svncline . (Exhibit TV-D-1) <br /> The Mesaverde west of the lease area is <br /> overlain by a thick sequence of younger sediments which <br /> comprise the ivasatch and Ohio Creek Conglomerate, and which <br /> are overlain by the Green River formation, to the north and <br /> west of the lease area, towards the Piceance Creek Basin . <br /> The Mesaverde aquifers are not used for <br /> domestic or industrial water uses in the mane plan or adjacent <br /> area and are not extensively used as aquifers elsewhere in <br /> the Piceance Creek Basin . Discharge occurs regionally at a <br /> few artesian wells and it is unlikely that discharges occur <br /> locally to streams or springs . <br /> There are no wells penetrating the Mesaverde <br /> within the mine plan or adjacent area . Because of the <br /> westward dip of the formation into the Piceance Creek Basin, <br /> the Mesaverde is generally too deep to be accessible for <br /> domestic water wells . <br /> Groundwater quality information is limited <br /> `or the Mesaverde sandstones . Broaden and Giles located oniv <br /> one well in the Mesaverde in their studv of the Cattle Creek <br /> and Crystal dyer Drainage Basins . •later from t :is well was <br /> reported to be a calcium bicarbonate having a total dissolved <br /> solids concentration of 181 milligrams par liter (m„/ l) , <br /> Two primary shallow unconsolidated aquifers <br /> exist in the Coal Basin Mine plan and adjacent area . They <br /> are t?-:e alluvial sands of Coal Creel-, and its tributaries , <br /> 25 <br />
