The South Australian Opposition is calling for a full parliamentary inquiry into the Edwardstown groundwater contamination scare.



The Opposition is demanding an inquiry as new revelations that concerns about contamination at the former Hills Industries site were raised as early as 2007.


The EPA last week confirmed that toxic chemicals had infected groundwater near the site and warned residents at more than 2000 homes not to use bores.


Water Minister Paul Caica yesterday deflected Opposition calls for a parliamentary probe into the matter and accused rivals of manufacturing "unnecessary fear and anxiety".


Deputy Opposition Leader Mitch Williams said an inquiry was needed to determine when the Government first learnt of the contamination and if the EPA's fears of potential health risks should have been made public sooner.


An EPA spokeswoman said the organisation would make more information on contaminated zones across the city available on its website.
