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.

Draft
Standard
The
Environmental
Data
Standards
Council
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
(

noted
below,
integral
to
the
Well

Implementation
Users
are
encouraged
to
use
the
XML
registry
housed
on
the
Exchange
Network
Web
site
(
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)
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:

a.
Section
2.0
Well

illustrates
the
principal
data
groupings
contained
within
Well
Information
Data
Standard.

b.
Section
3.0
Well

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

"
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.

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.
