RECOMMENDATIONS,' <br />' Based upon data collected,fromi'the site,-AGE recommends continued quarterly monitorin of the <br /> site; the,next:monitoring event is scheduled for September 2000.

Evaluations of the <br /> geologic/hydrogeologic coiiditions,at"the site for the pil p' se of this-investigation`are made from a <br /> limited number of available`data'points (i.e. gzound water and/or soil samples) and subsurface <br /> conditions may vary away,froin these data points.No other warranty, expressed or implied,•is made <br /> as to the professional recommendations contained in this report. <br /> !t •'r ' 1.. ; I i Advanced GeoEnvironmental,[nc..
