Abstract
The Delaware Geological Survey (DGS) has measured, managed, and distributed groundwaterlevel
data for several decades using widely accepted procedures and practices, many of which
were derived from interactions with staff of the USGS, consulting firms, and other state
agencies. Many of the individual methods and procedures have been described in DGS reports,
however, written documentation for these tasks have not been assembled in a single published
document. The need for such a document has become more apparent with the development of
standards for participation in the National Ground-Water Monitoring Network (SOGW, 2009).
This document describes methods used by the DGS for routine manual and automated
measurement of groundwater levels in dedicated monitoring wells. Alternative methods used for
manual measurement of water levels in other types of wells are noted in this document to provide
reference for historical measurements but not described in detail.
These methods are excerpted and modified from procedures described by federal agencies and
national standards organizations (e.g., ASTM, D4750-2007; Drost, 2005; USEPA, 2007). In this
document, the term water levels will be used interchangeably with groundwater levels. Please
refer to these and other appropriate documents for additional guidance or contact DGS staff with
specific questions.
Practices pertaining to data processing and management, metadata, and quality assurance
procedures for electronic data are rapidly evolving. Additional sections on these topics will be
added to this document as time and resources permit.
