M CDIM Standard Operating Procedure 2.2 Surface and Shallow Soil Sampling N O I N i R N Y Rev.0 1/27/2022 2.5 Undisturbed Soil Sample A soil sample whose in situ physical structure and fabric has not been disturbed as the result of sample collection. 2.6 Grab Sample Disturbed soil sample that is collected by using such devices as a shovel, stainless steel spoon, etc. 3. PROCEDURE This section describes the procedures to collect surface and shallow subsurface soil/sediment samples that will insure the quality and integrity of the samples. The procedures in this SOP should be used in conjunction with project work plans. Project work plans will generally provide the following: • Sample collection objectives; • Soil sample locations and depths; • Number of soil samples and their volumes; • Analysis to be conducted for each sample; • Specific QC procedures and sampling required; and • Any additional surface or shallow subsurface soil sampling requirements or procedures beyond those covered in this SOP, as necessary. The following subsections outline procedures for surface and shallow subsurface soil/sediment sampling. 3.1 Responsibilities The project manager is responsible for ensuring that all sample collection activities are conducted in accordance with this SOP and any other relevant procedures included in project work plans and/or quality assurance project plans (QAPP). The project manager is therefore also responsible for ensuring that staff working on the project is properly trained in this SOP and other relevant procedures to ensure quality assurance/quality control (QA/QC). The project manager may also choose to take on the role and responsibilities of the project QA manager (see below), when appropriate. A project QA manager designated by the project manager is responsible for periodic review of field generated documentation associated with this SOP. The QA manager is also responsible for implementing corrective actions (i.e., retraining personnel, additional review of work plans and SOPs, variances to QC sampling requirements, issuing field variances, etc.) to address deficiencies before problems may occur. The project manager will designate a field coordinator who is responsible for all field activities, including preparations and demobilization. The field coordinator oversees all field personnel to ensure that sampling is being conducted in accordance with the relevant SOPs and 2
