A hollow stem soy' auger should be <br /> $) used to drill to the desired sampling depth. A standazd <br /> r 2 inch diameter split spoon sampler 18 inches in length <br /> shall be used to collect the Samples. The samples are <br /> 5 contained in 2 inch diameter by 6 inch long thin walled <br /> v brass tube liners fitted into, tho split spoon sampler <br /> (three per sampler) . <br /> The split spoon sampler shOuid be driven the full depth. of the spoon into the soil using ,a X40 pound hammer. <br /> s The spoon shal?' then be extracted from the borehole and <br /> the brass tube liners containing the soil sample removed <br /> from the sampler. 'The end's of the liner tubes should be <br /> immediately cc,rrred with alurmintm foil, seated with a <br /> <: teflon or p1a',I i cap, ancY then taped with duct tape. <br /> s After being (groperly identified with sample data entered <br /> on a standnLed chain of custody form the samples shall be i <br /> placed fdry ice.
