Theminingofaggregatesin rivers can have an effect on pollution and change the level of water acidity (pH). Removing sediment from rivers causes the river to cut its channel through the bed of the valley floor (or channel incision) both upstream and downstream of the extraction site.

Quarry products, such as construction aggregate, are produced in a multi–stage processing operation that involves drilling and blasting, extraction, crushing and milling, screening and classification. As part of the MIST programme, the BGS reviewed current production practices.
