Michael and Sharon Divarez - 3 - *me October 24, 2011 <br /> Site History/Assessments <br /> In November 1992, soil contamination was identified during the removal of USTs. To date, 15 <br /> monitoring wells have been installed and monitored regularly. A Site map showing the location <br /> of the former (fST$, rr.0rj*t0ring wells and the groundwater gradient and hydrocarbon contours is <br /> provided at the end of this five year summary. <br /> Remediation Summary <br /> • Free Product: No free product was documented throughout the life of this case <br /> • Soil Excavation- Unknown <br /> • In-Situ Soil Remediation: None conducted <br /> • Groundwater Remediation. Groundwater extraction, conducted from June 2004 'through <br /> February 2009 removed approximately 2.255 pounds of TPHg and 3,1371,500 gallons of <br /> groundwater <br /> General Site Conditions <br /> • Geology and Hydrogeology., The Site is underlain by interbedded and intermixed sand, <br /> silt and clay, The depth to groundwater at approximately 27 feet bgs and the <br /> gTOUndwater gradient is northeast at approximately 0 004 feet/foot, <br /> • G-oundvvater Trends.
