CONCLUSIONS AND REC01#flEU ENDATIONS <br /> The petroleum hydrocarbon and MTBE concentrations in groundwater samples collected from <br /> the shallow wells this quarter are within the historical norm for this site Wells MW-5 and <br /> i <br /> RW-1A continue to contain the highest levels of hydrocarbons and MTBE Analytical data from <br /> offsite wells suggests the hydrocarbons and MTBE detected in onsite wells are remaining onsite <br /> Cambria recommends continued monitoring and sampling of site monitoring wells to evaluate <br /> concentration trends now that a groundwater extraction system is in operation, full time, at the <br /> site <br /> • <br /> 0783 2 <br />
