 Concrete spill in gutter                                Gutter after clean-up


It is more than likely that each of the concrete batching plants in Noosaville industrial estate could
have contributed to the concrete looking milky substance found in drain 2. There was also a large
fresh pour of concrete conducted a couple of days before photos were taken on 13th January 2017
This may also have contributed to the concrete looking milky substance found in drain 2, and to the
spike in pH, phosphorous and turbidity levels in the water samples taken during the survey. Refer to
Charts 11-15.
