Data are gathered at ground-water sites for many purposes. Each purpose requires a different combination of data elements. However, it is mandatory that every ground-water 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 D 5254.

As a part of a ground-water 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 ground-water 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 ground-water sites. The data elements are described in four ASTM standards outlining information that may be collected at ground-water 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. Note 1A ground-water site is any source, location, or sampling station capable of producing water or hydrologic data from a natural stratum from below the surface of the earth. A source or facility can include a well, spring or seep, and drain or tunnel (nearly horizontal in orientation). Other sources, such as excavations, driven devices, bore holes, ponds, lakes, and sinkholes, that can be shown to be hydraulically connected to the ground water, are appropriate for the use intended.

Note 2

The four ASTM standards that describe the data elements for ground water are Practice D 5254 and Guides D 5408, D 5409, and D 5410.

1.2 Systematic and consistent data collection are necessary for the investigation of the availability and the protection or restoration of ground-water 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 ground-water 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.

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.

1.3 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.
