Sand and gravel mining: effects on ground water resources

2008-2-8  Another effect of sand and gravel mining is the loss of the protection provided by soil as it filters out pollutants (Rutherford et al. 1992; Kalbitz et al. 2000). Removing the organic layer of soil found on the surface of sand and gravel deposits decreases the soil’s capacity to absorb contaminants and thus clean water as it passes through its pores.

By removing too much sediment from rivers, sand mining also leads to the erosion and shrinking of river banks. Deltas can recede due to sand mining. All of these destructive effects of sand mining ultimately lead to the loss of fertile land and property.
