� • Sailors World, Inc. <br /> Summit Project No. 922030 <br /> October 5, 1995 <br />� Page 9 <br />� petroleum hydrocarbons appear to be relative low. Risk to wells,basements, and utilities appears <br /> to be minimal based on groundwater observations and on removal of the source area. <br />� Results of chemical analysis performed for probe locations on the west side of Highway 15 <br /> indicate-the presence of unidentified components with moleculaz weights higher than gasoline. <br />� Based on the observed groundwater flow characteristics and site history, it appears that these <br /> impacts did not originate at the Sailors World site and are likely a result of previous activities <br /> that may have occurred in the area of the former service station located to the southwest of the <br />� site. <br /> Considering that corrective action activities completed at the site included removal of 130 cubic <br />� yazds of petroleum hydrocarbon impacted soil and that the size of the site is relatively small, <br /> these conective actions appear to have effectively reduced the risks of petroleum hydrocarbons <br /> that may affect Lake Minnetonka. Based on results of chemical analysis of groundwater and soil <br />� samples, the location of identified receptors, and the removal of the source azea, the risk to the <br /> other identified potential receptors appears to be relatively low. <br />'� 5.0 RECOMMENDATIONS � <br />� Based on the data collected and reviewed as a part of this assessment, it is our opinion that <br /> additional assessment or corrective actions do not appear to be warranted at this time. <br />� <br /> 6.0 REFERENCES <br />� Balaban, N.H. ed., 1989.
