>K" <br /> Nove:Tber 11, 1987 <br /> Ms. Lori Cotulla and Mr. Dan Moe <br /> San Joaquin County Health District <br /> 1601 E. Hazelton Avenue <br /> Stockton, Ca 95201 <br /> RE: GRMCF.-,�7 ASSESS!,a:NT OF PROPERTY LMUED AT 724 E. GR-kN'T L= <br /> ROAD, TP-)kC`Y, CA <br /> Dear Ms. Cotulla md Mr. Mce: <br /> It is my understanding that your agency nay be requiring Reynolds <br /> Brawn to install several aroundwater manitoring ,�lls at the prcpexty <br /> in order to define the extent of benzene contaidnation in the acmifer. <br /> The request made by Mr. Moe is based on the results of a report by <br /> Appliea Geosystems indicatLng the presence of benzene in standing <br /> groundwater upon removal of an underground tank at the subject <br /> prcperty- Following your suggestion, we followed the advice of our <br /> con-sultants, A(Tua Terra Technologies, Inc. They su=ested resa-7�pling <br /> the ey-istinq monitorina well because the crroumt,;ater samle collected <br /> by Applied G—e-systems was not taken accor=g to protocol established <br /> bv the Deoartment of Health Services or the Recional Water Quality <br /> Control Board for collecting of groun(t.;ater. The results of resa-7pling <br /> the existino 7tr)nitorina w-ell indicated that benzene w--s not- detectable- <br /> I am of the opinion that anz)rooriate m--asures �,7-=re take-i to determine <br /> '�h �he folla.�ing findings state otherwise: <br /> if conta:rdnation exists, whi <br /> 1. Soil samples analyzed by Applied Geosyste.ms indicated no <br /> conta-aination. <br /> 7 <br /> 2. The d---em gra(Lent well, installed and sa-rmled by Re-r-inedy, Jenks <br /> Chilton, indicated no detectable levels of benzene. (Report dated <br /> January, 1987.) <br /> 3. Keiinedy, Jenks & Chilton found no detectable levels of benzene in <br /> soil saimles and 13 50 43 mg/Kg (ppb) of toluene in soil. <br /> 4. The resampling of the existing for benzene, xylene and <br /> toluene by Aqua Terra Technologies, indicated no de--tectable levels <br /> I <br /> of these ca-->:)-unds. <br /> 5. The sampling of the around,.,:ater by Appl4ed Geosystems was <br /> inappropriate and not accorcang to protor-ol. <br /> ov-ens <br />
