Ms. Diane Hinson <br /> March 4, 1991 <br /> page two <br /> 2. Make necessary repairs to all groundwater monitoring wells which <br /> are salvageable. All vadose zone wells originally installed by <br /> Kleinfelder, and all monitoring wells found to be unsalvageable <br /> will be properly destroyed after applicable permits are obtained. <br /> It is understood that at least two of the monitoring wells (MW-4 <br /> and MW-5 ) were buried underneath the recently constructed office <br /> building. Furthermore, monitoring wells MW-1 and MW-7 were <br /> properly abandoned and destroyed during the soil remediation <br /> activities conducted from 9/88 - 12/88. <br /> 3. Conduct a detailed review of available records concerning other <br /> environmental investigations (past or present) in the general <br /> area. This information will assist us in determining the <br /> placement of monitoring wells to delineate the extent of <br /> groundwater contamination, if deemed necessary. <br /> 4. Prepare a technical report summarizing the activities mentioned <br /> above. The report will present both gradient information and <br /> analytical results obtained from accessible monitoring wells, <br /> assess file information as it relates to this site, and make <br /> recommendations for any further work, if deemed necessary. <br /> PHASE II <br /> 1 . Phase II will consist of actions necessary to comply with the <br /> recommendations presented in the Phase I technical report, as <br /> agreed to with the appropriate regulatory agencies. <br /> The first step in this process will be obtaining access to the <br /> property from the current property owner (i.e. Stone Bros. ) . I would <br /> anticipate the report being completed within 4-6 weeks from the date <br /> that formal access is received. If any unexpected difficulties <br /> arise, I will notify your department immediately. <br /> I trust this letter accurately summarizes the items agreed to in our <br /> meeting. If there are any questions or comments, please feel free to <br /> call me @ (415 ) 277-2303. <br /> Sincerely, <br /> Ronald E. Bock <br /> Environmental Engineer <br /> attachment <br /> cc : J. E.
