Entrained Ground Water Collection and Disposal. <br /> Due to high moisture content, especially during rainy days, extracted soil vapor carries ground <br /> water droplets which are separated from the soil gas in the knockout pot. Currently, separated <br /> groundwater is transferred automatically to 55-gallon drums. It has been requested that a ' <br /> secondary container to the 55-gallon drum be installed to prevent overflow, or a larger collection <br /> tank installed, assuring that no overflow will take place between the weekly site visit by a <br /> technician. <br /> Wards will install a 500-gallon poly tank for collection of ground water transferred from the <br /> knockout pot. This volume will be sufficient for at least two weeks of continuous operatior of the <br /> remediation system. The effluent contained in the tank will be removed, manifested and preperly <br /> handled. <br /> 2. Grouting Sump Bottoms. <br /> The remediation well sumps are covered with gravel. To prevent infiltration of any produci s into <br /> the soil, the bottom of the sumps must be grouted. <br /> As requested, the bottom of the sumps will be grouted. <br /> PLANNING,ENVIRONMENTAL ANALYSES AND <br /> HAZARDOUS SUBSTANCES MANAGEMENT AND REMEDIATION <br />
