Gulungul Creek monitoring data 2002-2010

The graphs on this web page show the following key chemical indicators for the 2007-10 and the 2002-07 wet seasons.

The Supervising Scientist's interpretation of the data in these charts is available at:

Uranium in Gulungul Creek

The uranium limit of 6 µg/L recommended by the Supervising Scientist has been derived using local ecotoxicological data in accordance with the Australian Water Quality Guidelines to protect 99% of the species present. The limit must not be exceeded. Please note that the limit is far above the range shown on the charts, but the scale on the right hand axis shows how the measured concentrations compare to the limit.
