• Based on my experience and the information available on Front Range aquifers,with <br /> this degree of fracturing and faulting the surface and ground waters are going to be <br /> in communication. <br /> o In the Pikes Peak granite almost all effective permeability and porosity will <br /> be provided by fractures. The amount will vary depending upon the amount <br /> of stress and weathering. To some degree this should be true for all the <br /> aquifers in the quarry site. <br /> • The intersection of the creek bed fault zones and the thrust faults in these fractured <br /> rock aquifers should not provide an effective aquitard. <br /> o If the thrust faults are "sealed" it is very doubtful that sealing would be <br /> continuous <br /> o The fault planes are as likely to provide a conduit as a barrier. <br /> In the setting detailed above and with the removal of 393 acres of material with <br /> blasting it is impossible to predict that ground water and surface water flow,and <br /> therefore aquifer recharge,will not be significantly altered. These changes could <br /> cause the stoppage or reduction of the ground water supply to residents. <br />
