Note: All consents issued will require an exclusive discharge to land and full storage after
1 December 2022. This means that any consented discharge expiring in 2022 or later
must discharge to land when the consent is renewed.
Dual discharges may be allowed if the farm is in a high rainfall area
concentration levels remained relatively stable in the other bore. The third bore
remained dry for the entire monitoring period, which could potentially be attributed to the relatively
low rainfall in the area during the past year.

and unaffected by the landfarming activities.

During the period under review, five inspection visits were carried out in relation to
consents 7470-1 and 7470-1.1. The following observations were recorded:
4 July 2013
Repairs that had been made to GND2102 by Harry Dixon of Strata Drilling were
inspected. The protective casing had been extended up by 2.65 m, preventing rainfall
runoff from entering the bore at the surface. Manual water level measurements were
carried out at GND2010, GND2102, GND2103 and GND2104. No abstraction occurred

drain developed farmland. There was no evidence of any groundwater infiltration from the

approximately 3.5 km south of the site.
An issue with the data being obtained from GND2103 was discovered in mid 2013.
