Environmental Science Unit 5 Test Review

Acid mine drainage causes an increase of heavy metals to enter the environment. Why does this happen at mining sites?

• The processing of ore at mining sites

• The ore left behind in the mine leaches into the ground

• Most mining practices increase the amount of precipitation in the area which results in more groundwater recharge

• The pilings weather away faster than if they were still in the ground
