Standard Guide for Sampling and Analysis of Residential and Commercial Water Supply Wells in Areas of Exploration and Production (E&P) Operations

Importancia y uso:

4.1 A supply well provides groundwater for household, domestic, commercial, agricultural, or industrial uses.

4.2 Using a standardized protocol based on an existing industry, domestic or international, standard or approved regulatory methods and procedures to collect water samples from a supply well is essential to obtain representative water quality data. These data can be critical to efforts to protect water uses, human health and safety, and identify changes when they occur. Use of this guide will help the project team to design and execute an effective water supply sampling program.

4.3 It is important to understand the objectives of the sampling program before designing it. Water supplies may be sampled for various reasons including any or all of the following:

(1) identify health and safety risks for potable use prior to exploration in the vicinity,

(2) baseline sampling, at regular intervals for as long as possible, before an operation of concern,

(3) periodic sampling during such an operation,

(4) investigative responses to initial characterization, perceived changes in water quality, or

(5) ongoing monitoring related to known or potential groundwater constituents of concern in the area.

4.3.1 Baseline Analysis on Water Wells—Select a comprehensive list of inorganic and organic analyses for the initial test on potable water wells for use by the well owner in developing a treatment system, if needed.

4.4 Sampling programs should be based on these objectives and be developed in coordination with the prospective laboratory(ies) to ensure its procedures, capabilities, and limitations can be executed safely, meet the needs of the program, protect human health and fulfill regulatory requirements.
