(enlarged joints) prior to the blast. The blasting shook the limestone and the ground water and released some sediment. In an older well finished in the surface limestone deposit, this mechanism could cause turbidity levels to increase after a blast. Figure 3. Monitoring showed slight turbidity increases after blasting at Fountain.
Limestone mines use two types of blasting. Small explosive charges set along drilled lines free blocks of stone to be removed for construction. Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust.
