Nova Scotia’s Auditor General Concerned about Mine Contamination

In a recent report issued by Nova Scotia’s Auditor says more work needs to be done to address contaminated mine sites throughout the province.

“I drew attention to this accounting because the cost to clean up the province’s contaminated sites could significantly change in the future as the province collects more information on these sites,” Michael Pickup, Nova Scotia’s Auditor General said.

This was the first year the report drew attention to accounting for contaminated sites. The report showed that contaminated site liabilities increased to $372 million in 2019 compared to $107 million five years ago.

According to Pickup’s report, the Department of Lands and Forestry’s investigations of contamination at abandoned mine sites is lacking, leaving a risk of unknown financial, ecological and human health concerns. The report also found an additional 63 mine sites with no liability for remediation because the contamination extent is unknown.

“Those sorts of legacy sites, unfortunately, date from a period in which there really wasn’t environmental science and people just didn’t have a good understanding of our impact on the environment,” says Sean Kirby, the Executive Director of the Mining Association of Nova Scotia.
