4. Results
From 1 November 2012 to 27 March 2013 a total of 13 samples were collected at each
site for the purpose of state of the environment monitoring (SEM). Whenever possible,
no SEM sampling was undertaken within three days following significant river
freshes. However, occasionally sampling was affected by localized rainfall and
rainfall or freshwater.
The guideline MfE ‘Action’ mode is reached when enterococci counts in two consecutive
samples exceed 280 enterococci cfu/100 ml. No site reached Action mode during the 2014-
2015 season and no individual sample exceeded 280 enterococci cfu/100 ml.
Mann-Kendall tests were performed in order to assess long term trends in microbiological
water quality. Two sites show a significant decrease in median enterococci counts over the 13-
20 years monitored (Fitzroy and

leachate and contaminated stormwater from three main processing areas. These are the drilling
wastes pad (pad 3) and two composting pads (known as ‘pad 1’ and ‘pad 2’).
Drilling muds, fluids and cuttings are mixed with sawdust or other organic material and then piled up on the
drilling wastes pad. Any rainfall runoff and leachate that is generated, drains into a series of ponds for
treatment. Between each pond is a baffle that skims off any floating hydrocarbons as the leachate passes
through.
