If the <br /> capture radii for the wells is shown to converge, then no <br />! new wells will need to be added. <br /> The project commenced with the application of a vacuum to <br /> the existing wells. A capture radius greater than 30 feet <br /> was observed for the vapor recovery wells. No access was <br /> gained to the monitoring wells to measure capture radius. <br /> The total volatile hydrocarbons were measured in each well <br /> using an instrument equipped with a Flame Ionization <br /> Detector, with results as follows: <br />
