SOP-008 Standard Operating Procedure <br />Well Development Page 1 of 5 REVISION NO. 0 March 2020 <br /> <br />1.0 Introduction <br />1.1 Purpose <br />The purpose of this standard operating procedure (SOP) is to provide guidance for developing temporary and permanent monitoring and extraction wells after their installation and before their designated use. This method may also be used as part of rehabilitation or re-development of a well during its lifecycle. <br />1.2 Responsibilities <br />Project Manager (PM) – The PM is responsible for providing adequate resources to the field staff and ensuring that field staff has adequate experience and training to successfully comply with the SOP. The PM is responsible for approving and documenting techniques that are not specifically described in this SOP, but are considered the best sampling methods for the current project. <br />Site Safety and Health Officer (SSHO) – The SSHO oversees site-specific health and safety activities and ensures compliance with the project requirements. The SSHO conducts personal protective equipment (PPE) evaluations, selects the appropriate PPE, lists the requirements in the site-specific safety and health plan (SSHP), and coordinates with the field team to implement the SSHP. <br />Sampler/Technician – The sampler or technician is responsible for the monitoring or extraction well development as specified in this SOP. <br />2.0 Relevant Documents <br />This SOP is intended to be used in conjunction with the following SOPs: <br />• SOP-002: Field Activity Records <br />• SOP-006: Mud Rotary Drilling <br /> <br />3.0 Definitions <br />Bailer – A long, narrow, tubular device with an open top and a check valve at the bottom that is used to remove water and sediment from a borehole or well. <br />Bailing – A well development technique using a bailer that is raised and lowered in the well to create a strong inward and outward movement of water from the formation, to break sand bridges and to remove water and fine-grained materials from the well. <br />Investigation-derived waste (IDW) – Waste that is generated in the process of investigating or examining a contaminated site. <br />Mechanical surging – A process that uses a plunging motion (usually via a surge block) to force water to flow through a well screen. A pump or bailer is then used to remove dislodged sediment.
