Document Summary
Remedial action plan: 3 stages: monitoring pollution, setting goals, operations and recommendations, remedial measures seeing how efforts are working. Ways of pollution (be able to distinguish: point-source pollution discharge of pollution from specific locations. Factory discharge, pipe draining into river, sewage treatment plants: non-point source pollution scattered or diffuse; no specific location of discharge. Air pollution (acid rain), agricultural fields, feedlots, golf courses: atmospheric pollution introduction of chemicals, particulate matter, etc. into the atmosphere. Plant nutrients and cultural eutrophication: oligotrophic bodies of water with clear water and low biological productivity, eutrophic bodies of water rich in organisms and organic material. Eutrophication process of increasing nutrient levels and biological productivity. Cultural eutrophication increase in bio productivity and ecosystem succession caused by human activities. Gold mining: gold = most polluting metal that is mined, heap leaching mining process where precious metals ( such as gold) are extracted by pouring cyanide solution over the ore.
