environmental impact is the alteration of land use, most likely from underdeveloped or natural land to excavations in the ground [1]. Social pressures like population growth can also cause the environmental impacts of these aggregate mining. Sand and gravel mining has been one of the serious environmental problems around the globe in recent years.

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.

cement, or some other construction use, it becomes clear that the environmental impacts of sand and gravel mining are widespread and cumulative. Below is a partial list of the potential cumulative impacts from the development of a typical sand and gravel mine: • Dust and diesel fumes generated on the haul road to and from the mine.

The most important effects of instream sand mining on aquatic habitats are bed degradation and sedimentation, which can have substantial negative effects on aquatic life. The stability of sand-bed and gravel-bed streams depends on a delicate balance between streamflow, sediment supplied from the watershed, and channel form.

created by mining that is 500 ft by 400 ft by 30 ft deep; in this area, sand and gravel was mined by dredging (Figure 5). Neither pit was dewatered. At both sites, there was no significant impact on ground-water levels from mining. The fluctuations that were seen in the monitoring wells were due to precipitation events (Figure 6).
