AMS AMS1 Soil Sampling Auger Kit

Overview

The AMS AMS1 Soil Sampling Auger Kit is a field-deployable, manually operated mechanical soil coring system engineered for consistent, depth-controlled subsurface sampling in heterogeneous geological and environmental settings. Designed around the principle of rotary augering with positive core retention, the kit enables reproducible collection of undisturbed cylindrical soil cores up to 274 cm (9 ft) deep — a critical capability for vadose zone characterization, contaminant plume delineation, geotechnical profiling, and regulatory compliance sampling under ASTM D1586, ISO 22475-1, and EPA Method SW-846 5035A. Its modular architecture integrates standardized 5/8″ UNC threaded connections and SDS-Max compatibility, allowing seamless coupling with both hand-held percussion drivers and rotary hammer drills commonly deployed on-site by environmental consultants, remediation contractors, and government agencies.

Key Features

• Modular depth extension system: Includes two 91.44 cm (36″) threaded extension rods and three 121.92 cm (48″) 5/8″-threaded rods, enabling incremental depth progression while maintaining structural rigidity and torque transfer efficiency.
• Dual-diameter auger configuration: A 5.08 cm (2″) OD flighted auger with hardened tip ensures efficient penetration through compacted soils, gravel lenses, and weathered bedrock; paired with a 3.81 cm (1.5″) OD stainless steel core sampler for high-fidelity sample recovery.
• Core integrity preservation: The 15.24 cm (6″) length core sampler features precision-machined internal geometry and smooth bore finish to minimize shearing and smearing during extraction — essential for moisture content, bulk density, and contaminant distribution analysis.
• Toolset integration: Includes a sliding hammer for percussive advancement in dense strata, an adjustable universal wrench for rapid rod assembly/disassembly, a nylon bristle brush for post-use cleaning of flights and core barrels, and a carbide-tipped 5.08 cm drill bit for pre-boring in highly abrasive or rocky matrices.
• Transport & durability: All components are housed in a reinforced polymer carrying case with custom-cut foam inserts, conforming to IP65 dust/water resistance standards for field logistics and long-term storage.

Sample Compatibility & Compliance

The AMS1 kit supports sampling across a broad range of soil textures — from loose sands and silts to clay-rich, moderately cohesive deposits — without requiring hydraulic or pneumatic support systems. Core recovery rates exceed 90% in non-caving formations per ASTM D1587 practice. All metallic components comply with RoHS Directive 2011/65/EU and are manufactured from ASTM A276 Type 304 stainless steel (core sampler) and AISI 4140 alloy steel (auger flights and extensions). The system is routinely validated for use in projects governed by U.S. EPA Region-specific Quality Assurance Project Plans (QAPPs), California DTSC Field Sampling Protocols, and EU CLP Regulation Annex VI reporting frameworks.

Software & Data Management

While the AMS1 is a hardware-only mechanical sampling platform, it is fully compatible with industry-standard digital field data capture workflows. Sample metadata—including GPS coordinates (via Bluetooth-enabled GNSS receivers), depth intervals, stratigraphic notes, and photo documentation—can be logged directly into ESRI ArcGIS Field Maps, QField, or EQuIS Mobile. All physical sample identifiers (e.g., core tube labels, barcode tags) align with LIMS-integrated tracking protocols compliant with ISO/IEC 17025:2017 clause 7.5.2 (sample handling) and FDA 21 CFR Part 11 audit trail requirements when paired with validated electronic lab notebooks.

Applications

• Phase I/II Environmental Site Assessments (ESAs) per ASTM E1527 and E1903
• Soil gas probe installation and vapor intrusion investigations
• Agricultural soil health monitoring (organic carbon, nutrient stratification)
• Landfill cover system performance verification
• Archaeological test pitting and cultural resource management (CRM) surveys
• Regulatory-driven soil screening for metals, PAHs, PCBs, and petroleum hydrocarbons

FAQ

What is the maximum recommended sampling depth using the standard AMS1 configuration?

Up to 274 cm (9 ft) — achieved using the full complement of extension rods and proper torque management in cohesive soils.
Can the AMS1 be used in rocky or gravelly soils?

Yes, when paired with the included carbide-tipped drill bit for pilot hole creation prior to auger advancement.
Is the core sampler compatible with standard laboratory subsampling tools?

Yes — the 3.81 cm diameter and 15.24 cm length conform to ASTM D4220 and ISO 14688-1 dimensional conventions for split-spoon and thin-walled tube sample handling.
Does the kit meet OSHA or ANSI safety standards for field equipment?

All hand tools (wrench, sliding hammer, brush) comply with ANSI B107.1-2020; auger assembly procedures follow OSHA 1926.651(c)(1) trenching and excavation best practices.
Are replacement parts available separately?

Yes — individual components including flighted augers, core samplers, extension rods, and SDS-Max adapters are stocked under AMS part numbers and distributed globally through authorized channels.
