PROTOCOL SOIL SAMPLING FOR CHEMICAL ANALYSIS 1.0 INTRODUCTION This protocol describes the procedures to be followed for collecting soil samples for chemical analysis and conducting soil field screening in conjunction with drilling soil borings and excavating soil. The laboratory must be certified by the appropriate regulating agency for the analyses to be performed. If required, permits will be acquired from the appropriate agency, and an underground utility check will be performed before drilling or excavating begins. An underground utility check will, at a minimum, consist of contacting a local utility alert service, if available. The procedures presented herein are intended to be of general use and may be supplemented by a work plan and/or health and safety plan. As the work progresses and if warranted, appropriate revisions may be made by the project manager. Detailed procedures in this protocol may be superseded by applicable regulatory requirements. 2.0 SAMPLE COLLECTION Soil samples may be collected during drilling or excavating activities. The procedures for sample collection are discussed below. 2.1 SAMPLE COLLECTION DURING DRILLING The drilling of soil borings will be conducted in accordance with the protocol DRILLING AND DESTRUCTION OF SOIL BORINGS. The soil sampler will either be washed with laboratory grade detergent-water solution to remove soil present and rinsed with potable water or steam- cleaned prior to and between sampling. Soil samples will be collected in clean brass or stainless steel liners that have been washed with detergent-water solution and rinsed with potable water or steam-cleaned. The liners will generally be placed in a 2-inch- or 2.5-inch- diameter split-spoon sampler and then driven or pushed into the soil at the selected sampling depth. The sample will be parted at the joints between the liners using a clean, sharp stainless steel knife or spatula. Alternatively, a subsample for chemical analyses may also be collected by driving a smaller-diameter liner into the center of the larger core sample, taking care to reduce the potential for sample disturbance and air space within the liner. If the soil sample is collected using a hand auger, a subsample should be collected from the core of the auger, again taking care to reduce the potential for sample disturbance and air space within the liner. If the sample is to be analyzed for non-volatiles only, a loose sample may be placed in a glass H:\AMEC\Field Protocols\Wood Protocols\PROTO-SS 0802.doc SOIL SAMPLING FOR CHEMICAL ANALYSIS Revision Date: February 2015 Page 1 of 5
