Based upon tbe recent hydrogeological investigation conducted, sites along the Missouri River near Calloway, Missouri would be favorable: for development using a horizontal collector well. Evaluation of the aquifer testing indicates that the aquifer transmissivity near the test pumping well is in the range of 450,[){)0 gpd/ft (57" F'), with a saturated aquifer thickness of about 75 feet. The estimated yield of a horizontal collector well at the site was calculated using the following equation (Hantush and Papadopulos) and assumptions. where: Sc, Q K b r a l Scs 2: ['r c.:J2 ( _iL) Ln 2(1 -27lKb ,,e cos 7t (2-. b .._, -= Drawdown in collector well, ft -Yield of collector, gpd = Hydraulic Conductivity, gpd/fe """"'Saturated thickness of aquifer, ft = (2 (a-rc))/1 = Effective distance to a line of recharge, ft =Average length oflatera1s, ft = Radius of co Hector caisson, ft _; (2a -rc-1)/1 = Effective radius of each lateral, ft =Depth uflaleral below stalic water level, fl b 4i rw)) Using site-specific information and a variation of the above equation, the yields of a collector well at the test site was calculated using the following assumptions: Top of Aquifer Elevation Base of Aquifer Centerline of Laterals Tnside Diameter of Caisson Static Water Level (test, low conditions) Transmissivity Hydraulic Conductivity Radius ofLaterals Design distance to line source of recharge Average Lateral Length No. ofLatcrals 25 feet below grade 100 feet below grade 92 feet below grade 20 feet 20 feet below grade 450,000 gpd/ft (57 oF) 6,000 gpdltt2 (57 ° F) 0.5 ft 1000 fl (test conditions) 1200 ft ("'inter, low) 900FT (summer, low) 200ft 14 Calculated yields lUlder three conditions (Test; Low, Winter-45 n F and Summer, Low-65 ° F) are shown in Figme 1 (attached).
