5.0 FURTHER ASSESSMENT <br /> Additional assessment of the extent of groundwater contamination is being planned. Property <br /> owners along Country Club Boulevard have been contacted to obtain access for further drilling, and <br /> two owners have agreed to allow drilling on their properties. Upgradient is currently in the process <br /> of preparing permits to drill on these properties and in the public sidewalk. When encroachment <br /> permits from the County have been approved, they will be forwarded to EHD for final approval. <br /> Drilling is anticipated to take place in mid-December, in conjunction with fourth quarter <br /> groundwater monitoring. <br /> 6.0 CONCLUSIONS AND RECOMMENDATIONS <br /> The main conclusion to be drawn from third-quarter monitoring data is that the direction of <br /> groundwater flow varies widely at this site in response to unknown controls. Because of the <br /> fluctuation in flow direction, the geometry of the groundwater plume is difficult to predict at this <br /> stage of the investigation. We recommend better coordination with the consultant that is :monitoring <br /> the wells at the former Chevron site on the west side of Franklin Street in order to develop a clearer <br /> picture of the groundwater gradient and contaminant plume. <br />• <br /> 4 <br />
