consent also states that the irrigation of pond fluids shall not cause an adverse rise in
chloride in the Haehanga Stream.
2.1.4.1 16 August 2012
The sampling run done on 16 August 2012 was done under high flow conditions
with 21 mm rain falling over the previous 48 hours. As a result, a reduced run was
undertaken. CBODF levels in the discharge were quite low and this is reflected in the
water quality down stream of the discharge. On

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.
1 The Council has used these compliance grading criteria for 15 years. They align closely with the 4 compliance grades in the
MfE Best Practice Guidelines for Compliance,

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
in a safe space. Yours Truly

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. In some circumstances
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.
