• <br /> GETTLER-RYAN INC. <br /> FIELD METHODS AND PROCEDURES <br /> Site Safely Plan <br /> Field work performed by Gettler-Ryan Inc (G-R) is conducted in accordance with G-R's <br /> Health and Safety Plan and the Site Safety Plan G-R personnel and subcontractors who <br /> perform work at the site are briefed on the contents of these plans prior to inntnating site <br /> work The G-R geologist or engineer at the site when the work is performed acts as the Site <br /> Safety Officer G-R utilizes a photoionization detector (PID) to monitor ambient conditions <br /> as part of the Health and Safety Plan <br /> Collection of Soil Samples <br /> Soil samples are collected from the wall or base of the excavation with a hand-driven <br /> sampling device fitted with a 2-inch-diameter, clean brass tube or stainless steel liner After <br /> removal from the sampling device, soil samples are covered on both ends with teflon <br /> sheeting, capped, labeled, and place in a cooler with blue ice for preservation A chain-of- <br /> custody <br /> hain-ofcustody form is initiated in the field and accompanies the selected soil samples to the <br /> analytical laboratory <br /> Field Screening of Soil Samples <br /> A PID is used to perform head-space analysis in the field for the presence of organic vapors <br /> from the soil sample This test procedure involves placing a small amount of the soil to be <br /> screened in a sealable plastic bag The bag is warmed in the sun to allow organic compounds <br /> in the soil sample to volatilize. The PID probe is inserted through the wall of the bag and <br /> into the headspace inside, and the meter reading is recorded in the field notes Head-space <br /> screening is performed and results recorded as reconnaissance data only G-R does not <br /> consider field screening techniques to be verification of the presence or absence of <br /> hydrocarbons <br /> Grab Groundwater Sampling <br /> Grab samples of groundwater are collected from the bormg using a bailer The groundwater <br /> sample is decanted into laboratory-supplied containers appropriate for the anticipated <br /> • analyses Sample bottles are then labelled and placed in chilled storage for transport to the <br /> A-1 <br />
