„ Mr Michael Infurna <br />�. Page 3 <br /> RECOMMENDATIONS <br /> Groundwater flow at the site appears to periodically reverse between the directions of northwest and <br /> southeast Contaminant concentrations m well MW3, installed wnthm the former tankpit, have shown <br /> no clear trend of increase or reduction It may be necessary to install additional monitoring wells in <br /> order to delineate the downgradient extent of contamination Because of the periodic flow reversals, <br /> one well would need to be installed to the northwest of the former tankpit and another to the southeast <br /> If so directed, we will submit a workplan to mstall additional groundwater monitoring wells Should <br /> additional wells be installed it may be appropriate to reduce the sampling frequency of cross-gradient <br /> wells NMI and MW2 <br /> The next round of groundwater sampling is scheduled for February 2000 You will be provided with a <br /> miumum of 48 hours notice prior to conducting fieldwork If you have any questions or comments please <br /> contact Ground Zero at your convenience <br /> Respectfully, <br /> Gro ero AnaiysInc <br /> Sean Garvey, ��� <br /> Epi0. <br /> Staff lognst <br /> GREGORY P. <br /> 4 STAN. <br /> Gregory P Stahl,RG 5023 No. 5023 <br /> CA Certified Hydrogeologtst No 254 ,rX <br /> qTE AL <br /> Attachments OF CIF�Q� <br /> cc Mr Norm Crum,Woolsey Oil,Inc <br /> Ms Karen Collins,Environmental Closures,Inc <br /> Mr Marty Hartzell,RWQCB <br /> Mr Richard McPherson,Property Owner <br /> —bley chtlgmr14gm20D0 doc <br />
