Legislative Council Fifty-Third Parliament, Second Session (53-2) 53 2 Parliament of South Australia Legislative Council published Question Time Water Quality Water Quality The Hon. M.C. PARNELL Legislative Council Water Quality The Hon. M.C. PARNELL (15:02): I thank the minister for his answer, but will he take on notice that part of my question that related to his investigating the potential future safety of Adelaide's water because the chemical that I am talking about is in fact a by-product of the chlorination process—the more chlorine you add, the more of these toxic, carcinogenic by-products you get? Could the minister take that on notice? The Hon. I.K. HUNTER Legislative Council Minister for Sustainability, Environment and Conservation, Minister for Water and the River Murray, Minister for Climate Change Water Quality The Hon. I.K. HUNTER (Minister for Sustainability, Environment and Conservation, Minister for Water and the River Murray, Minister for Climate Change) (15:02): I am very happy to indicate that I will take that on notice and try to get some advice from the Department for Health and Ageing as well for the honourable member in relation to that chemical in particular. But, of course, unless you are using some other form of disinfection, which probably has cost impacts as well, we will probably always be in a position where we need to use chlorination for our water system in this state.
