3.0 FINDINGS <br /> It <br /> 3.9 Groundwater Level Measurements <br /> As measured on 22 December 1999, groundwater was present at a depth of 29 92 ft btc (below <br /> top of casing) in MW-1 and at a depth of 30 40 ft btc in N1W-3 On 27 January 2000, the <br /> groundwater level in the two (2) groundwater momtonng wells were again measured by EI The <br />' <br /> groundwater was present at a depth of 28 70 btc in MW-1 and at a depth of 28 60 btcs in MW-3 <br />` This limited data indicates a southerly flow at a gradient of 0 01 ft/ft on 22 December 1999 The <br /> gradient dropped to 0 0036 ft/ft on 27 January 2000 <br /> The groundwater was again measured on 20 April 2000 and found to be at a depth of 25 62, <br /> 25 99 and 25 55 feet below top of casing (btc) (MW-1, MW-2 and MW-3 respectively) The <br /> groundwater direction of flow was calculated to be southeast at a gradient of 0 0027 ft/ft <br /> The water level has risen significantly in the past quarter and the gradient has been dropping <br />' Table 1.
