We have carried out an assessment on the environmental effects of limestone quarrying on some communities in the Lower Manya Krobo District in the Eastern region of Ghana. Dust emission is one of the major effects of the practice of limestone extraction and as such, dust (PM10) sampling was conducted at the affected communities.

Quarrying also removes the entire subcutaneous (epikarstic) zone which is an important ground-water store, together with part or all of the unsaturated zone. Pumping of water from the excavation will change the ground-water balance and can alter the direction and amounts of conduit flow, particularly if the quarry extends beneath the water table.

Property values drop when a quarry is built. Over the past twenty years, the evidence is clear. Scientific methods have been developed to account for other factors such as the size and location of the property, the local environment, age of the house etc., so that the effect of property value changes caused only by the quarry can be calculated.

The results of these models show that quarrying activities reduce flood hazards by creating catchments basins which detain and delay floodwaters during extreme rainfall. As opposed to public belief, the simulated maps show that quarrying does not enhance flood hazards and in fact mitigates its effects.

Quarry. Sand, gravel, and crushed rock quarries employ standard surface- mining techniques. Crushed stone is used for concrete aggregate, for road building, and, in the case of limestone, as flux in blast furnaces and for chemical applications. The quarrying technique consists of drilling and blasting to fragment the rock.
