Closing Down an Old Bore in Mildura

What closing down an old bore in Mildura actually involves

The Strategy says the older stock and domestic bores drilled into the limestone aquifer are likely to deteriorate as the steel casing corrodes, allowing water from the saline aquifer above to enter the fresher limestone aquifer and cause contamination. Its example is the Murrayville Groundwater Management Area, where it says failed or failing groundwater bores also present a threat to water quality. It does not say where else this happens, and Murrayville is not one of the localities this site lists.

What to ask

If you buy a property with a bore on it, ask whether it has been capped or closed down and by whom, and ask Lower Murray Water what applies to closing a bore. This site states no method and no price for the work.

The Commission's siting advice includes sealing a bore to prevent surface water or shallow ground water from contaminating the ground water; the siting page has it. The before you drill page says who to ask.
