<Li> Construction aggregate (sand and gravel) </Li> <P> Many quarry stones such as marble, granite, limestone, and sandstone are cut into larger slabs and removed from the quarry . The surfaces are polished and finished with varying degrees of sheen or luster . Polished slabs are often cut into tiles or countertops and installed in many kinds of residential and commercial properties . Natural stone quarried from the earth is often considered a luxury and tends to be a highly durable surface, thus highly desirable . </P> <P> Quarries in level areas with shallow groundwater or which are located close to surface water often have engineering problems with drainage . Generally the water is removed by pumping while the quarry is operational, but for high inflows more complex approaches may be required . For example, the Coquina quarry is excavated to more than 60 feet (18 m) below sea level . To reduce surface leakage, a moat lined with clay was constructed around the entire quarry . Ground water entering the pit is pumped up into the moat . As a quarry becomes deeper, water inflows generally increase and it also becomes more expensive to lift the water higher during removal; this can become the limiting factor in quarry depth . Some water - filled quarries are worked from beneath the water, by dredging . </P> <P> Many people and municipalities consider quarries to be eyesores and require various abatement methods to address problems with noise, dust, and appearance . One of the more effective and famous examples of successful quarry restoration is Butchart Gardens in Victoria, BC, Canada . </P>
