See how water quality in the Dominican Republic's Margajita River has improved since Barrick's Pueblo Viejo gold mine opened in 2012.<br /><br />The river used to be colored dark red due to untreated, acidic water discharged by a previous mining operation. Barrick's state-of-the-art water treatment plant now treats all water from the mine site to international standards.<br /><br />Also, people who live in communities around the mine have been invited to participate in the mine's environmental monitoring program.
