Summary of Practice3.1
17、Obtaining soil samples from the surface and subsurfacefor chemical and physical analysis often involves the advance-ment of a core barrel sampler into the ground. A core barrelsampler can be operated by hand or mechanically, and it maybe of a closed or open design (Guide D6282). Once the corebarrel
18、has been filled, the sampler is recovered from the borehole and the soil sample is handled appropriately for thechemical constituents of concern.3.2 This practice describes collection and handling proce-dures used with four types of core barrel samplers. Thestandards related to data quality objectiv
19、es (Practice D5792),equipment specifications (Guides D6232, D6169 and D4700),their limitations and advantages (Guide D6282), and thesite-specific geological and hydrological data should be re-viewed to determine the soil coring equipment that is bestsuited for a specific project.4. Significance and
20、Use4.1 Often during environmental investigations, soils areanalyzed after being collected from the surface, the vadosezone (Terminology D653) and sometimes from below theground water table to identify and quantify the presence of achemical contaminant. A contaminant is a substance that istypically h
21、azardous and either is not normally present or thatoccurs naturally but is of an uncharacteristically high concen-tration (Guide D4687). A three-dimensional spatial array ofsamples can often provide information as to the source androute(s) of migration of the contaminant. The resultant infor-mation
22、is used to direct remedial and corrective actions or canbe used for monitoring purposes. Obtaining a soil sample witha core barrel sampler involves driving this device into theground and then retrieving it for sample processing. Severalmethods for advancing a core barrel are generally acceptable(for
23、 example, Test Method D1586, Practice D1587, PracticeD3550, Guide D4700, Guide D5784, Guide D5875, GuideD5876, Practice D6151, Guide D6282, and Guide D6286).Drilling methods that use drilling fluids (liquids or air) shouldbe avoided because they are more susceptible to cross-contamination (See 5.1.6
24、).5. Equipment Selection Criteria5.1 Important criteria to consider when selecting a corebarrel sampler for soil sampling are:5.1.1 The materials that come into direct contact with thesoil sample (barrel or barrel liner) should be compatible withthe chemical or physical properties of the contaminant
