ATTACHMENT I:FORMATION TESTING PROGRAM <br /> As to the present rate of lateral movement of these shallow ground waters and deep <br /> formation waters, there are no available measurements. However,it is known that the <br /> changes in groundwater elevation over this area are very gradual,typically less than 5 feet <br /> over a lateral distance of 1 mile. Also, the structural dip of the deep formations is known to <br /> be less than 2 degrees in this area. These very gentle gradients suggest that the rate of lateral <br /> movement of both the shallow and deep waters in this area is insignificant. <br /> Direction and Rate of Injected Fluid Migration <br /> The direction of injectate fluid migration will be essentially radial from the proposed <br /> injection well,as any existing lateral variations in the local hydraulic gradient within the <br /> Domengine will be dominated by that injection. The estimated rate of expansion of the <br /> injectate front radially outward from the well,assuming a continuous injection rate of <br /> 200 gpm into an exposed interval of 230 feet of sand having 35 percent porosity,will <br /> average 71 ft/yr for the first 10 years,and will be reduced to 25/ft per year by the end of the <br /> 20th year. The location of that injectate front at the end of 20 years is calculated to be at an <br /> average radial distance of 1,008 feet from the well. <br /> SACI3713221082550025(ATTACH MENT-I.DOC) 1-7 <br />
