Red Creek Quarry Baseline Water Investigation Section 3 <br /> <br /> <br />3-2 <br />DRAFT for review purposes only. Use of contents on this sheet is subject to the limitations specified at the end of this docu ment. <br />The Smoky Hill Limestone/Shale overlies the Fort Hays Limestone and consists of up to 125 feet of <br />dark grey, thin-bedded limestone capped with a buff to yellowish tan, more thickly bedded limestone. <br />The Smoky Hills Member is generally considered overburden and will be removed during the mining <br />process. The Fort Hays Limestone is the primary resource unit due its high lime content. The Fort <br />Hays Limestone consists of approximately 35 feet of medium to light grey, distinctly bedded <br />limestone with numerous thin clay interbeds. Minor amounts of pyrite, both as nodules and as finely <br />disseminated crystals, are present in the Fort Hays Limestone. Below the limestone is the Codell <br />Sandstone consisting of approximately 20 to 30 feet of light grey, fine-grained, massive sandstone. <br />Contact with the overlying Fort Hays Limestone is denoted by 2- to 3-foot-thick transitional zone of <br />dense, arenaceous limestone. <br />Numerous fold and fault structures are found in and around the Site and generally trend to the <br />northwest (Scott 1972; Scott et al. 1978). Faults and fractures can be either a conduit or barrier to <br />groundwater movement on the Site. Mineralization within fractures has been observed on Site and <br />could be an indication of past water movement within these zones (Photo 3-1). <br /> <br />Photo 3-1. Mineralized Fracture within the Red Creek Drainage <br />The geology of the Site likely exerts a strong influence on local groundwater conditions and is <br />analogous to the geology found at the BCQ to the north. Previous groundwater studies performed at <br />the BCQ site (RGI 1999; BBL 2002; Arcadis 2012) have identified the local groundwater table occurs <br />within the Codell Sandstone, with groundwater generally flowing toward the Arkansas River. Similar <br />hydrologic conditions exist at the Site with groundwater within the Codell Sandstone flowing toward <br />Red Creek.
