5.1 Data are gathered at groundwater sites for many purposes. Each purpose requires a different combination of data elements. However, it is mandatory that every groundwater site include a minimum set of data elements to uniquely identify that site by precisely locating with coordinates and political regimes, absolutely identifying the owner and data source, and clearly defining the basic site characteristics. This information is described in Practice D5254. 5.2 As a part of a groundwater project, each site requires additional data elements, beyond the minimum set, to assist in the interpretation of the local and areal hydrology. As an example, for a hydrologic reconnaissance study of a groundwater basin, each well or spring site requires basic information concerning construction, water level, yield, geology, and water chemistry. Additional information is needed if the project is a waste facility investigation, usually to satisfy local, state, and federal environmental regulations. |

1.1 This guide covers the selection of data elements for the documentation of groundwater sites. The data elements are described in four ASTM standards outlining information that may be collected at groundwater sites. Examples of specific investigations are given with the logic of why to select individual and combinations of data elements to meet the requirements of the studies. 1.2 Systematic and consistent data
collection are necessary for the investigation of the availability
and the protection or restoration of groundwater resources. The
level of detail, precision and bias, and the type of data that need
to be collected depend on the objective of the study, the expected
complexity of the system, and the resources available for the
investigation. This guide presents ideas on what information should
be collected for specific studies, why certain data elements are
mandatory, and the importance to current and future investigations
of maintaining quality control on the collection and retention of
these data. This guide focuses on those data elements that are
gathered at the field-site location and are used to assist in
interpreting the hydrology of the groundwater source and to meet
regulatory requirements. Other analytical and quality
assurance/quality control (QA/QC) considerations are addressed in
other standards and beyond the scope of this guide.
1.3 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. 1.4 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 “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. |
