Annual Site Environmental Report for 1999 Geologic and Hydrogeologic Selting The Paducah Site, located in the Jackson Purchase region of western Kentucky, lies within the northern tip of the Mississippi Embaymentp
Paducah Site at the south end of the plant. The sediments deposited on this erosional surface are termed continental deposits. The lower portion of the continental' deposits dmsists of approximately 9 m (30 ft) of stream gravel and sand. Over time, sediments from the retreating glaciers dammed the river valley, causing the formation of a lake. Silts and clays with thin zones ofsapd and occasional gravel were deposited in the lake, forming the upper portion of the continental deposits. These deposits range from approximately 1.5 to 17 rh (5 to 55 ft) thick. Finally, loess, a wind~blown silt, overlies the continental" deposits throughout the site. Thickness of loess deposits varies f~om approximately 1.5 to 8 m (5 to 25 ft), averaging approximately 4.6 II1 (15 ft). 'The local groundwater flow system at the Paducah, Site contains four major components: the McNairy flow system, the Regional Gravel Aquifer (RGA), the Upper Continental Recharge System (VCRS), and the terrace gravels. • The McNairy flow system consists , of interbedded and interlensing sand, silt, and clay of the McNairy Formation. "Sand facies ,account for 40 to 50% of the 'total formation thickness of approximately 69 m (225 ft). • TheRGA consists of san4 and gravel facies in the lower continent3I deposits, gravetand coarse sand portions in the upper McNairy that are directly adjacent to ,the lower continental deposits, coarse~ grhlned sedimfmts at the base of 'the upper continental deposits, and alluvium adjacent to the Ohio River. These depo'sits have an average thickness of 9 m (30 ft) and range up to 21 m (70 ft) along an axis that trends east-west 'through the site. The RGA is the uppermost and primary aquifer, formerly used by private residences north of the Paducah Site. • The UCRS consists mainly of clayey silt with interbedded sand and gravel in the upper continental deposits. The system is so named because of its characteristic recharge to the RGA. • The terrace gravels consist of shallow Pliocene gravel deposits in the southern portion of the plant site. These deposits usually lack sufficient thickness and saturation to constitute an aquifer but 'may be an important source of groundwater recharge to the RGA. Groundwater flow ongmates south of the Paducah Site within Eocene sands and the terrace gravels. Groundwater within the terrace gravels either discharges to local streams or recharges the RGA, although the flow regime of the terrace gravels is not fully understood. Groundwater flow through ,the UCRS is ultimately downward, also recharging the RGA. From the plant site, groundwater flows generally northward in the RGA toward the Ohio River, the local base level for the system. Uses of Groundwater in the Vicinity The WKWMA and some lightly populated farmlands are in the immediate vicinity of the Paducah Site. Homes are sparsely located along rural roads in the vicinity of the site. Three communities lie within 3.2 kilometers (2 miles) of the plant: Magruder Village to the southwest and Grahamville and Heath to the east. Both groundwater and surface water sources have been used for water supply to residents and industries in the plant area. Wells in the area are screened at depths ranging from 4.6 to 75 m (15 to 245 ft). The majority of these wells are believed to' be screened in the RGA. The Paducah Site continues to provide municipal water to all residents within the area of 9-8 ' Groundwater
