2. Upon arriving at the sample station, the zzoprtnt rubber tns of the sample lines are <br />checked for dirt an4 dust accumulation. if necessazy. the sample, lines am flushed with <br />f distilled water. <br />z <br />I The pmssutrelvacuurrz line is connected to the vacuum gage of the vacuum bud pump. <br />The clarnP on the vacuum line is opened and the residual vactmm, remi ,ing <br />on the, <br />lysimctex unit is measured adrecorded can the lysimew sampling lug. <br />4. Theuis connected to the Pressmt pump and the discharge (s=pl,) <br />lino opened. The discharge line is insated into a zlcaa, unpresetyed I liter plastic bottle <br />prepared and supplied by the analytical laboratory. <br />The pressum pump is activated, forcing - o -the lysim-tter. if additional pressure, is <br />needed to retrieve the fluid morc quickly, the pressure is increased InWl adequate flow is <br />achieved, <br />6ThC sample is split toothei appropriatclypreserved bottles as nd I cessary 'for the analytical <br />requirements, The sampIcs art placcd in an ice -filled chest to M�jjumin a teMp==U.0 <br />approximate!Y4 degrees Celsius dudng delivery to the laboratory under chain.,of-custody <br />procedures. <br />7- After the sarnplc is collected, <br />Manufactured rr=mmended value using a'hand vaca= pump.
