i <br /> INTRODUCTION <br /> This site has been a LUFT site since January 26, 1990. On November 14, 1989 three <br /> underground gasoline tanks were removed . Soil samples of the dirt around the tank pit were <br /> found to be contaminated with gasoline. <br /> The contaminated water was found to be flowing to the northeast. The contaminated plume has <br /> moved to the northeast. Wells have been drilled over the property and northeast and east of the <br /> property. The most easterly well is MW-11 , which is located on Aurora Street one block east of <br /> Grant Street. Well MW-9 was placed on the Sun Gardens property. Three borings were placed <br /> on the on Beneto, Inc. property and two hydropunch borings were placed on the Sun Gardens <br /> property, to the west of this site. <br /> B. SITE 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 (MWA , MW-2 and MW-3) were installed . They were <br /> reported in our report dated February 9, 1990. <br /> In March and April 1992 , three more monitoring wells (MW-4, MW-5 and MW-6) were installed . <br /> They were necessary because the groundwater had fallen below the depth of the original wells . <br /> This work was reported in our report dated April 30, 1992. <br /> In July 1993 we installed two additional monitoring wells (MW-7 and MW-8) and drilled one boring <br /> (B- 1 ). This work was reported in our report dated August 24, 1993, <br /> In September 1994, we installed three additional monitoring wells (MW-9, MWA0 and MW-11 ) . <br /> This work was reported in our report dated October 10, 1994. <br /> On June 19, 1995 we drilled two hydropunch borings (HP- 1 and HP-2) they were reported in our <br /> Activity Report dated June 30, 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 (HP-3 and HP-5) . They were reported in our <br /> report dated June 10, 1996. <br /> 3 <br />
