Groundwater samples were obtained on two occasions in the vicinity of the Cheal wellsites during the
monitoring period. This sampling is a continuation of the groundwater monitoring component of this
programme which was initiated during the 2013-2014 monitoring period.
Four monitoring sites were sampled during the review period, including two dedicated monitoring bores
which were installed by the Company under the conditions of consents 10254-1 and 10304-1.1. One in the
vicinity of the Cheal-B

Council’s monitoring programme for the year under review included two inspections and eight water
samples collected for physicochemical analysis during the reported period.
Elevated zinc concentrations were recorded in the receiving waters upstream and downstream of the
Company’s discharge. The historical disposal of galvanising waste materials into a bore on the Company’s
site is considered to be the most likely source of zinc contamination in this discharge, and in the unnamed
tributary of the
26 June 2017. At the end of the review period this incident was still being investigated.
The historical disposal of galvanising waste materials into a bore on the Company’s site is considered to be
the most likely source of zinc contamination in this discharge, and in the unnamed tributary of the Kahouri
Stream. However results from the current monitoring period suggest that zinc levels continue to remain
relatively stable and are decreasing over time in the receiving environment.
In the
taken. For s14(3)(b) and more permanent minor takes such as dairy shed use, this
would be an expensive requirement. For groundwater, Rule 48 stipulates limits for flow
rate and maximum daily volumes, although the adverse effects requirements are more
readily complied with, in the main being specifics for the location of the bore away from
the sea, surface water bodies, and other groundwater users.
As noted above, some councils don’t stipulate a Permitted Activity limit, they just

Effects to groundwater could not be assessed as no groundwater monitoring is undertaken at the site. To
enable groundwater sampling to be undertaken in the future a recommendation to install a monitoring
bore at the site has been included in Section 4 of this report.
In the upcoming monitoring period further sampling of the Makara Stream has also been recommended to
ensure that the installation of the
