A parliamentary inquiry in New South Wales has heard alarming findings regarding contamination.

Despite tests indicating cadmium levels 50,000 times above the legal limit, the previous state government denied any contamination due to mining activities.

A couple who farm near Grenfell says they reported concerns about water pollution to government agencies for nearly a decade. 

Roughly 10 acres of their property housed a tailings storage facility (TSF) previously operated by the neighbouring Broula King Gold Mine to store mining by-products.

During the hearing, the couple discussed their efforts to alert the NSW Resources Regulator and Environment Protection Authority regarding leaks and seepage from the tailings storage and an adjacent small dam.

One striking revelation came in the form of a letter from former Liberal environment minister Matt Kean stating that there was no environmental pollution on their property. 

However, tests conducted by the EPA in 2015 at the pollution sources showed a staggering 50,000 times the allowable cadmium levels exiting these storage facilities.

The inquiry chair, Greens MLC Amanda Cohen, questioned the couple about the testing results, particularly focusing on the water's pH level, which was measured at 2.2, akin to stomach acid. 

In light of contamination fears, the farmers no longer engage in crop cultivation or livestock farming. They say decades of property rejuvenation have been thwarted by inadequate mining practices and regulations.

The Orange City Council also participated in the inquiry, with Chief Executive David Waddell emphasising the significant economic and social benefits brought to the community by the nearby Cadia gold mine.

However, he proposed the idea of establishing “no-go zones” in specific parts of regional NSW to prevent mining activities. 

He cited an instance where Fortescue Metals attempted drilling in Nashdale, a rural community west of Orange, home to numerous vineyards.

Mr Waddell speculated whether such zones could encompass high-quality agricultural areas, wilderness regions, and areas of scenic value, potentially alleviating the ongoing concerns.

The inquiry is ongoing.
