Are all groundwater Field Parameters X <br /> (Sept 93/Aug 97) Monitoring Parameter, and COCs <br /> (if required) sampled and analyzed? <br /> in. Have any groundwater concentration X <br /> MW-3 with trace VOCs <br /> limits been exceeded? If yes,identify (Trichloroethene and 1,1 <br /> in comments. Dichloroethene). MW-2 with <br /> trace Acetone and Naphthalene. <br /> n. Is there a description and graphical X <br /> presentation of groundwater flow <br /> direction and gradient? <br /> o. Monitoring Wells: Is there a ' X <br /> description,method, and time <br /> of water level measurement and <br /> well recovery time? <br /> p. Purging: Is there a description X Ensure that field parameters are <br /> of the purging method,purge stabilized during the purge. <br /> pump and its placement, and <br /> field parameters? <br /> Additional Comments and Recommendations: <br /> VOCs (TCE and 1,1 DCE) detected in MW-3 at trace levels. <br /> Trace acetone detected in MW-2. The County does not want to retest since acetone is a common solvent. <br /> Acetone was detected in the field blank. <br /> Naphthalene was detected at a trace concentration in MW-2. The County did not order a retest because it <br /> was the only VOC detected in the well but is not a common laboratory contaminant. <br /> The County should retest MW-2 for VOCs if Naphthalene is detected in the fourth quarter Monitoring <br /> Report. <br /> Possible LFG odors from V;W noted. <br /> Ensure that field parameters are stabilized during the well purge. <br /> RWQCB Staff Signature: 14 o <br /> Date: <br />
