Solt samples for volotila, somivolatile and nonvolatile analyses are all collected In property prepared now Grass liners which are 2 Inchon In diameter by 4 Incites in length. Closure la accomplished with prone fit pinstle end cape which are fitted to the opera ends of bran tube after as sheet of aluminum foil Is wrapped over the exposed sample mn(arial.

Nv) preservative other than cold storage in ur*ad on samples captured In sample containera of this type. SAMPLE ItANDL1NC PROCEDURES Solid sample materiel Is captured by advancing the liner Into the toil. This muy be done by pushing the liner Into soft soils or by containing the liner In a drive shoo which can be advanced and then retracted by means of a aalids hammer. The open ends of the sample liner are covered With aluminum foil and plastic end caps. Elccess aluminum~ toil is removed and the edge of the ;elastic end caps Is tightly sealed against the outer surface of the brass liner with an unbroken wrap made with a tape which has been tested to confirm that It does not contribute compounds that would be detected In the type of analyses Intended for the sample contained inside of the brans liner. The brass liner is then labeled with the appropriate Identification numbers which specify the crimpling activity designation nuenber, sample collection area, depth etc. that apply to that particular sample. The sample liner is then placed In an Ice chest which contains pro-frozen blocks. of an Inert Ice substitute such a Blue Ices or Super Ice. Witter samples, are collected In any of severs) appropriate crevices such as baallera, Coliwasas, Middleburg sampling pumps etc. which area described In detail only as warranted by.their employment at a given Rita. Sample liquid Is decanted Into new sample containers In a manner which reduces the lowx .sf volatile constituents and follows the applicable EPA procedures for handling volatile organic rind seta!-vointile compounds.
