surface mining‚ leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite‚ a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab‚ you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated. Materials: (3) 100 mL Beakers 1 tsp. Crushed pyrite 1 tsp.

Contamination: Of the United States population‚ over 50% depend on groundwater for drinking water and so do other living organisms. We use groundwater to bathe‚ to cook food with‚ and to drink with. But‚ when groundwater contamination occurs which is when man-made products such as road salts‚ chemicals‚ gasoline and oil get into the groundwater‚ it causes the water to become unsafe and unfit for living organisms use. If the groundwater becomes contaminated‚ it has some serious health effects such as

Water is found in surface water and groundwater; in terms of surface water it is found in rivers‚ ponds‚ lakes and streams while groundwater occurs beneath the surface within the saturated zones where the hydrostatic pressure is equal to or greater than atmospheric pressure and can be found in wells and boreholes in this project and we will

Groundwater Debate Has anything you want or need in your life been cut off from you? Well‚ California is debating on whether or not to pass a law throughout the state that will regulate the groundwater that both residents and farmers are allowed to use over a specific time. If this law is passed‚ farmers will have a much more difficult time attempting to grow their crops‚ but on the other hand‚ the residents of towns that are completely water deprived will gain water for them to use instead of having
