Significance and Use | ||||||||||||||||
5.1 Withdrawal or injection well test field procedures are used with appropriate analytical procedures in appropriate hydrogeological sites to determine transmissivity and storage coefficient of aquifers and hydraulic conductivity of confining beds. 5.2 Practice D3740 provides evaluation factors for the activities in this test method. Note 2: The quality of the result produced by this standard is
dependent on the competence of the personnel performing it, and the
suitability of the equipment and facilities used. Agencies that
meet the criteria of Practice D3740 are generally considered capable of
competent and objective testing/sampling/inspection/etc. Users of
this standard are cautioned that compliance with Practice
D3740 does not in itself
assure reliable results. Reliable results depend on many factors;
Practice D3740 provides a
means of evaluating some of those factors.
5.3 This test method may be limited due to the correspondence between the field situation determined by this test method and the simplifying assumptions of the analytical Test Methods D4106 or D4106 and D4043. |

1. Scope | ||||||||||||||||
1.1 This test method covers the field procedure for selecting well locations, controlling change (discharge or injection) rates, and measuring water levels used to analyze the hydraulic properties of an aquifer or aquifers and adjacent confining beds. 1.2 This test method is used in conjunction with an analytical procedure such as Test Methods D4105 or D4106 to evaluate the data and determine aquifer properties. 1.3 The appropriate field and analytical procedures are selected as described in Guide D4043. 1.4 Limitations—The limitations of this test method are primarily related to the correspondence between the field situation determined by this test method and the simplifying assumptions of the analytical Test Methods D4105 or D4106 and D4043. 1.5 The values stated in SI units are to be regarded as standard. 1.6 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. 1.6.1 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
