Soil Vapor Sampling SOP Page 1 of 11 <br /> Stantec Rev. 1.0 Apr 2019 <br /> 1.0 PURPOSE & APPLICABILITY <br /> The purpose of this document is to define the standard operating procedure (SOP) for <br /> the installation and sampling of sub-slab and shallow soil vapor points. For purposes of <br /> this SOP, the term shallow soil vapor refers to soil vapor present at approximately five <br /> feet below the ground surface. The ultimate goal of the installation and sampling <br /> program is to obtain samples that meet acceptable standards of accuracy, precision, <br /> comparability, representativeness and completeness. All steps that could affect <br /> tracking, documentation, or integrity of samples have been explained in sufficient detail <br /> to allow different sampling personnel to collect samples that are equally reliable and <br /> consistent. <br /> This procedure provides descriptions of equipment, field procedures, sample containers, <br /> decontamination, documentation, storage, holding times, and field QA/QC procedures <br /> necessary to collect sub-slab vapor and soil gas samples from vapor points. <br /> This procedure may apply to all sub-slab and soil vapor vapor point sampling by Stantec <br /> personnel or their subcontractors. <br /> While the SOP is intended to be strictly followed, it must be recognized that field <br /> conditions may force some modifications to the SOP. Any modification to the procedure <br /> shall be approved by the Project Manager or Task Leader in advance. Where SOP <br /> modification is planned sufficiently in advance, regulatory agency concurrence will be <br /> sought prior to conducting the specific activity. When direct contact with regulatory <br /> agency staff is not possible, or unscheduled delays will result, such as during field <br /> activities, regulatory agency will be notified of deviations from the SOPs, in writing, as <br /> soon as possible after the occurrence. <br /> 2.0 DEFINITIONS <br /> HASP Health and Safety Plan <br /> OSHA Occupational Safety and Health Administration <br /> QA/QC Quality Assurance/Quality Control <br /> QAPP Quality Assurance Project Plan <br /> FSP Field Sampling Plan <br /> SOP Standard Operating Procedure <br /> WP (Project) Work Plan <br /> 3.0 HEALTH AND SAFETY CONSIDERATIONS <br /> Refer to the site-specific HASP for health and safety considerations applicable to sub- <br /> slab vapor and soil gas sampling points. <br /> Consideration of Health & Safety risks prior to performing this work is paramount. This <br /> risk review can be performed by making our generic Job Safety Analysis site specific in <br /> our site-specific HASP. Of course, there are many items that need to be considered. <br /> THIS INFORMATION FOR AUTHORIZED COMPANY USE ONLY <br /> STANTEC CONSULTING <br />
