the extent of historical filling in the area as shown in Figure 3. During the year under review,
monitoring showed that the levels of BOD, unionised ammonia and ammoniacal nitrogen were elevated in
relation to the landfill tributary, which may have been as a result to the high rainfall and agricultural
activities around the headwaters of the roadside tributary.

A total of 65.5 mm rainfall had been recorded in the previous week at NPWWTP,
58 mm of which fell during the day prior to the inspection. This had rapidly filled the
site's stormwater ponds. While the water was being tested by DAS on the afternoon of
the 17th March, permission was sought and given by the Council to allow the ponds to

SENZL monitors the combined stormwater discharge from the site, with sampling
triggered by rainfall events. Table 3 shows the results obtained during the 2015-2016
monitoring year. Hydrocarbons, suspended solids and chloride levels were all below

(planktonic). During the summer months,
increased water temperature, reduced rainfall
and increased daylight hours provide ideal
conditions for cyanobacteria to grow, sometimes
resulting in algal blooms. When in bloom,
cyanobacteria can produce toxins that can pose a
risk to the health of people and animals entering
the water.
Sites monitored for benthic cyanobacteria were
