The updated site map <br /> depicts the groundwater flow direction to be to the north-northwest (refer to Site Plan, Figure 3). <br /> The present groundwater flow direction is also indicated on the updated Figure 2, Site and <br /> Adjacent Properties Schematic Plot Plan. <br /> As the groundwater flow direction was originally estimated to be generally north, the updated <br /> information does not change the conclusions and recommendations of the above referenced original <br /> report. <br /> It has been our pleasure to be of service to ARCO Products Company.
