the
Environmental
Data
Standards
Council
(
EDSC).

The
Environmental
Data
Standards
Council
(
EDSC)
is
a
partnership
among
EPA,
States
and
Tribal
partners
to
develop
and
agree
upon
data
standards
for
environmental
information
collection
and
exchange.

Foreword
The
Environmental
Data
Standards
Council
identifies,
prioritizes
and
pursues
the
creation
of
data
standards
for
those
areas
where
information
exchange
standards
will
provide
the
most
value
in
achieving
environmental
results.
The
Council
involves
Tribes
and
Tribal
Nations,
state
and
federal
agencies
in
the
development
of
the
standards
and
then
provides
the
draft
materials
for
general
review.
Business
groups,
non­
governmental
organizations,
and
other
interested
parties
may
then
provide
input
and
comment
for
Council
consideration
and
standard
finalization.
Draft
and
final
standards
are

INTRODUCTION
The
Compositing
Activity
Data
Standard
describes
data
elements
and
data
groupings
that
are
used
to
exchange
Compositing
Activity
data
and
information.
This
standard
is
only
used
in
conjunction
with
Environmental
Sampling,
Analysis
and
Results
(
ESAR):
Field
Activity
and/
or
ESAR
Laboratory
Components.

1.1
Scope
This
standard
provides
and
describes
data
groupings
that
are
used
to
catalogue
and
exchange
compositing
activity
data.
This
standard
is
only
used
in
conjunction
with
ESAR
Field
Activity
and/
or
ESAR
Laboratory
Components.

1.2
References
to
Other
Data
Standards
This
standard
relies
on
other
standards
to
make
it
complete
and
provide
the
necessary
support.
As
such
users
should
consider
the
references
to
other
data
standards
noted
below
as
integral
to
the
Compositing
