Once tho wall In purgad and indicator <br /> paramotoru have utabillzod, a nample will be collected otter <br /> the water level approachou 00 percent of Ito Initial <br /> elevation. Where ;rater level recovery Is slow, the aamplra <br /> will bra eollectecj after stabilization is achlovad and andugh <br /> waster in present to fill sampla containors. <br /> Cross Contamination i'rom transferring pumps (or bailaaru) <br /> from wall to wall will be avoided by utilizing dedicated <br /> aquipment. Wha_.ka this is not feasible, thorough cleaning of <br /> oquipase+nt will be performed between sampling rounder. <br /> Sampl,iaeg will proceed fro* the least contaminated to the <br /> moat cont"Inated wall, if Information is available before <br /> aamplo collection, or if it is indicated by f101d evidence. <br /> Whard several tygau of analysis will be performed for a <br /> given well, individual samples will be collected in the <br /> following order: <br /> 1. Volatile organicas <br /> 2. Purr,)oabio organic carbon <br /> 3. Rurgeaablee organic halogens <br /> 4. Total organic carbon <br /> 5. Total organic halogens <br /> 6. Extractable organics <br /> 7. Total metals <br /> S. Diessolyed notals <br /> 9. Phenols <br /> 30. Cyanide <br /> s The specific analytical methods be utilized for the co=on <br /> volatile/s0mivol8til0 to analyses arcs shoran on Table 2. <br /> Groundwater a3mplcan will be Collected with is teflon baiter <br /> with botte;m e~ l�tying devicta. Duplicate samples will be <br /> transferred to vials or Containers that most Regional Board <br /> specifications (Tables 1). Groundwater from thea bailt,r will <br /> be transferred to the sample container by all(r4ing the fluid <br /> to floes slowly along the sides of the vessel. All <br /> Containers will ',a filled above the top of thea opening to <br /> forts a Positive eec?niaCuta. No head space should be present <br /> in the sample, Container once it is scaled. After the vial in <br /> capped it will be Inverted to check for air bubbles. If <br /> bubbles are present tha sarsple will be discarded and <br /> replaced. If it is net possible to collect a sample without <br /> head apace, the problem will bas noted on the field <br /> technician's sampling log. <br /> I�ttiately-follting-�r�p1e--Ctallaction, z3rsplas will be - _-- -- -- <br /> labeled and stcred in an ic,,4 chest containing frozen <br /> chaaieal ice scaled in plastic begs. Sampla labels will <br /> contain the following information: date, time, projczct ID, <br /> sasmple ID, name of sampler and type of analysis. All <br /> Saabs will be transported undex C gain-oi-custoafy protocol <br /> `. to a state cartifiead laboratory within 24 hours.
