The Environmental Data Standards Council (EDSC) is a partnership among
US EPA, States and Tribal partners to promote the efficient sharing of
environmental information through the development and adoption of data
standards. More information about the EDSC is available at
[www.envdatastandards.net](http://www.envdatastandards.net/).

**Foreword**

The Environmental Data Standards Council (EDSC) is a partnership among
US EPA, States and Tribal partners to develop and agree upon data
standards for environmental information collection and exchange. The
Council seeks to promote efficient sharing of environmental information
between State, US EPA and Tribal partners through the development of
data standards. More information about the EDSC is available on the EDSC
website at http://www.envdatastandards.net/.

**1.0 INTRODUCTION**

Environmental information is a key tool in the effective management of
our environmental resources and human health conditions. As a result,
much effort goes into data acquisition, management, maintenance,
exchange, and oversight. Greater access is the goal of many data
consumers, and data managers. Providers invest significant resources
meeting their requirements. In response, many data providers are
improving access as they post usable copies of their environmental
information on the web. These efforts are a vast improvement over
previous conditions; however, there is a growing desire and need to both
provide and receive data in a clearly defined and a uniform way. Data
from multiple sources can then be aggregated and used without the
inherent variations that exist between data sets across agencies.

**1.1 Scope**

This EDSC standard describes data elements and data groupings that are
used to exchange information about wells and is a supplement to the
ESAR: Monitoring Location \[EX000003.1\] Data Standard when well
information is being exchanged. It includes information about well
ownership, location, use, construction, and where samples or
measurements are made. The user may find that the information here can
be very detailed, however, it should be noted that it provides structure
for those data that are available and there is need to exchange.

  Date             Version    Description

  January 6, 2006  Draft      The Environmental Data Standards Council
                   Standard   agreed to recommend that the Exchange Network
                              Leadership Council publish draft standard in
                              the Federal Register.

**1.3 References**

This standard relies on other standards to make it complete and provide
the necessary support. As such users should consider the Normative
Standards (references) noted below, integral to the Well Information
Data Standard. These include:

-   ESAR: Measure \[EX000010.1\] Data Standard

-   Attached Binary Object \[EX000006.1\] Data Standard

-   ESAR: Monitoring Location \[EX000003.1\] Data Standard

-   Bibliographic Reference \[EX000007.1\] Data Standard

-   Contact Information \[EX000019.2\] Data Standard

-   Representation of Date and Time \[EX000013.1\] Data Standard

**1.4 Terms and Definitions**

None.

**1.5 Implementation**

Users are encouraged to use the XML registry housed on the Exchange
Network Web site
([http://www.exchangenetwork.net](http://www.exchangenetwork.net/)) to
download schema components for the construction of XML schema flows. In
addition, the Environmental Data Registry
(http://[www.epa.gov/edr](http://www.epa.gov/edr)) provides the data
standard structure and attributes in a downloadable format that will
facilitate database development activities.

**1.6 Document Structure**

The structure of this document is briefly described below:

1.  a\. Section 2.0 Well Information Diagram, illustrates the principal
    data groupings contained within Well Information Data Standard.

    b\. Section 3.0 Well Information Data Standards Table, provides
    information on the high and intermediate levels of Well Information
    data groupings, as well as their related data elements. Where
    applicable, for each level of this data standard, a definition, XML
    tag, note(s), example list of values and format are provided. The
    format column lists the required number of characters for the
    associated data element, where "A" specifies alphanumeric, "N"
    designates numeric, "G" is used for grouping and "D" for time and
    date elements.

    c\. Data Element Numbering. For purposes of clarity and to enhance
    understanding of data standard hierarchy and relationships, each
    data group is numerically classified from the primary to the
    elemental level.

    d\. Code and Identifier Metadata: Metadata, defined here as data
    about data or data elements, includes their descriptions and/or any
    needed context setting information required to identify the origin,
    conditions of use, interpretation, or understanding the information
    being exchanged or transferred. (Adapted from ISO/IEC 2382-17:1999
    Information Technology Vocabulary---Part 17: Databases 17.06.05
    metadata). Based on the business need, additional metadata may be
    required to sufficiently describe an identifier or a code. A note
    regarding this additional metadata is included in the notes column
    for identifier and code elements. Additional metadata for
    identifiers may include:

```{=html}
<!-- -->
```
1.  • Identifier Context, which identifies the source or data system
    that created or defined the identifier

```{=html}
<!-- -->
```
5.  Additional metadata for codes may include:

    1.  • Code List Identifier, which is a standardized reference to the
        context or source of the set of codes

        • Code List Version Identifier, which identifies the particular
        version of the set of codes.

        • Code List Version Agency Identifier, which identifies the
        agency responsible for maintaining the set of codes

        • Code List Name, which describes the corresponding name for
        which the code represents

    e\. Appendix A, Well Information Data Structure Diagram illustrates
    the hierarchical classification of the Well Information data
    standard. This diagram enables business and technical users of this
    standard to quickly understand its general content and complexity.
    Appendix B, lists the references for Well Information Data Standard.

**2.13 Well Intervals**

Definition: Well intervals are repeating items that are used to describe
the well from the surface to the Well Hole Total Depth and/or Well
Completion Depth. The interval types include Borehole, Casing, Opening,
Fill, and Lithology. Use as many interval types and intervals for a well
as necessary.

Relationships: None.

Notes: None.

**3.0 Well Measuring Point**

Definition: Characteristics of the well measuring point. The measuring
point is the place from which the measurement is made.

Relationships: None.

Notes: While most wells only have one measuring point, some have two or
more for various reasons. Sometimes an old measuring point can no longer
be used and a new one must be established. Other times, different groups
measuring the same well might establish their own measuring points.
