October 4, 1999 <br /> } <br />' 2 Further lateral investigation should be conducted at the site Due to access Iimitations <br /> from neighboring houses, city sidewalks and busy city streets, it is recommended that a <br /> less invasive approach be taken in order to obtain data regarding the lateral limits of the <br /> plume Several possibilities exist, including passive soil gas survey equipment and <br />' direct-push equipment such as a GeoProbe These two technologies require small <br /> diameter holes and would involve less time obstructing traffic or neighboring properties <br /> These approaches could be used to obtain information as to where the limits of the plume <br />' maybe, then wells could be installed <br /> 3 A licensed surveyor should prepare a scaled map of the site and neighboring properties <br /> when the well top elevations are surveyed This map can then be used to aid in the <br /> proposal of future work <br /> 5.0 SIGNATURE AND CERTIFICATION <br />' This project will be performed by Geological Technics Inc in accordance with accepted <br /> geologic and hydrologic standards of the State of California accepted and in effect at the time <br /> of this investigation Geological Technics Inc is not responsible for undisclosed conditions <br /> This report was prepared by <br />' G>eofogrca(Tecfmics Inc. <br />' Michael J Niemi <br /> Geologist <br /> ��QQ¢oFes510��F <br /> R i KAXANOw w Of <br /> `(A <br /> Q` NO 5234 <br />' Raynold Iablanow II, Ph D <br /> California Registered Geologist#5234 '!rq� �4 <br /> Certified Hydrogeologist #442 OF CALtFO <br /> • <br /> I <br />
