' Ma 23, ?3_9_-_Pace 4 ef_5Re: 1 W. Turner Road, Lodi, CA <br /> a distance of approximately 50 feet past the last evidence of contamination. The <br /> well vqill be 3 inches in diameter to a depth of 50 feet, Since groundwater eras <br /> encountered around 45 feet this 4,'111 be sufficient to obtain groundwater samples <br /> for analysis. The monitoring and sample wells installed by G.T.I. all showed no <br /> ntamination. Water samples can also be taken from the 3 idle <br /> sign of groundwater co <br /> industrial wells before they are permanently abandoned. The owners wish to cooperate <br /> in every manner necessary to bring this clean up to an expedient end. <br /> Remediation Steps: Plans for bioremediation by use of controlled bacteria are now in <br /> 4. the process of being finalized in dealing with the contamination on site. Since the <br /> only contaminates are diesel fuel and heavy bunker oil, this methodology will work <br /> for fatal soil cleanup. The soil will be placed approximately 3 to 4 feet thick an <br /> Y the existing concrete slab and fertilized with ammonium nitrate.. The soil will be <br /> kept moist by using soaker hoses placed at regular intervals to insure maximum <br /> bacteria growth. Bacteria will then be introduced, through this watering system. <br /> The soil will be mixed by using a disc plow and turned over at regular intervals. <br /> Samples will be taY.en for analysis by Canonic Environmental on a monthly basis and <br /> copies will be rade available to S?LNQ. After the contaminayed sell has been rendered <br /> "non-detectable" for all constituents of petroleum hydrocarbons, the soil will be used <br /> on site. <br /> 5- Laboratory that will collect samp es: Canflnie Environmental, Stockton, CA 983-1340 <br /> A signed "Release of lnf ormation Authorization" is attached. <br /> of an - after excavation <br /> —�lGe view o� the excavat_i� <br /> X <br /> TO j' " <br />
