Immediately transfer plug to the sample vial with <br /> methanol by using plunger. Clean around lip of vial to <br /> remove soil with clean laboratory paper toweling and <br /> seal septum onto the vial with lid, TeflonH-side <br /> (shiny) toward the sample. Shake sample enough to <br /> brea]c it up so that whole sample ;s immersed in <br /> 7aethanol. The rapid progression of steps indicated <br /> here is necessary to prevent loss of volatiles f,om the <br /> soil. Do not leave vials unopened for any extended <br /> Period - the methanol evaporates quickly. Grit left on <br /> threads of vial can cause vial to break. <br /> F. If required (see 5 below) , Take a duplicate sample <br /> from the other half directly across from the first <br /> sample, or wherever undisturbed, yet representative <br /> soil occurs. <br /> G. Label vial with legible information as follows: <br /> 1. Job name or number. <br /> 2. Date. <br /> 3. Time. <br /> 4. Depth and well number. <br /> 5. Samplers initials. <br /> H. Tape vial across septum with Scotch tape and ground cap <br /> and sign on the tape with indelible ink to prevent <br /> tampering. <br /> I. Wrap up a representative section of the core equivalent <br /> in volume to cube three centimeters on a side in the <br /> aluminum foil square, discarding the rest approp- <br /> riately. seal in Saran wrap. This section is for dry- <br /> weight determination. Close it in.plastic bag with a <br /> tag or write on the bag with an inaglible marker. <br /> These samples go into a separate cooler or box and not <br /> with the vials. The cooler for dry-weight samples need <br /> not be iced, but overnight delivey is requested. <br /> - J. Discard plastic-coring syringe, clean the spatula, and <br /> get clean equipment ready for next sample. <br /> GNcwND%%ATEN <br /> TECI{�nIaK:1'.A1C. <br /> 11 No NO MIN <br /> i <br /> kr <br /> �i <br />
