<br /> GoIL SAMPLING
<br /> All soil sar,tpling pq,_tiprner,t wil- be thoroughly s'teant-
<br /> cleaned before sarnpiin9 and between anraplir,g to prevent
<br /> cross-ccrrtarninatien. Rea ;,ively ,_rr,disturbed sail vaarnples

<br /> will be taken at inter^vats of noL "'tet- than five feet ials; however, this
<br /> order to evaluate the subsurface mater
<br /> sampling interval may be waived in sa-;Urated sands Or gravels
<br /> in, which saraple recovery is not possible.
<br /> The soil 5;�arnples will be collected using a California
<br /> Modified split--spoor, sarnpler with brass liners. The sarnpler
<br /> t4ill be driven by a 14Cr po,.tr,d haTilmer, repeatedly falling 3Ct
