Sand is vital for sustenance of rivers and uncontrolled sand quarrying from the riverbed leads to the destruction of the entire river system. Continuous sand and gravel extraction in quantities higher than the capacity of the river to replenish them is leading to changes in its channel form and eventually erodes the river banks.

Other potential quarrying effects which are of concern to environmentalists include biodi-versity loss, land degradation, nuisance effects, reduced plant growth, etc. Particulates are the tiny solid or liquid particles that are suspended in air and which are usually individually invisible to
Manifestations of specific impacts are on the air, water, soil, earth surface, flora and fauna, and human beings Areola, 2012. Apart from land degradation, other negative impacts of quarrying includes swamp creation, deterioration of ground water, erosion of soil, noise and percussions from rock blasting, generation of dust, smoke and fumes production of noxious gases and ground vibration.
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.
