Soil samples may be collected using a 2 inch (i.d.) modified California split <br /> k spoon sampler,or continuous coring device,lined with brass sample tubes. <br /> 2.2 Boring Logs <br /> _i <br /> A detailed log will be made of each boring. The information to be noted includes: sample depths, <br /> blow counts if continuous coring devise is not used, horizons of detectable contamination (detected <br /> by field methods), soil classification utilizing the Unified Soil Classification System and sediment <br /> description (color,texture, composition, hardness, moisture content, and post-depositional changes <br /> that have occurred in the sediments). <br /> 2.3 Cross Contamination Prevention <br /> All sample equipment (split spoon sampler or core tube, brass tubes etc.) and auger (drilling rod, <br /> =: drilling bits, & auger, etc.) will be thoroughly cleaned before being used and between use Wash <br /> water may be containerized in DOT approved 55 gallon drums,labeled,and stored on site until their <br /> disposition can be arranged. Plastic gloves will be worn during sample collection and changed <br /> between all samples. <br /> 2.4 Chain of Custody <br /> Chain of Custody(CofC)forms are legal documents used to track the handling of samples All dates, <br /> times, persons and their companies will be listed from the time the sample is collected to its ultimate <br /> disposal.
