A "high-low" temperature recording <br /> thermometer will accompany comply shipmenta to onoura proper <br /> temperature maintenanca. The samples will be dalivorod to <br /> a t1tato certified laboratory following undnr chain-of- <br /> custody protocol within de hourn of sampling, whanavar <br /> pounible. <br /> Soil in the upparmoct braus tube will bo described according <br /> to ASIAN standard practice for description and lk:jntificatlon <br /> Of soils {ASTM D-2486-04). StratigraphLc, genetic and other <br /> data/interpretations will also be recorded. 5011 proportion <br /> may also be determined <br /> from the middle braon tuba and from <br /> the sampler shoo. Alternatively the second nampla tuba "y <br /> be used with the uppermost tube for Preparation of <br /> duplicates. Those field obaervatlons will be noted on a log <br /> prepared for each boring/well. <br /> During sampling, latex gloves will be worn to pravent croso- <br /> contaaination with other samples.
