The blows required to drive the sampler <br /> each six inch interval will be recorded on ttie boring log- <br /> The sampler will be removed from the boring and opened to <br /> reveal the brass tubes. The bottom tube <br /> will e sealed <br /> with with <br /> aluminum foil and plastic end caps, -taped ro ect ID, sample <br /> the following information: date, time, p <br /> ID, name of sampler and type of analysis.

The samples will be delivered to <br /> a state certified laboratory following under chain-of- <br /> custody protocol within 48 hours of sampling, whenever <br /> possible. <br /> Soil in the uppermost brass tube will be described according <br /> to ASTM standard practice for description and identification <br /> of soils (ASTM D-2488•-84). Strati.graphic, genetic and other <br /> data/interpretations will also be recorded. Soil properties <br /> may also be determined from the middle brass tube and from <br /> the sampler shoe.
