Soil samples for volatile, scnvvolatile arad nonvolatile analyses are all Collected in prep erly prepared new brass liners which are 2 inches in diamoter'by A inches in length. Closure is accomplished with press fit plastic end caps wtaich are ft-ted to tho open ends of brass tube liners after a sheet of aluminum foil is wrapped over the exposed sample material. No preservative other than cold storage is used er, samples 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 hamtner. Th-,open ends of the sample liner are covered with aluminum foil and plastic end caps. Tire brass liner is labeled wilt the appropriate identification numbers which specify the sampling activity designation number, sample collection area, depth etc, that apply to d0A particular sample. The sample Liner is then placed in an ice chest which contains pre-frozen blocks of an inert ice substi- tute such as Blue Ice or Super Ice. Water samples are collected in any of several appropriate devices such as bailers, Coliwa- sas, Middleburg sampling pumps, etc., which s_-c described in detail only as warramed by their employment at a given site. Sample liquid is decant:d into new sample containers in a manner which reduces the loss of volatile coastitucttr-,and follows the applicable HPA procedures for handling volatile organic and,,m -volarle compounds. Orly two varia- tions from the EPA methods axe gene.-ally employed First, preservative is added to the sample container pror to addition of the sam-- liquid. This method was pioneerrd by Stoner Laboratories in 1982 and subsequently adopted by laboratories and environmental consulting funis as a practical m=ans of reducing Ot time that a liquid is allowed to aerate prior to closure of the sampling container. Second, becaust,, tests have shown that the preservative readily mixes with sample liquid, glass stirring rrK's arc trot used to agitate the sample/preservative mixture. Sample Designations Al sample containers are identified wit![ botF 2 s mpling event number and a discrete sample identification nutnbtr. the sarrplirg zvc^t nunibe is the number that appears on our chain of custody. It is roughly equivaleat to a job number, but applies only to work done on a particular day of the year, ra-lie. than. ;p<nulr:g several days m jobs and projects often do. This is followed by the sample I,D. tai:nber which is use lly a simptc number such as#1, #2, #3.
