what are the environmental effects of limestone quarrying?
Usually, limestone quarrying just has one effect… a very large hole. If you have a problem with water in the quarry and the quarry is next to a river, you could have a problem with alkali runoff, but usually a quarry is lower than anything but an underground river system, with most of the water being contained in the quarry itself. I guess we learned a long time ago, that people are really really greedy and stupid, so its POSSIBLE that some moron could pump the limestone water out into a local river…. but imagine the level of stupidity that would take?
