Knowles Gas station <br /> 202/799-5027.02 <br /> ra July 21, 1988 <br /> t <br /> ; 1F feet in MW-1, MW-2 and MW-3, respectively. This data indicates <br /> an estimated groundwater flow direction to the southeast under a <br /> ` relatively flat gradient of less than 1 percent (see Figure 3, <br /> f <br /> Piezometric Surface Map) . Due to the relatively flat nature of <br /> the ;groundwater gradient at the site, <br /> 1-i it presumed to be <br /> localized and subject to variation. <br /> s � <br /> i <br /> WATER USAGE <br /> The locations of approximately 30 nearby domestic and <br /> irrigation wells are shown on the Well Location Map (Figure 4) . <br /> �f <br /> The well locations were,.determined from the Lincoln Village Area <br /> Well.
