1、Designation: D6030 96 (Reapproved 2008)D6030 15Standard Guide forSelection of Methods for Assessing Groundwater or AquiferSensitivity and Vulnerability1This standard is issued under the fixed designation D6030; the number immediately following the designation indicates the year oforiginal adoption o
2、r, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope Scope*1.1 This guide covers information needed to select one or more methods for
3、assessing the sensitivity of groundwater or aquifersand the vulnerability of groundwater or aquifers to water-quality degradation by specific contaminants.1.2 This guide may not be all-inclusive; it offers a series of options and does not specify a course of action. It should not beused as the sole
4、criterion or basis of comparison, and does not replace professional judgment.1.3 This guide is to be used for evaluating sensitivity and vulnerability methods for purposes of land-use management,water-use management, groundwater protection, government regulation, and education. This guide incorporat
5、es descriptions ofgeneral classes of methods and selected examples within these classes but does not advocate anya particular method.1.4 LimitationsThe utility and reliability of the methods described in this guide depend on the availability, nature, and qualityof the data used for the assessment; t
6、he skill, knowledge, and judgment of the individuals selecting the method; the size of the siteor region under investigation; and the intended scale of resulting map products. Because these methods are being continuallydeveloped and modified, the results should be used with caution. These techniques
7、, whether or not they provide a specific numericvalue, provide a relative ranking and assessment of sensitivity or vulnerability. However, a relatively low sensitivity orvulnerability for an area does not preclude the possibility of contamination, nor does a high sensitivity or vulnerability necessa
8、rilymean that groundwater or an aquifer is contaminated.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 All observed and calculated values shall conform to the guidelines for significant digits and rounding established
9、 in PracticeD6026.1.6.1 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industrystandard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do notconsider material v
10、ariation, purpose for obtaining the data, special purpose studies, or any considerations for the users 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 signi
11、ficant 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 responsibilityof the user of this standard to establish appropriate safety and health practices and determine the appli
12、cability of regulatorylimitations prior to use.1.8 This guide offers an organized collection of information or a series of options and does not recommend a specific courseof action. This document cannot replace education or experience and should be used in conjunction with professional judgment.Not
13、all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replacethe standard of care by which the adequacy of a given professional service must be judged, nor should this document be appliedwithout consideration of a projects many unique as
14、pects. The word “Standard” in the title of this document means only that thedocument has been approved through the ASTM consensus process.2.
