I <br /> Mr Bill Little <br /> Advanced GeoEnviron mental (North) <br /> LELAND Property <br />' December 29, 1997 <br /> Page 2 <br /> 1 <br />' COMMENT <br /> The data from these analyses indicate that, although only low levels of viable microorganisms <br /> were recovered from both wells, sampling point VW-1 contains a high proportion of gasoline <br /> biodegrading microbial subpopulation It was noted however, that sampling point MW-5 <br />' contained ND levels of biodegrading cells Neither point contained high levels of general <br /> heterotrophic cells, likely due to the presence of less than optimal physicochemical conditions, <br /> particularly with respect to available nitrogen concentrations Whale waters associated with <br />' sampling point VW-1 can be expected to undergo a limited degree of biologically-based <br /> contaminant attenuation, neither well will attain significant bioaatenuation activity unless and <br /> until physicochemical conditions are improved Based on these data therefore, it is anticipated <br /> that the reduction of contaminant over time due to bicattenuation processes will be minimal <br /> only <br /> Should you have any questions concerning this information, please do not hesitate to contact <br />' me <br /> 1 <br /> AKK ch <br />
