A second method is insitu leaching. Groundwater and certain geochemical conditions must be present in order to utilize this method. During insitu leaching, rather than physically mining and removing overburden to reach copper deposits, chemicals are introduced into ore bodies using injection wells.

8 Fate and Transport of Pesticides Soil and Water

The agricultural production systems of the United States are capable of producing a bountiful supply of food and fiber, but at some cost to the nation''s water, soil, and air resources.As agricultural production intensified, the natural pestpredator relationship that keeps many crop pests in check was disturbed. This contributed to the increasing use of pesticides.
