Mining operations require water for their functioning directly and indirectly. Since a long time mining industry has been exploiting water without realizing the adverse impact it is having on the environment and the regional ecosystem. Acid mine drainage has become a major concern associated with mining.
This video focuses on training requirements and best practices for dredging operations that extract and process sand and gravel. Dredging is an aggregate mining activity, an operation usually carried out at least partly underwater, with the purpose of extracting material from the bottom and then sending it to the shore by pipelines or pontoon-mounted conveyor belts.

Total Water Use. In 2020, just over one billion cubic metres (m 3) of water was used to produce about 604 million barrels of oil equivalent (BOE) from oil sands mining, down from 2019 production of 630 million BOE (see the following figure). This decrease in oil sands production is the first since 2016 (2016 production was 4.7 million BOE less than the 2015 level).
