ASTM D5521-05<\/h3>\n

Historical Standard: Standard Guide for Development of Groundwater Monitoring Wells in Granular Aquifers<\/h4>\n
\n

ASTM D5521<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This guide covers the development of screened wells installed for the purpose of obtaining representative groundwater information and water quality samples from granular aquifers, though the methods described herein could also be applied to wells used for other purposes. Other well-development methods that are used exclusively in open-borehole bedrock wells are not described in this guide.<\/p>\n

1.2 The applications and limitations of the methods described in this guide are based on the assumption that the primary objective of the monitoring wells to which the methods are applied is to obtain representative water quality samples from aquifers. Screened monitoring wells developed using the methods described in this guide should yield relatively sediment-free samples from granular aquifer materials, ranging from gravels to silty sands. While many monitoring wells are considered \u201c<\/span>small-diameter\u201d<\/span> wells (that is, less than four inches in inside diameter), some of the techniques described in this guide will be more easily applied to large-diameter wells (that is, four-inches or greater in inside diameter).<\/p>\n

1.3 The values stated in inch-pound units are to be regarded as standard. All other units in parentheses are provided for information only.<\/p>\n

1.4 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.<\/span><\/p>\n

1.5 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word \u201c<\/span>Standard\u201d<\/span> in the title of this document means only that the document has been approved through the ASTM consensus process.<\/span><\/p>\n
