Soy'_ samples dill be coliected at five Fcot internals, at <br /> charges in li.thology and intervals of obvious contamination <br /> in orde- t^ develop a complete profile of sol1 contam-natzon. <br /> The soil samples stall not be composited. Soil borings 4111 <br /> extend through the entire interval of contaminated soil and <br /> will terminate if saturated soil interval is encountered. <br /> a r� <br /> Sample Collection During ianx Removal <br /> Soil samples will be collected as soon as possible after <br /> removal of the tank where feasible, all preparations for <br /> x• soil sampling will be made prior to tank removal. Soil <br /> samples collected from a backhoe bucket or dirF-ctly from the <br /> excavation floor will be collected in a thin-w=fled stainless <br /> A steel or brass cylinder at least three Lnches long by one <br /> inch in diameter From 3 to 24 inches of soil will be <br /> ramoved from the -mmediate surface area where the sample Is <br /> to ce taken and the cylinder then pounded into the soil with <br /> a wooden mallet, sulk density driver, or other decontaminated <br /> driving device. Nto head space will be present in the <br /> cylinder once the sample is collected. Care 41.11 be taken to <br /> avoid contamination of cosh the inside and outside of the <br /> cylinder as well as its contents. Durrrg samplirg, late.c <br /> gloves will be worn to prevent cross contamination with other <br /> samples One pair of disposable gloves will be dedicated <br /> to aac.' sample collected. <br /> k <br /> Once the sample Is :ollected, each end of the cylinder wiIi <br /> De covered art' aluminum f011 or teflon gape and then capped <br /> with a polyethylene '.id, taped, and laceled. The sample will <br /> then oe individually sealed in a ziplock bag and immediately <br /> placed in an ice chest containing dry ice or frozen 'blue <br /> ice" for delivery to a state certified laboratory. Sample <br /> " identification, storage and transportation w,ll be condlcted <br /> as outlined in the previous c.-ction. <br /> 3 Sampling from Soil ?ales or Shallow Soil Pats <br /> Soil samples will be collected and transported from excavated <br /> mater-al in the manner described in the previous section, <br /> however, a backhoe will not be utilized . If composite <br /> samples are collected, four brass cylinders 4ili be collected <br /> for every 50 cubic yards cf material to be sampled unless <br /> otherwise specified by the lead regulatory agency. The <br /> samples will be composited by the state certified analytical <br /> laboratory personnel prior to testing. <br />
