LGS EROL O control, the influence of the plant site upon the regional groundwater is negligible. 2.4.10.2.5 Seepage From the Spray Pond Groundwater levels measured in observation wells, indicate that seepage from the planned spray pond, shown in Figure 2.4-12, will flow in two directions; southwest, toward the Schuylkill River, and to the north. The seepage may cause a groundwater mound beneath the pond, and minor, local reversals of flow direction, as suggested by the flow net construction shown in Figure 2.4-12. This would increase the groundwater flow to the north, but the general directions of flow would remain the same. Groundwater levels beneath the plant site will not be significantly affected by these seepage losses.
~
Seepage losses from the spray pond were calculated for an unlined pond by taking the difference between the preconstruction groundwater underflows, and the total underflows expected after the spray pond is constructed. Two methods were used to calculate the total underflows using Darcy's law: (1) computation of underflow through a cross flow area, and (2) construction and analysis of a flow net. After the spray pond is operating, the differential head between O the spray pond surface and the Schuylkill River will be 140 feet. For flow in a northward direction, the differential head between the spray pond surface and the discharge area is estimated to be 50 feet. An effective thickness of potential aquifer (the saturated thickness will depend upon how high the groundwater mound rises) of 140 feet was used because of the reduction in number and size of fractures at that approximate depth, as observed in the cored holes. A permeability of 200 feet per year was used as an effective value for the residual soils and bedrock materials. Using these parameters, underflows were determined by analysis of the flow net in Figure 2.4-12 to be 5.3 x 10* ft3/yr towards the Schuylkill River, and 1.6 x 10* ft3/yr toward the north, giving a j total underflow of 6.9 x 108 ft3/yr. The second method of analysis, the cross-sectional area method, 0 = KIA, indicates that 4.5 x 10* ft3/yr will flow toward the Schuylkill River, and i 1.7 x 108 ft3/yr will flow toward the north, giving a total i underflow of 6.2 x 10* ft3/yr. ! Preconstruction underflow was calculated using Darcy's Law O = KIA.' The hydraulic gradient (I) was determined from equipotential contours of the groundwater table, shown in Figure 2.4-11. The thickness of saturated material above a depth of 140 feet, the effective aquifer thickness, is estimated to be O
\_ /
110 feet. The permeability (K)'is 200 feet per year, as described above. ' Based upon these parameters, present underflow l 2.4-13 r

LGS EROL beneath the pond was estimated to be 2.74 x 10* ft3/yr toward the Schuylkill River, and 0.54 x 106 ft3/yr toward the north. Total preconstruction (natural) underflow, then is the sum of these, or 3.3 x 106 ft3/yr. Therefore, the estimated seepage loss from an unlined spray pond is: (6.9 x 106) - (3.3 x 106) = 3.6 x 106 ft3/yr (flow net (2.4-1) method) (6.2 x 106) - (3.3 x 106) = 2.9 x 106 ft3/yr (cross-sectional area method)(2.4-2) Actual steady-state seepage losses could be higher if untreated open joints or fractures were present in the pond bottom. It would be difficult to preclude this possibility, even with intensive surface and subsurface investigations to determine localized fracture permeabilities; therefore, the spray pond was lined with a soil-bentonite liner I foot thick, having a permeability of less than 1 foot per year. This ensures that the seepage loss calculations are conservative, by preventing potentially higher rates of seepage through localized fracture zones. Monitoring of water levels in the observation wells during plant operation will provide information on variations in the potentiometric surface resulting from recharge through precipitation, and from operation of the spray pond, and will ll provide additional data on the direction of groundwater movement. 2.4.11 REFERENCES 2.4-1 U.S. Geological Survey, Water Resources Data for Pennsylvania, Part 1, Surface Water Records, Annual Publications, Water Years 1965-1980. 2.4-2 U.S. Geological Survey, Surface Water Supply of United States, Part 1-B, Annual Water Supply Paper Series through 1960 Water Year. 2,4-3 U.S. Geological Survey, Surface Water Records of Pennsylvania, Annual Publications, Water Years 1961-1964. 2.4-4 U.S. Geological Survey, Compilation of Surface Water Records through September 1950, Water Supply Paper 1302, Part 1-B, 1960. 2.4-5 U.S. Geological Survey, Water Supply Paper 1722, Compilation of Surface Water Records, October 1950 to September 1960, Part 1-B, 1964.

LGS EROL f'T x/ 6.1.5.2.6 Milk Milk samples will be collected and analyzed from three available locations within 5 km (three miles) having the highest dose potential (10B1, SC1, 10C1) and at a control location (22F1) approximately 15 km from the plant in the least prevalent wind direction. Samples will be collected bi-weekly during the grazing season and monthly at other times. To increase program coverage, an additional eight stations have been added to the milk sampling program and will be collected monthly. 6.1.5.2.7 Vegetation Broad leaf vegetation will be sampled and analyzed monthly during the growing season at a location near the site boundary in the sector with the highest annual average D/0 (11S1). 6.1.5.2.8 Fish f'~g Although there are presently no commercially important species in (,) the vicinity of the discharge, two species of recreationally important fish, sunfish and brown bullhead, will be sampled if available. Fish will be sampled semi-annually at three locations: an upstream control in an area not influenced by plant discharge (33A2), a location in the vicinity of the discharge point (16B2), and a downstream area (16C4). 6.1.5.2.9 Game A sample of small game animals.will be obtained and analyzed annually from the vicinity of Limerick. i 6.1-59 Rev. 18, 06/84
