While drilling, an exptnimiced <br /> environmental geologist classifies the soil,logs the stratigraphy of the borings, and collects soil <br /> samples. <br /> It-2.2 QpulitativeField Screening <br /> An organic vapor detector, shell as a Pbotovac TIP, esiug a photo-ionization detector(PTD) or a <br /> Foxboro flame-ionization detector (Ff D), is used to provide a qualitative screening, of each soil <br /> samplo collcctod frori tho borings, when appropriato. The organic vapor d:tee:or measures <br /> ionizable compounds in the air is parts per milliett by volume (ppmv). Field calibration is <br /> performed using a caliluared spat gas such as 100-ppm>cobutylene. Ambient air is used to act <br /> the instrument to zero. The soil contained in the cone of the sampler or in a brass tube is <br /> exposed and screenad with tine urgmyc: vapor detector. The vapor reading is meted as the field <br /> C <br /> screening result. <br /> 17or tide [d3:eertin of Il:@ cnilil" l'.'dx tlx Ominie vapcT d2`JC[Or R'sc- is aied to 212:Sure ff: <br /> volatile concentrations in the breaching zone prier to and ;vhil- dritlio.R the bori l;s.
