SOP-012 Standard Operating Procedure Aquifer Testing Page 5 of 18 REVISION NO. 0 March 2020 Sharpe Army Depot Wellhead Flow Meter - A meter installed in the water discharge line near the wellhead to measure the discharge (in volume/time) of water by the mechanical pump and controlled by the flow regulator. Procedure This section contains responsibilities, requirements, and procedures for conducting aquifer testing. Slug, specific capacity, and pumping tests are commonly used testing methods to determine the hydrologic characteristics of confined and unconfined aquifers. Consequently, these methods are covered in this section. All aquifer testing to be conducted at a site must incorporate and be tailored to: • Known or expected site-specific conditions • Targeted parameters to be evaluated • Analysis methodology(ies) to be conducted with the test data Consequently, these factors must be considered, and the tests designed well before generation of the project work plans and implementation in the field. The project work plans will specify all necessary details to complete the aquifer testing at a particular site. Aquifer testing information and specifications to be included in the project work plans will include at a minimum the following: • Objectives of the aquifer testing • Aquifer parameters to be evaluated • Type(s) of aquifer tests to be conducted • Exact wells to be used for aquifer testing • Equipment used • Type, duration and frequency of measurements to be made • Additional procedures or requirements beyond those covered in this SOP At a minimum, the following requirements, responsibilities, and procedures described in the following section must be incorporated into the aquifer testing conducted at each site. 3.1 Responsibilities The field task lead and registered/professional geologist are responsible for ensuring that all aquifer testing activities are conducted and documented in accordance with this SOP and any other appropriate procedures, as applicable. Adherence to this SOP will be accomplished through staff training and by maintaining quality assurance/quality control (QA/QC).
