1 <br /> 82 Groundwater <br /> Groundwater was initially encountered at a depth of approximately $0 feet in MW-5 and 75 feet <br />' in MW-6 during drilling The groundwater ascended to a depth of approximately 70 feet as <br /> measured inside the hollow-stem auger during drilling <br />' Based upon the groundwater elevations as measured (December 27, 1993) in wells MW-4, MW-5 <br /> and MW-6, the groundwater flow is generally to the west The groundwater has a calculated <br /> hydraulic gradient of 0 0015 ft/ft The groundwater monitoring well MW-6 is located in a <br /> general down-gradient direction of the former tank locations Groundwater elevation contours <br /> are presented on Figure 13, Groundwater Elevation Contour Map The groundwater elevation <br /> as measured in well MW-4 has risen by 7 04 feet since the previous measurement made on <br /> August S, 1993 A summary of the groundwater elevation for MW-4 is presented on Figure 14. <br />' 9.0 LIMITATIONS <br /> The findings presented in this report are based on field data and observations and from a limited <br /> analytical testing program This report has been prepared in accordance with generally accepted <br /> methodologies and standards of practice in the area No other warranty, expressed or implied, <br /> is made as to the findings included in the report <br />' The findings of this report are valid as of the present The passage of time, natural processes or <br /> human intervention on the property or an adjacent property may cause changed conditions which <br /> can invalidate the findings presented in this report <br /> 1 <br /> 1 <br /> I <br /> I <br /> 5 <br /> I &Associates <br />
