Water Depletion & Contamination
Croell’s well permit will allow pumping 6.4 MILLION gallons of water each year. There are over 100 wells within approximately 2 miles of the pit. An expert witness from the SDSM&T Department of Geology & Geological Engineering Department has calculated a possible drawdown of up to 60 feet at 1 mile from the Croell well. In addition to lowering the water table, the risk of contamination is great with how the water is obtained, used and treated in mining operations! Our water is far too precious of a resource to risk!!
Furthermore, the quarry requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal wildlife, it also leads to a huge loss of biodiversity as plants and aquatic habitats are destroyed. Moreover, adjacent eco-systems are affected by noise, dust, pollution and contaminated water.
The pit will disrupt the existing movement of surface water and groundwater as well as interrupting natural water recharge which can lead to reduced quantity and quality of drinking water for residents and wildlife near or downstream.
