RECOMMENDATIONS <br /> tBased on this and previous site investigations, AGE recommends <br /> • Continued quarterly momtonng'of the well network The next monitoring event took place <br />' in December 2003 , <br /> • Conduct additional contaminant assessment east of the current monitoring well network, <br /> 10utilizing grab ground water sampling for potential monitoring well placement ' <br /> I <br /> IF r <br />' 6.0. LIMITATIONS <br /> 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 Evaluation of the geologiclhydrogeologic <br /> conditions at the site for the purpose of this investigation was made from a limited number of <br /> available data points(soil and ground water samples)and subsurface conditions may vary away from <br /> these data points No other, warranty, expressed or implied, is made as to the professional, <br /> interpretations, opmidAs and recommendations contained in this report ' <br /> I <br /> I 1 <br /> I I <br /> 1 <br /> 1 <br /> 1 y I i 4 1 tl <br /> ' I <br /> I <br /> Advanced Geo Environmental,Inc <br /> 1 ry I 9 <br /> , 4 <br /> ' � w <br /> r Y � <br /> I 1 <br /> 1 _ — <br />
