Mr Johnson <br /> Page 3 <br /> Each hole was checked for total depth prior to grouting to ensure it had not caved <br /> substantially, as required by PHS/EHD The open holes were then grouted using the <br /> tremmie method Grout materials consisted of neat cement and/or volclay well grout <br /> The volclay was used in the upper 20 feet of seal for wells in the tank pit area This <br /> material was used so that future excavation in the area would not damage the well seal <br /> (volclay is a soft bentonite that will not crack when disturbed) All abandonment <br /> procedures were performed under the direction of PHS/EHD inspector Mike Infurna The <br /> permits for well abandonment are included as Appendix B <br /> This report summarizes the well abandonment project performed at Thrifty Service Station <br /> 172 Should you have any questions regarding the contents of this report, please feel free <br /> to call me at 310-799-0084 <br /> Sincerely, ___ ° <br /> MMA. <br /> NWOUICH <br />.
