�I 1I <br /> Transit Mix Concrete Co. <br /> Chemistry data for the LTC-GW-1 location are representative of groundwater in the granodiorite <br /> rocks west of the West Fault that are discharging into Little Turkey Creek. The water chemistry <br /> indicates a sodium- sulfate type with high total dissolved solids (TDS). <br /> The high TDS suggests that the ground water in this area of the HRR site has resided within the <br /> groundwater system for many years. This is consistent with low bulk hydraulic conductivities and <br /> resulting long groundwater travel times from the ridge recharge areas to the Little Turkey Creek <br /> discharge areas, as described in more detail in Attachment G-2. The sharp contrast with surface <br /> water chemistry in the same general location (LTC-2 in Table G-21B) that shows low TDS and a <br /> calcium-bicarbonate type, indicates that groundwater discharge makes up a very small proportion <br /> of the surface water flow along this reach. <br /> Chemistry data for the LTC-GW-2 location are representative of groundwater in the granodiorite <br /> rocks east of the West Fault that are being recharged by surface water in Little Turkey Creek. <br /> The groundwater chemistry has very similar characteristics to surface water chemistry in this <br /> location (LTC-1 in Table G-2A) with low TDS and a calcium-bicarbonate type. The very similar <br /> chemistry suggests that surface water recharge makes up a very high proportion of the <br /> groundwater storage in this location. The chemistry data supports the interpretation of <br /> groundwater flow that was based on potentiometric data indicating that surface water recharges <br /> the underlying groundwater at this location. <br /> e. Domestic and Community Wells <br /> There are no domestic or community groundwater wells within the proposed disturbance area <br /> located in Section 16 of the Ranch property or within 600 feet of the proposed Quarry. Seven <br /> groundwater monitoring facilities were established within the proposed mine area in 2017. <br /> Domestic groundwater wells are present in the valley bottoms of Little Turkey Creek in Section 17 <br /> upstream of the Ranch property. The water levels in domestic and monitoring wells within the <br /> Little Turkey Creek valley bottoms west of the West Fault are similar to the creek elevation, <br /> suggesting that shallow ground water levels within the Little Turkey Creek valley bottom are <br /> controlled by the Little Turkey Creek water elevation. <br /> All mining will occur above the Little Turkey Creek elevation. There will be some interception of <br /> groundwater within the fractured granodiorite rocks to the south of Little Turkey Creek. Given <br /> the low bulk transmissive capacity of the fractured rock within the ridge area south of the Little <br /> Turkey Creek valley (see Attachment G-2 for details), water balance evaluations indicate that <br /> the amount of groundwater intercepted by planned mining operations will be insignificant relative <br /> to the prevailing hydrology at the site. Ground water intercepted by the Quarry will be re-directed <br /> back to Little Turkey Creek with minimal evaporative losses using temporary settlement basins. <br /> Hitch Rack Ranch Quarry Permit Application M-2016-010 <br /> October 3, 2016 G-37 <br />
