Introduction. Mining of natural aggregates, including both sand and gravel and crushed rock, represents the main source of construction aggregates used in the US and throughout the world. 1 Indeed, each year more than 2.6 billion tons of aggregate are used in the US or nearly 10. tons per capita. Mining of aggregate frequently generates …

The most obvious environmental impact of aggregate mining is the conversion of land use, most likely from undeveloped or agricultural land use, to a (temporary) hole in the ground. This major impact is accompanied by loss of habitat, noise, dust, blasting effects, erosion, sedimentation, and changes to the visual scene.
