rain over the previous 72 hours. The cap on the landfill
was well vegetated and appeared sound. The level of leachate in the collection sump
was higher than usual and had approximately 3 cm of foam on it. A sample was
visit. The flow meter read 21.7 L/s, which was slightly over consent limits. The sample
taken from the discharge was only slightly turbid. Further samples were taken from upstream, downstream

and unnamed tributary sites. The downstream sample results exceeded consent limits for turbidity, however
no enforcement actions were taken at this time due to sampling methodology errors.

Results are available to the public live on our website. What we find is that water quality of the region’s bathing beaches is generally high, with around 95% of samples meeting New Zealand health guidelines for recreational use. Occasionally water quality can be affected. This is particularly evident after heavy rain when a large volume of river water is discharged to the sea, carrying contaminants such as bird faeces, sediment, urban stormwater, agricultural run-off and so on.

monitoring inspection and to take
water samples. The weather was fine with 13 mm rain falling over previous 72 hours
and the stream system was in low flow. A truck was discharging drilling muds and a
digger was operating blending in sawdust at time of inspection. A discussion was
held with the digger driver and site manager on the drainage issues at the top of the
lower irrigation area and the installation of novaflo in a few swampy areas on the
main irrigation flats. Discussion included the
freshwater and coastal swimming spots last summer found higher-than-usual levels of bacteria, reflecting the season’s higher rainfall, the Policy and Planning Committee was told. More rain meant dairy effluent ponds discharged for longer and more frequently than usual, and clouds prevented the sun from breaking down bacteria. Even so, waterfowl continued to be the main culprits at the worst freshwater sites, the Waiwhakaiho River near Lake Rotomanu and the mouths of Te Henui Stream and Waimoku Stream.
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
