Soil gas sampling would be a great option. Title: Standard Operating Procedure for Solid Stem Auger Drilling Investigations . This sampler is ideal for sites where soil, soil gas and ground water samples all need to be collected in the same borehole. Cross-contamination problems can be eliminated or minimized through the use of dedicated sampling equipment and bottles.

Subsequent soil samples are obtained with a split-spoon sampler at five-foot intervals in each soil test boring, in accordance with ASTM protocols, to the total depth of the borehole.

Soil samples from all borings are visually classified in accordance with the Unified Soil Classification System and are inspected for visual and odorous evidence of contamination. This Standard Operating Procedure (SOP) provides operating guidelines and instruction solid stem auger for drilling investigations. Introduction and Scope .

Develop.

Potential Problems Potential problems with soil sampling include cross-contamination of samples and im­ proper sample collection. There are a series of steps to taking soil gas samples, including the following: 1. DTD’s sampling process ensures accurate and reliable results. The Project Work Plan will state the reason for performing the soil gas sampling and describe the investigation in detail. Tripod […] Specialized samplers travel downhole in a closed position to prevent soil from collecting in the tooling before reaching the location of interest. Our groundwater sampling training courses (CPD accredited by the Geological Society) are designed to raise understanding and provide hands-on experience of the technologies and processes available for taking the most appropriate sample possible from a borehole or well.

Develop a Project Work Plan, including a Health and Safety Plan.

Standard Penetration Test (SPT) Procedure Aim To perform standard penetration to obtain the penetration resistance (N-value) along the depth at a given site.

These four groundwater sampling methods are some of the most common—but there are other options. Solid Stem Auger/Soil . TITLE: SOIL SAMPLING CATEGORY: ENV 3.13 REVISED: August 1997 5.

Prior to tripping a sampler downhole a drill bit cuts a borehole, stopping just short of the desired sampling location.
