Discussion <br /> Six new groundwater monitoring wells were installed and sampled A relatively moderate to <br /> slow groundwater movement is inferred from the groundwater measurement data Overall site <br /> shallow groundwater movement is north-northeasterly and the flow direction is consistent with <br /> historically observed trends Concentrations of TPHG were observed in the Wells MW-2, MW- <br /> 3, <br /> W- <br /> 3, MW-6 and MW-9 and contaminants were not observed in MW-1 In our opinion, these <br /> represent highly degraded fuel and fluctuating concentrations of contaminants will continue to <br /> show an overall declining trend <br /> Monitoring Schedule <br /> The continuation of the quarterly groundwater monitoring program is recommended for this <br /> site It is our understanding that the San Joaquin Valley RWQCB has requested that monitoring <br /> include all oxygenate compounds to be analyzed by EPA Method 8264 Wright will schedule the <br /> addition of these compounds in the next sampling round <br /> Limitations <br /> This report has been prepared specifically for the Mr Ed's Muffler Site at 595 E 11th Street <br /> in Tracy, and was done according to the current State and local agency suggested guidance <br /> documents for these investigations The interpretations, conclusions and recommendations made <br /> herein are based on the data and analysis for the soil and water samples collected on-site and <br /> should be reviewed in the context of this report and other site reports Please note that reports <br /> of contamination must be submitted to the agencies in a timely manner Wright Environmental <br /> Services, Inc is not responsible for errors in laboratory analysis and reporting, nor for <br /> information not available during the course of the study, and no warranty or guarantee is <br /> expressed or implied therein <br /> If you have any questions concerning this report, please call �kF'Q GFO <br /> S�QeKER Af <br /> Sincerely, <br /> Wright Environmental Services, Inc t W 1262 <br /> CERTIFIED <br /> f ENGINEERING <br /> u, GEOLOGIST <br /> hn so Affons <br /> Project Ma ager Ch EsGp1262, HG246 OF CAUf���`P <br /> Attachments Figure 1 Site Plan and Groundwater Elevation Contour Map <br /> Groundwater Sampling Information Sheets <br /> Chemical Analytical Date and Chain-of-Custody Form <br /> Page 4 <br />
