N6 g ..... ....... MIA SAMPIX CONTAINERS Our firm uses now nomple contniners of the type mpt,ciried by either EPA or the RWQCH for the collection of stimplen at nitan whrre underground storage Lanka are Involved. Water samples ore contained In 40 aril volatile organic analysis vitals (VOAn) when analysis for ganolino and nimilar light volatile) compounds in intended. These contninera are prepared according to FPA SW 846 and will contain ft 51-1till amount of preservative when the analyllin in for T1111 as gasoline or EPA 602. Viola intended for EPA 601 analysis and EPA 624 GCMS procedures are not preserved. Closure is accomplished with an open handed (syringe accessible) plastic screw cup brought down on top of a Teflon faced septum which In used to Beat the sample without headapacc, Water samples intended for nemlvalatile and nonvolatile analyula such as total oil and grease (TOG) and diesel (TPII 1101') are collected and transported in properly prepared new glass liter battles. Dark amber glass in used in the manufacture of these bottlon to reduce any adveren effect on the sample by sunlight. Antimicrobial preservative may be added to the sample liquid It it prolonged holding time is expected prior to analysis. Closure in accomplished with a heavy plastic screw cap. Sol) samples for volatile, Dernivolatile and nonvolatile analyses are all collected in properly prepared new brass liners which are 2 inches in diameter by 4 inches in length. Closure Is accomplished with press fit plastic end caps which are fitted to the open ends of brass tube- 40-fter a sheet of aluminum foil Is wrapped over the exposed sample materiel. A non- contributing/nonsubLractive tape is wrapped completely around the Joint areas where the plastic caps meet the outer wall of the brass tube. No preservative other than cold storage Is used on camples captured in sample containers of this type. SAMPLE HANDLING PROCEDURES Solid sample material is captured by advancing the liner into the soil. This may be done by pushing the liner Into soft soils or by containing the liner in a drive shoe which can be advanced and then retracted by means of a slide hammer. The open ends of the sample liner are covered with alurainum foil and plastic end capit. Excess aluminum roll is removed and the edge of the • plastic end caps is tightly settled against the outer surface of the brass liner with an unbroken wrap made with a Lope which has been tested to confirm that it does not contribute compounds that would be detected In the type of analyses intended for thu sample contained Inside of the brans liner. The brass linar in then labeled with the appropriate Identification numbers which specify the sampling activity designation number, anciple collection area, ---JepLh-etc---that-applr--to-that-particu!nr tam le.-�—The-tam ple finer-is-then --- -- ----- - P pp P � ; p p placed hen- placed In an Ice chest which contains pre-frozen blocks of an Inert Ice substitute such a Blue fee or Super Ice.
