The destruction of <br /> nine monitoring wells at the site has been tentatively scheduled. <br /> The wells will be destroyed by pressure-grouting, in accordance with San Joaquin County <br /> Environmental Health Department (SJCEHD) requirements. Destruction of the wells will include <br /> filling each well with grout;application of pressure(15-20 psi)to ensure grout penetration into the <br /> filter pack; removal of each well cover box; and over-drilling to a depth of approximately 3 feet <br /> below surface grade(bsg). The top three feet will be backfilled with neat cement.The grout mixture <br /> will consist of Type 1/II portland neat cement and not more than 6 gallons of water per 94-pound <br /> sack of cement. Once the wells have been destroyed, AGE will prepare a well destruction <br /> confirmation letter for submittal to the SJCEHD. <br /> Once the wells have been properly destroyed and the receptor survey completed,we do not anticpate <br /> any additional work will be required for the site.
