The number of SVE wells installed for <br /> feasibility testing must be limited. Remediation of the deeper saturated zone <br /> y may require additional methods such as air sparging. <br /> EHD concurs with this approach butfrecommendg.thatFaa– onitoring kwell,with_'a <br /> short-scr eenedlintervalit5e�laced�t ea'�`c-hTzo e h re e CPTr1 data�..has indicatedf <br /> petroleum was detecte'd!before the additiorial.CP,-Ttworkibe enacted.
