During purging; GR personnel will attempt to collect <br /> depth to water (DTW) readings from the wells in use. In addition, DTW readings will be <br /> collected from the monitoring wells in the vicinity of the purged well. ,DTW readings will be <br /> collected continuously, beginning prior to initiation- of groundwater purging until <br /> groundwater levels have -recovered sufficiently following _completion cf.purging. The <br /> observed drawdown in the purging well and observation wells will be utilized to form a ` <br /> qualitative estimate of the influence around the purged well., The results of the performance <br /> test will be presented in the first status report.'.` r: <br /> If you have any questions regarding this.report, please.feel freeto call either of us in our <br /> Dublin office at (925) 55;1-7555 k = <br />` Sincerely, . . . ,; `. r +• ; <br /> Gettler-Ryan Inca <br /> W.
