Advanced <br /> GeoEnvironmental, Inc. - <br /> qf Northern California <br /> 15 February 1996 <br /> AGE-NC Project No. 96-0203 <br /> Ms. Mary Meays <br /> SAN JOAQUIN COUNTY PHS-END <br /> P. O. Box 388 <br /> Stockton, CA 95201 <br /> Subject: Work Plan for Well Abandonment/Destruction <br /> PDM Strocal, Inc. <br /> 2324 Navy Drive, Stockton, California <br /> Dear Ms. Meays: <br /> At the request of Mr. Gordon McCord of PDM Strocal, Inc., Advanced GeoEnvironmental, Inc. <br /> (AGE) prepared this Work Plan for the Abandonment/Destruction of the ground water monitoring <br /> wells at the referenced site. <br /> In accordance with the San Joaquin County Public Health Service - Environmental Health Division <br /> (FHS-EHD) requirements, the monitoring wells at 2324 Navy Drive must be properly abandoned to <br /> obtain conditional site closure. The location of the site is illustrated in Figure 1 -Location Map. <br /> Two 2-inch diameter ground water monitoring wells(MSV-1 and MW-2) are currently Iocated on the <br /> property. According to a representative of PDM, each well is approximately 15 feet in depth. <br /> Monitoring well locations are illustrated on Figure 2 - Sire Plan. <br /> In preparation for abandonment, each well cover box or monument cover will be removed. Each well <br /> will be filled with grout and a pressure will be applied to each well for approximately five minutes to <br /> ensure grout penetration into the filter pack. After the filter pack has been penetrated, each well will <br /> be approximately three feet below surface grade with grout. Finally, the upper three feet of the wells <br /> will be over drilled and filled to the surface with grout. <br /> In order not to conflict with the site operations, PDM Strocal, Inc. has requested that the <br /> abandonment/destruction procedures be conducted on a Saturday. We would like to schedule the <br /> procedures for Saturday, 24 February 1996.. <br /> 1803 West March Lane, Suite A,Stockton,California 95207 <br /> Telephone(209)956-0264 FAX(209)956-0700 <br />
