The Nova Scotia government has not notified some landowners of potential contamination on their properties from historical gold mines, despite being required to do so by provincial regulations. Gold mines that operated in Nova Scotia dating back to the 1800s left a legacy of contamination, most notably from arsenic and mercury. In many cases, the original source of the contamination is on one property, but the material flowed — often through water — to surrounding properties over time.
How microbes could help clean up Nova Scotia's abandoned mines
Researchers from three Maritime universities are hoping microbes collected from the bottom of a lake near an abandoned gold mine in Dartmouth, N.S., will provide a model for how to clean up contaminated sites across the province in a quicker and less-intrusive way. Last May, a research team took a boat to the middle of Lake Charles, not far from the former Montague gold mine, where extensive mining took place from 1860 to about 1940.
