it <br /> HISTORY <br /> On November 14 , 1989 three tanks were removed at this site and three fiberglass tanks were <br /> installed . The laboratory results taken at the time of removal tested positive for gasoline <br /> hydrocarbon contamination . <br /> On December 19, 1989 an Electromagnetic Induction Survey was conducted on the site to aid the <br /> investigation of the aerial extent of the contaminated soil and in planning the position of the <br /> monitoring wells. <br /> In January 1990 three monitoring wells were installed . They were reported in our report dated <br /> February 9, 1990. <br /> In March and April 1992 , three more monitoring wells were installed , They were necessary <br /> because the groundwater had fallen below the depth of the original wells. This work was reported <br /> in our report dated April 30 , 1992 . <br /> In July 1993 we installed two additional monitoring wells and drilled one boring. This work was <br /> reported in our report dated August 24, 1993. <br /> In September 1994, we installed three additional monitoring wells. This work was reported in our <br /> report dated October 10, 1994. <br /> In April 1995 we drilled two CPT borings and they were reported in our report dated March 15, <br /> 1995, <br /> In February and March , 1996 five vapor extraction wells , one air sparging well and one boring <br /> were installed at this site. This work was reported in our report dated March 19, 1996. <br /> In April 1996 we drilled two additional CPT borings. They were reported in our report dated June <br /> 10, 1996. <br /> In July 1999, we drilled an additional monitoring well MW- 12 to 80 feet. This was reported in our <br /> report dated August 5, 1999 . <br /> On November 6, 2000 we drilled two borings (13-2 and B-3) to a depth of 90 Feet Bgs and 100 <br /> Feet Bgs. This was reported on our report dated December 14, 2000. <br /> On November 17, 2003, we submitted a Amended Site Concept Model . <br /> On July 20, 2005, we drilled one boring and two monitoring well (B4, MWA4 and MW-16) to a <br /> depth of 158 feet bgs for the borings and 50 feet bgs for the two monitoring wells. <br /> This was reported in the drilling report dated August 24, 2005. <br /> 2 <br />
