This <br /> may be done by pushing the liner into soft soils or by eont9ining the lines- <br /> in <br /> inerin a drive ohor whicis can be advanced and then retracted by means of is r lidr. <br /> i hammer. The open ends of the Sample liner are covered with aluminuin foil and <br /> ;.:astic end caps. Excess aluminum foil Is removed and the edge of the <br /> pla-itic and caps is tightly sealed agairsat the outer surface of the brass <br /> line,- with an unbroken wrap made with at tape which hni. been tested to confirm <br /> that it does not contribute* compounds that mould be detected in the type of <br /> an,*:yreo intended for the sample contained innidea of the brass liner. The <br /> brass liner is then labeled with the appropriate identification numbers which <br /> specify the sampling activity dazignation number. sample collection area, <br /> F depth etc. that apply to that particular sample. The sample liner is then <br /> placed in an ice cheat which contains pre-frozen blocks of an inert ice <br /> subatitute sucis a Blues Ice or Super Ice. <br /> a <br /> Stater samples are collected in any of several appropriate devices such as <br /> bailers, Caliwasas, Middleburg sampling pumps etc. Which are described In <br /> detail only an warranted by their employment at a given site.
