According to the EPA Victoria’s 2006 Environmental Audit of the Goulburn River – Lake Eildon to The Murray River,  the mean annual concentration for Amitrole T in the Central Goulburn and Shepparton Irrigation Areas was estimated to be above the Australian Drinking Water Guidelines by over 250%. As a result of the EPA audit, Goulburn Murray Water had to test for Glyphosate, Amitrole, 2,4-D and AMPA over a 3 year period. (Guideline Heath limits for Amitrole are 10ppb, Glyphosate 1000ppb and 2,4-D 30ppb).

The first test results were disturbing – It is unknown whether the testing has continued.

On the 12th of April 2006, the following levels of Glyphosate and AMPA were recorded in Drain 8, Ardmona, Midland Highway. Glyphosate 10,500ug/L, AMPA 830ug/L. These are likely to be the highest levels of either substance recorded in Australia. These levels are high due to Glyphosate being used against aquatic weeds.
