In the 2022-2023 period, the Council was not required to undertake
marginal rise in analytes in one of the bores,
whilst 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.
Lake Taumaha sample analysis demonstrates that the surface water quality continues to remain stable and
unaffected by the landfarming activities.
Soil sample analysis found that further bioremediation would be
the
second inspection there had been 16.5mm of rainfall at the Waiwhakaiho meteorological station. The
pond was full and flowing slowly to the vegetated swale. The flow into the farm drain was a trickle and
could not be sampled.
The consent also imposes contaminant limits on water quality of the farm drain beyond a mixing zone
of approximately 7m. During each inspection there was no water flow in the farm drain. The second
inspection noted a few puddles in the drain. The drain is well
moderate temperatures and regular rainfall, but when the rainfall is heavy it can
cause flooding and landslips. In periods of low rainfall, the region can experience droughts. In some parts
of the region, and at certain times of the year, storms and tornadoes are a reasonably frequent occurrence.
Coastal erosion
Coastal erosion is the retreat of the shoreline caused by water currents, waves, and wind. It is a natural
process that can be influenced by human activity. The Taranaki coastline
