The number of SVE wells installed for <br /> feasibility testing must be limited. Remediation of the deeper saturated zone <br /> may require additional methods such as air sparging. <br /> EHD concurs with this approach but recofnmends,thatra'niortitoring wellwith a°- <br /> �� ,._ - <br /> short-,scr eenedimterval beTplacedrat"each zone wh e CPT 1 data�hasYindicatedl <br /> ire leum,was detectedIefv e the additionaI.CPT�work'lbe enacted.
