n} — <br /> z - <br /> PENN <br /> s ` <br /> MIN. <br /> _ - --a <br /> =o <br /> a <br /> f <br /> Quarterly Ground--Water Monitoring January 31, 1989 <br /> '�. Beacon Station No. 3-492, Manteca, California AGS 86102-3 <br /> for each respective contar,inant in drinking water, as recommended <br /> by the California Department of health Services. Samples from <br /> well MW-1, which contained floating product, weire not collected <br /> or analyzed. <br /> Because free product was observed in monitoring well MW-1, <br /> Applied GeoSystems recommends that subjective analyses of water <br /> from the wells be performed on a monthly basis. As an interim <br /> remedial response, free product should be removed by bailing and <br /> stored onsite in drums until the next sampling event. At that <br /> time, the product should be removed with the purge water. We <br /> also recommend thet Beacon Ail company a-.tempt to evaluate the <br /> source of the free product, If free product continues to be <br /> present in the monitoring wells, delineation and active <br /> mttigation '.uay be necessary. <br /> Copies of this report should be fe -war,]ed to Ms. Laurie Cotulla <br /> of the San Joaquin County Local Health District, Environmental <br /> Health Division, 1601 Hazelton Avenue, P.O. Box 2009, Stockton, <br /> California 95201, and Mr. Gordon Lee Boggs of the California <br /> Regional Water Quality Control Board, Central Valley Region, 3443 <br /> Routier. Road, Sacramento, California `15827-3098. We have <br /> tentatively scheduled the next sampling event for the week of <br /> December 5, .1588.
