Council’s monitoring included 50 inspections, 53 water samples collected for
physicochemical analysis, review of consent holder and third party monitoring data, odour
surveys, ambient air quality analyses, ambient PM10 monitoring, and deposition gauging.
There were a total of eleven Unauthorised Incidents (UI’s) recorded in this catchment during
the period under review, only four of which could be substantiated at the time of investigation
by Council Officers. Only one of the substantiated
of partial restrictions expected for water users, with the exception of the
current RFWP which provide a protection limit of 77-87%.
