RECOMMENDATIONS <br /> I <br /> Based upon the data collected to date, AGE recommends - <br /> _ Installation of two additional "deep aquifer zone" ground water monitoring wells F <br /> • Preparations for implementation of the approved Corrective Action Plan Additional soil <br /> vapor extraction and in-situ air sparging wells should be installed at the site <br /> • Continued quarterly monitoring, the next quarterly ground water sampling and monitoring <br /> 1 event should be scheduled for late December 1999 <br /> 6.0. LIMITATIONS <br /> 1 Our professional services were performed using that degree of care and skill ordinarily exercised by <br /> environmental consultants practicing in this or similar localities The findings were based upon, <br /> analytical results provided by an independent laboratory Evaluations of the geologic/hydrogeologic <br /> conditions at the site for the purpose of this investigation were made from a limited number of data, <br /> points (i e m6mtonng-well ground water samples) and subsurface conditions may'vary away from <br />' these data points No other warranty, expressed or Iinplred, is made as to the professional <br /> recommendations contained in thls'report <br /> i <br /> A <br /> I � I <br /> i = i <br /> s <br /> I , 4 <br /> G <br /> Y <br /> f <br /> r <br /> 1 4 <br /> Advanced GeoEnvirpnmental,Inc <br /> s <br /> i f e <br /> i = <br />
