These mine wastes, or tailings, can contain up to three dozen dangerous chemicals, including arsenic, lead, mercury, and cyanide.
Each year, mining companies dump over 180 million tonnes of these hazardous mine wastes into rivers, oceans, and lakes - that's more than 1.5 times the amount of waste that US cities send to landfills each year.
The report calls on mining companies to stop using our oceans, rivers, and lakes as dumping grounds for their toxic wastes. The report recommends additional steps that must be taken by mining companies to protect people and ecosystems from irresponsible aquatic waste disposal, including dry stacking and backfill, where safe, and adopting measures to produce less waste.
