F. <br /> <br />reauest. <br /> <br />Accompanying this submittal is geologic and other data taken <br />from the approved County and MLRB plan and other subsequent <br />submittals. Below is also a general summary of this and other <br />known data of geologic and hydrologic conditions in the area. <br />No in-depth new reports or data has been generated for this <br />application, as the intent of this application is to limit any <br />potential impact to groundwater by limiting the type of fill <br />material to a very specific type of inert fill only. <br />Geoloaic Soils and Core Drilling data taken from the <br />original submittals are depicted as Map #2. The <br />site is located in the South Platte River alluvium <br />with 40+~ of sand and gravel deposits into the <br />water table. The site is being mined for the sand <br />and gravel deposits to the depth of the resource to <br />clay/shale bedrock. <br />fiydroloaic Water data taken from a dewatering application <br />that was proposed several years ago, shows the <br />location of all shallow wells in the area. <br />Please ignore the drawdown limit line, since <br />the dewatering was not approved and has never <br />been undertaken. These are depicted as Maps <br />#3 & 4. Behind these two maps is a list of <br />shallow wells that are closest to the <br />facility. <br />The shallow groundwater flow is from southeast <br />to northwest toward the South Platte River. <br />Most, if not all, of these shallow wells are <br />utilized only for irrigation purposes as most <br />homeowners in the area have non-tributary <br />Arapahoe or other deep wells for domestic <br />water supply. This is because that, although <br />the water from the shallow wells do meet <br />drinking water standards, it is high in <br />farming related constituents (nitrates, etc.). <br />In addition, some of the shallow wells have <br />shown minute concentrations of contamination <br />from the Rocky Mountain Arsenal. <br />The closest municipal water supply wells into <br />the shallow alluvium aquifer is located 5+ <br />miles northeast in Brighton for the City of <br />Brighton. These wells are not located in the <br />direction of prevailing shallow alluvium <br />groundwater flow, so that there are negligible <br />domestic water supplies that could be <br />affected. <br />
