174 <br /> Phase I Environmental Site Assessment <br /> 5824 Morrow Mill Road <br /> Chapel Hill, North Carolina E S&ME Project No. 22580189 <br /> Bedrock <br /> According to the Geologic Map of North Carolina dated 1985, the subject property is primarily located over <br /> metamorphosed dacitic to rhyolitic flows and tuffs from the Late Proterozoic-Cambrian period. The northern <br /> portion of the subject property is underlain by metamorphosed argillite, mudstone, volcanic sandstone, <br /> conglomerate and volcanic rock from the Late Proterozoic-Cambrian period. <br /> Groundwater <br /> The source of groundwater in Orange County is precipitation in the form of snow and rain. A portion of the <br /> precipitation infiltrates into the ground and moves under the influence of gravity to the water table. Alamance <br /> County is an uplifted plain moderately dissected by streams. Inter-stream areas are generally low, and most of the <br /> larger streams are bordered by wide flood plains. <br /> Based upon a review of topographic maps, groundwater on the property is anticipated to generally flow to the <br /> northwest towards Back Creek. <br /> 4.4 Historical Use Information on the Subject Property <br /> S&ME reviewed historical use information from EDR as part of this Phase I assessment.
