2.4      Recommendations from initial survey
The officer performing the initial investigation recommended that an investigation should follow up
on the results of the stormwater pollution in the Noosaville Industrial Estate and:
 Further identify any contributing factors of local industries impact to the pollution and
    contamination of Noosa’s Waterways with heavy metals and Hydrocarbons.
 Determine the source of hydrocarbons by initially inspecting sites within the Noosaville Industrial
    area that were previously required to hold an ERA license and determine their potential to effect
    of stormwater runoff polluting Eenie Creek.
