This could not be verified during the latest <br /> round because four of the five wells were dry. The water level elevations and gradient for <br /> the April 27, 2007 data are shown on Figure 1. <br /> In each sampling round the volume of water in each well was calculated based on the <br /> water level measurements and 3 times this volume was purged from the wells using a 12- <br /> volt purging pump. PH, EC, and temperature were measured during purging. <br /> Measurements recorded in the field are shown in Table 2. <br /> Table 2.
