2 . Page 7-2 , Section 7-5 <br /> The EPA concurs with the report's recommendation that Well 4 <br /> be abandoned. Groundwater sampling from this well gives <br /> inconclusive results because the well is screened in both <br /> the Upper and Lower Tulare. This well could become a <br /> pathway for cross-contamination for the same reason. Prior <br /> to any well abandonment, it is recommended that a video log <br /> be performed to verify the perforated interval of this well. <br /> If it is determined that Well 4 is perforated only in the <br /> Lower Tulare, its value as a monitoring well could be <br /> reassessed. <br /> REFERENCES: <br /> 1.
