InterPhase's Standard Operating Procedure For Soil Gas Sampling

Discrete Soil Sampling

Discrete soil samples are collected with the Geoprobe Large Bore (LB) Soil Sampler. The LB Soil Sampler is used to collect depth specific soil samples for chemical analysis and visual inspection

Equipment/Tools

LB Soil Sampler: A 24-inch long x 1-3/8-inch diameter piston-type soil sampler capable of recovering a discrete sample that measures up to 320 ml in volume, in the form of 22-inch x 1-1/16-inch core contained inside a removable liner.

Liner: A 24-inch long x 1-1/8-inch diameter removable/replaceable, thin-walled tube inserted inside the LB Sampler body for the purpose of containing and storing soil samples. Liner materials include brass, stainless steel, Teflon and clear plastic.

Continuous Core Soil Sampling

The Geoprobe Macro Core (MC) Sampler will collect continuous soil samples from ground surface to depth in unconsolidated materials in three to four-foot increments. The MC Soil Sampler is used to collect soil samples at depth and recover them for visual inspection and/or chemical analysis.

Equipment/Tools

MC Soil Sampler: A 48-inch long x 2.0-inch diameter soil sampler capable of recovering a sample that measures up to 1302 ml in volume, in the form of a 45-inch x 1.5-inch core.

Liner: A 46-inch long x 1.75-inch diameter removable/replaceable, thin-walled tube inserted inside the sampler tube for the purpose of containing and storing soil samples. Liner materials include stainless steel, Teflon and clear plastic.
