Page 1 of 8 Submission to: Parliament of South Australia Natural Resource Committee Enquiry Into Unconventional Gas (Fracking) Date: 30 January 2015 Contact: Peter Hackworth Executive Officer Wine Grape Council of South Australia Unit 4, 780 South Rd GLANDORE SA 5037 08 8351 4378 0439 182 411 www.wgcsa.com.au http://www.wgcsa.com.au/ Page 1 of 8 Summary of Recommendations WGCSA believes that approval for Unconventional Gas Extraction (UGE) projects should not be provided without scientific evidence that address the following concerns:  The ability of an extraction bore to maintain casing integrity and therefore isolation from aquifers, not just for the life of the extraction but for centuries after the mine closes  The contamination, as a result of well integrity failure on an aquifer used for irrigation and/or human consumption from: o chemicals/sand used to extract gas o methane and other extracted gases
