The <br /> leading edge and extent of these components can not be <br /> determined at this time. However, it does appear that <br /> migration towards the southeast has not occurred. Additional <br /> wells south, southwest, and west of the excavation would <br /> provide more information to ascertain the nature of the <br /> ground water conditions necessary for developing any remedial <br /> measure deemed necessary by the regulatory agencies. <br /> VXXX. RECO MF".LTTONS <br /> Based on our findings we recommend the following additional <br /> tasks: <br /> • The tank excavation and the backhoe test pits should be <br /> covered with an asphalt patch to prevent rain and surface <br /> water infiltration into the soil. <br /> a The local shallow ground water gradient beneath the tank <br /> ----'-- -- - - ---- - excavation has been determined from .the four shallow ---- -- - — <br /> ` ground water monitoring wells. <br />
