Lincoln <br /> Village Properties has taken ownership of the three existing upgraded underground storage tanks <br /> (USTs) Lincoln Village Properties is leasing the site to Prestige Oil who will operate the site as a <br /> gasoline service station Currently the site is being remodeled and upgraded <br /> Thirteen groundwater monitor wells are associated with this site.

Sample point SB8 is down gradient of MW12 approximately 180 feet <br /> east of MW12 within the northern curb area of Douglas Road Water samples will be obtained <br /> from the 1'and 2°d water zones, Zones A and B as noted in the Levine-Fricke-Recon May 22, 1998 <br /> report titled "Internum. Source Area Remedial Investigation Report" Based on slug test data and <br /> groundwater gradient information this sample point should provide degradation information and be <br /> at the leading edge of the TPHg, BTEX plume <br /> 3 R-603 extent WP 2-2001 <br />
