                                 PREFACE
     The Environmental Protection Agency is responsible for receiving and
analyzing an  enormous quantity of  environmental monitoring data  each
year.  Much of this data is delivered in the form of analytical laboratory
results arising from the measurement  of pollutants contained in samples
taken from the environment.  The sheer volume  and diversity of this data
has resulted  in  the need for  EPA to  utilize  Automatic Data Processing
(ADP) technologies to assist in the data gathering and analysis process.
In order to  fully  realize  the  benefits of modem  ADP  technology,  it has
become necessary to develop a standard  approach  for the delivery  of
monitoring data to the Agency.  This document describes the philosophy and
technical details of this information standard.

     EPA plans to  implement  and make available the appropriate computer
software programs for the generation,  receipt,  validation,  and subsequent
processing of information conforming to this standard and its successors,
as updates are needed.  At  the present time,  several  tasks are underway
to develop and install ADP  systems in laboratories to generate the data
formats conforming to the standard. Work is also underway at the Agency's
data center, for developing a means of automated input of data conforming
to the  standard into Agency  databases.    It  is  anticipated  that  this
standard automated  approach  will  be  extended to virtually all  of the
Agency's monitoring efforts within the next few years.

                         Background and Overview
     Since its  creation,  the  Environmental  Protection Agency has  been
directly and indirectly involved in the collection, storage, and analysis
of enviromental measurements  data, under  virtually all of the enabling
legislation.  This prograrmatic area,  broadly referred to as "monitoring",
has been  conducted  inhouse and managed under contract  widely throughout
the Agency,  across  all environmental media, analytical techniques,  and
parameters of measurement.  Direct monitoring involvement  is carried out
by various inhouse  sampling and analysis activities, assisted by Agency
service laboratories, in Regional, Research, and Program offices.  Direct
activity is  also managed  under  a number  of large contract laboratory
programs whose annual costs to the agency total over $30 million.  Indirect
activities are conducted under the permits and compliance monitoring pro-
grams which  require industries,  states,  and municipalities  to provide
environmental measurements data.  Throughout all of these activities, the
Automatic Data Processing (ADP) resources of the Agency have been utili-
zed to assist  in the  storage and analysis  of environmental monitoring
data.

     Before the mid 1970's,  the EPA monitoring program consisted mostly of
inhouse sampling  and analysis activities  involving only  a  few hundred
different parameters of measurement,  principally taken from air and water
media.  The  limited number of  measurement parameters  and organizations
involved in  the  monitoring effort  during  this  era   contributed to  a
straightforward, if not simplistic, approach to data collection, storage,
and quality  control.   Although the Agency  initiated a  few ADP projects
aimed at  automating  laboratory   data collection,  the   majority  of  the
related ADP effort was concentrated on the development and maintenance of
large-scale finished data repositories  such as STORET,  and SARQAD.   The
vast majority  of monitoring data was hand-copied from inhouse  service
laboratory notebooks to reporting  sheets which were subsequently sent to
laboratory service requestors for  further analysis  and storage.  A portion
of the monitoring data was sent from service laboratories to Regional ADP
units which managed its keypunching  and batch transmission to the large-
scale finished data repositories.   Permits and compliance monitoring data
was similarly collected from the  states,  industries,  and municipalities,
with subsequent keypunching for batch transmission to  appropriate large-
scale databases.   For  a  small  portion  of  the   data,   machine-readable
formats were available as an  option,  such  as for  states  furnishing air
quality monitoring data to the national air database,  SARQAD.  Throughout
this timeframe, however, the characteristics of environmental data hand-
ling included many  opportunities  for  errors and long delay times as the
data was  re-copied  and passed in hand  written form  among  the  several
individuals and groups  involved.   Many of the  organizations responsible
for handling the data were considerably removed from the  field sampling and
laboratory analytical processes,  thus increasing the chance for error in
data entry and processing.

     Since the mid-1970's,  the environmental  monitoring requirements im-
posed upon EPA have greatly increased.  This has been due to new enabling
                                   VII

-------
legislation and  regulatory  responsibilites involving  vastly  increased
numbers of measurement parameters,  sampling sites, and media types from
which samples are to be taken.  The enabling legislation has provided for
a number of  different sources of approval  of  environmental sampling and
analytical laboratory methodology within the Agency, with no requirement
to develop commonality or avoid duplication.  New data reporting require-
ments were  introduced as  a  result  of the mandatory Quality Assurance
order of  1979.   The  typical  environmental sample is now analyzed  for
hundreds of  organic  compounds at a cost of  over ?700,   compared to the
previous decade when  samples were quickly analyzed for a few parameters
at one tenth the cost.  In order to meet the vastly increased requirement
for analytical  laboratory processing,  resources  have  been shifted  to
contract laboratory programs  which  account for  over 90% of  the current
EPA total analytical service laboratory program in monitoring activities.

     Automatic Data Processing  (ADP)  systems  have not been successfully
adapted to meet  the  greater information demands  indicated above.  There
has been  no noticable  improvement in  the manner in which handwritten
finished data is supplied to the Agency for review, validation, and input
to the national data  systems.   Current  requirements for  delivery of data
from the  Superfund Office  of Emergency and  Remedial Response  Contract
laboratory Program general organics and dioxin projects alone will result
in the delivery of a  2 1/4 - inch  stack of hand-copied paper reports (3
copies of a  3/4-inch  stack)  for each of the 40,000  estimated samples to
be analyzed in the next year.  The result will be a  stack of 1 1/2 miles
of paper to  be  reviewed by the Agency  in  the next year  alone 1   Without
ADP assistance,  this will be a very difficult task  to carry out.  Although
a number of "one-time" ADP systems have been built for entry and analysis
of monitoring data from  specific projects (e.g.  the temporary systems
built for the Office  of Research  and Development Love Canal monitoring
project), there is presently no Agency standard system  or approach  for
this function.

     In 1983, an ADP project was initiated to standardize  EPA's monitoring
data elements and to capture the information in machine-readable form for
input to Agency data  systems.   Hie  Superfund  Contract Laboratory Program
was identified as the  initial client office for the production implementa-
tion of this project.   As a part of the initial phase of the project,  it
was decided to establish a long term Agency commitment to obtain monitoring
data for processing in standard machine-readable form(s)  at the earliest
possible point in the  finished data  processing  cycle,  for electronic
transmission and  entry  into the appropriate mainframe databases.   It  is
necessary that this effort have a minimal  impact on changes to the design
and the operation of the existing Agency mainframe data systems.   Through
a "standard transmission format" approach,  it  is possible to realize the
benefits of  automation  without  the need  to  modify mainframe  database
software systems.  To assure  these and  other  project   goals,  Computer
Services and Systems Division, Cincinnati,  was charged with the long term
responsibility of maintaining the standard and assisting  Agency mainframe
monitoring database ADP  support personnel   in  its installation,  testing,
and maintenance.    In  addition,  the Office  of Research and Development,
                                   viii

-------
OMSQA. - EMSL - Cincinnati  was assigned a lead role in the implementation
efforts for software  in laboratory instruments to produce  datasets that
meet the  standard  transmission  format.  Throughout  the  project,  the
overall philosophy and goals have been the following:

     1.  Provide a  single,  flexible  information standard  and  efficient
         software that will  optimally meet Agency monitoring  needs,  with
         minimal changes to existing mainframe data systems.

     2.  Capture the data in the  field or laboratory in machine-readable
         form at the  earliest possible point, preferably without having
         to be manually re-entered  or  re-copied if  it is  already  in
         machine-readable form (e.g. on disc in a laboratory data system).

     3.  Capture data that  must be manually  entered only  once,  without
         repetitive entry.    Enter this data  at  the  location and  by the
         person most knowledgeable as to its correctness.

     4.  Conduct software development  necessary to meet the goals of the
         project, starting with the most cost-beneficial data paths.  All
         software is to be developed  in the public domain and maintained
         by EPA to not be vendor specific.  It  can therefore be implemented
         by all institutions and  instrument vendors  that supply environ-
         mental analytical results to EPA.  Laboratories and other insti-
         tutions who will be required to meet the standard data deliver-
         able format  can  either  use  EPA-developed software  for  this
         purpose, or develop their own.

     5.  The information standard and related software  will  be flexible
         in that they can  be adapted to future needs,  with the addition
         of new record  and data types  as these  needs arise.   We expect
         that annual updates will be required, although table entries can
         be changed at anytime to meet individual program needs.

    6.  Avoid the transmission  of redundant  data, i.e.  data  that can be
        reported by a specific  calculation   or  formula involving other
        data elements in the standard.

    7.  The standard is to be capable of handling any environmental para-
        meter,  in any media,  for  any method of analysis.   It is also to
        handle the necessary delineation for analytical quality control
        determinations based  on standard  statistical control  charts  as
        well as  other  program-specific  AQC  requirements  and  methods.

    8.  The initial   software  to  meet the  standard  will  support  data
        transfer on industry standard  9-track magnetic tape.   The standard
        is, however,  data media independent, and the Agency nay subsequen-
        tly allow delivery  via other vendor-independent means,  such  as
        floppy disc,  or direct telecommunications.

-------
     The material  in this document  ccnprises the  proposed initial  EPA
standard for environmental monitoring data transmission  in the following
hierarchy of levels:

     1.  An industry-wide standard for medium of delivery:  Magnetic Tape.
         A checksum  and  record  sequence  numbering  scheme  allows  for
         future use  of  direct  (e.g.   telecommunications)  transmission
         through a "noisy" medium with full error recognition and control.

     2.  An EPA-wide standard for file  formats and physical data record-
         ing methods on the standard medium,  to allow the tape to be read
         by almost  all  Agency  mini  and  mainframe  computer  systems.

     3.  An EPA-wide standard  for  record formats  of records  contained
         within the files.

     4.  An EPA-wide standard for data elements contained within the re-
         cords.  The  standard  includes  data  element definitions  which
         will be used as edit and validation  criteria by the input soft-
         ware.

     It is proposed that this standard be  adopted  and programmed for use
during the next eighteen  months of  alpha and beta testing on  an Agency-
wide basis.  Alpha testing will  be  performed under  the  upcoming Dioxin
IFB, with a limited  number of participating  contract laboratories.   Beta
testing is planned to be performed under a larger  set of Dioxin ZFB labs
as well as  under the upcoming  General  Qrganics IFB  and  perhaps the up-
coming Inorganics  IFB.  Changes and refinements can  be  incorporated for
future releases of the standard  and the supporting computer software, on a
regular basis  after the  first  system is proven  and running.   Please

          Format for Analytical Results Reports on Magnetic Tape


Introduction

This paper proposes an EPA  standard for media (magnetic tape) and record
formats to be used in transmission  of analytical results.   The following
points should be noted:

     1.  The standard describes transmission formats only.  It is expected
         that processing  systems will  convert  the  input records  into
         forms more convenient for storage and processing.

     2.  Record types 1  through 6  are currently being used  in existing
         major Agency applications.  Therefore,  these  formats are  not
         subject to  revision.   Record  type  7  provides flexibility  for
         varying needs of different  applications.   Record type 8 is  a
         tentative addition to the standard.

     3.  Spaces between   fields  permit these records  to be  prepared by
         programs written for  laboratory automation systems  in versions
         of BASIC which require this feature, as well as to be compatible
         with Agency standard statistical and database management systems
         (e.g. SAS, S2K,  ADABAS, etc.).

     4.  Record formats are consistent with requirements for a future er-
         ror-free telecommunications format.

Tape Format

     1.  Tapes shall be  industry - standard  9-track,  800  (NRZI) or 1600
         (PE) bits per inch, with no internal labels.

     2.  Records shall be fixed-length 80-byte records  consisting of ASCII
         characters.  If  the  operating  system  producing the  record  re-
         quires an end-of-record code  (such  as carriage  return or line
         feed), this  code shall occupy record  position 80.   Otherwise,
         position 80 shall be blank.

     3.  Records may optionally be combined into fixed-length blocks, with
         a blocksize not exceeding 4000 bytes.  If the block includes a
         prefix or postfix  supplied by the  operating  system in addition
         to the records,  information about the presence and length of the
         prefix or  postfix  shall  be  included  in the external label.

     4.  Records shall be in the formats specified in Exhibits  1  through 6.

     5.  Tapes shall consist  of one or more  files.  Each  file shall end
         with a tapenark.   The last file on  the tape  shall end with two
         tapenarks.

-------
     6.  Each tape reel  shall  bear one or more  external  labels,  collec-
         tively supplying the following information:  volume ID, density,
         blocksize,  recordsize,  decimal  value  of character  in  record
         position 80, number of files,  creation date, and name,  address
         and phone number of submitter.   Individual Agency environmental
         monitoring programs may require  additional external labels such
         as to provide linkage to other related data (e.g. field sampling
         data sheets or lab "chronicles").

Record Formats

There are eight record types  in the standard, with the formats shown in
Exhibits 1 to 6:

-------
Analysis Types

The standard divides all analytical procedures into two types:

     1.  Singles - one aliquot of a sample produces one analytical result.
                   Record types  1 and 2 are mandatory; other  types  are
                   optional.  Analytes are  identified by parneth codes.
                   Examples:  Single  -  channel continuous  flow analyzer
                   and single analyte atomic absorption methods.

     2.  Multiples -  one aliquot of a sample produces more than one ana-
                     lytical result.  Record types 1,  2 and 6 are manda-
                     tory; other  types  are  optional.   Record type  6,
                     representing the  sample,  contains a  parmeth  code
                     which acts as  an identifying label for  the  list of
                     compounds analyzed.  Record  type 2,  representing an
                     individual analyte, contains either a parmeth code
                     or a CAS code  (organ!cs)  and an  indicator  ("P" or
                      "C") as  to  which code was used.   The  two  codes  may
                     not be mixed in one  run.   Examples:   Multi-channel
                     continuous flow  analyzer,  QC/MS, and  ICAP methods.

It should be noted that records which are optional in the standard may be
considered mandatory  in a  given application  (e.g. Contract Lab Program,
Effluent Guidelines Program).

Production Runs

Since, under the proposed  standard, a file contains  the  results  for one
production run,  it is  necessary  to define  a .run  in terms applicable
across a wide  variety of analysis  types.   In general, a run should re-
present a "group" or "batch" of samples that are processed in  a continuous
sequence under relatively stable conditions.   Specific points character-
izing a run are:

     0 Calibration - initial and continuing checks.  Typically all samples
                     in a run use the same calibration data.  (There will
                     be a few exceptions,   such as isotope  dilution  for
                     GC/MS, where  some  of the calibration information is
                     contained in each sample.)

     0 Instrument conditions  -  are typically constant  throughout a run.
                               Results obtained on different instruments
                               cannot be combined in one run.

     0 Parmeth code -  (see Appendix Bl).  XXX will be constant.  Y, Z and
                      MN will often be constants, but are not required to
                      be.  The  amount of variation allowed here differs
                      with the nature of the analytical procedure.

The time span  of a run varies with the type  of analysis.   Many runs for
inorganic analyses take a fraction  of a day.  Some organic analyses, such

-------
as GC and GC/MS,  take a long tine  for  each sanple, so that the run may
contain data from several work shifts.

The first record in each tape file must be record type 1,  the Run Header.
Positions 3-22 form an identifier for the  run.  After  removal  of blanks,
this would  read  8404011521GC/MS  for a GC/Ms  run  started at 3:21p.m.  on
April 1, 1984.  The measurement type  is general, and will  be assigned by
EPA.  Similarly,  the parmeth code in record type 1 is a generic represen-
tation of the parmeth codes in the  run, and will have  zeros in any of Y,
Z and MN  if there are variations.    In  runs  completed during  one  work
shift by one individual, the  initials designate the responsible  analyst.
For runs which involve  more than  one  instrument  operator,  it may  be
necessary to use  the initials of a manager.   In any  case,  the  initials
should indicate one  individual responsible for the quality and consis-
tency of the entire run.

Record Sequence

     1.  A Run Header (type 1) record must be present as the first record
         in the file.   Further occurrences of  the  type 1  record in the
         file are not allowed.

     2.  In "singles" runs  each type 2 record represents a sample.  Record
         types 2  (and  3 if present)  should occur in the  order  in which
         analytical results were obtained.  The  type 2 records for quality
         control items have  further  rules  (see Appendix  B, Exhibit B2,
         for definitions of QC types):

         a.   LD1 must occur before  the corresponding LD2 record, but the
             two records need not be adjacent.  (Similar rule for FD1 and
             FD2)

         b.   LCK must occur before  the  corresponding LD2  record and LSF/
             LSA record pair,  but  the  records need  not  be  adjacent.

         c.   LSO must occur before  the  LSF/LSA record pair, but the re-
             cords need  not  be  adjacent.   (Similar  rule  for  FSO and
             FSF/FSA)

         d.   LSD must  occur before the LF1/LSA record pair,  which  must
             occur before the LF2/LSA record  pair,  but the records  need
             not be adjacent.

         e.   In all cases,  a record pair must be adjacent.   In each case,
             the first  record of the pair represents  an actual  measure-
             ment, while the  second  holds a known concentration  value
             supplied by the analyst:

             LSF laboratory spike - final
             LSA amount added

             LCM laboratory control standard
             LCT theoretical concentration of standard

                                    4

-------
             LSI surrogate spike - final concentration
             LS2 amount added

             LFM laboratory fortified blank
             LET theoretical concentration of fortified blank

             LF1 laboratory spike-final - first member
             LSA amount added

             LF2 laboratory spike-final - second member
             ISA amount added

             FSF field spike-final
             FSA amount added

             PCM field control standard
             FCT theoretical concentration of standard

             FRM field reference standard-measured
             FRC field reference standard-certified

             FFM field fortified blank
             FFT theoretical concentration of fortified blank

     3.  In "multiple results" runs,  each unknown or quality control sam-
         ple is represented by a group composed of a type 6 record,  which
         holds samplelevel information, followed by one type 2 record for
         each analyte.  The QCC field of the type  6 record holds a  count
         for the number  of analytes being determined.   Record pairs for
         surrogate spikes  (LS1/LS2) may  occur anywhere within the  group
         after the type  6 record, but are not  included in  the analyte
         count for the sample.  The  placement rules  shown  for singles
         apply, except that each sample is now represented by a  group of
         records, instead of one record.

     4.  Type 4 records, holding quality control limits which were in ef-
         fect during the run, may  follow the type  2 QC record (or record
         pair), or may be grouped at the end  of  the run  results  file.
         The latter is preferable.

     5.  Type 7  records may  be defined to occupy any position except be-
         fore the type  1  (header)  record or  between the two  records of
         the pairs listed above in 2e.

     6.  Type 8  records,  holding method detection  limits  for compounds,
         may be inserted after the type 2 record to which they relate, or
         nay be grouped at the end of the run results file, following the
         grouped type 4 records.  The latter is preferable.

Dates and Times

Wherever a date  or time-of-day is required, the  information consists of
successive groups of two decimal digits each, separated by blanks.  Dates
are given in the order YY MM DD,  and times  as HH MM.  Since some computers
generating the  date  and time  sequence  may  have difficulty  producing
leading zeros,  these will  not be  required on the  tape.   The  program
reading the tape will convert leading blanks to leading zeros in all date
and time fields.

                                    Appendix A

                             of Definitions for Type 7 Records

The following 16 formats have been proposed to provide additional information to
meet the needs of specific Agency programs.

The relative positions of these records in the file nay be summarized as follows:

Follows Type             Record Descriptors             Information On

 1                       001, 005, 006, 007, 010,       Run (group, batch, etc.)
                         Oil, 012, 013, 014, 015

 2 (singles) or          003, 004, 008, 009,            Sample
 6 (multiples)           016

 2                       002, 008, 010                  Analyte

 1, 2 or 6               000                            Run, sample, analyte
                                                        (comments)

No relative positioning is specified where multiple type 7 records follow, for
example, one type 2 record in a singles run.  This should be dictated by the
logic of the program which prepares the tape records.

Type 7 records may be regarded as "trailer" records, supplying additional
information for the type 1, 2 or 6 record they follow.  All type 7 records
encountered refer to the closest preceding type 1, 2 or 6 record, until another
type 2 or 6 record is encountered.  (In the case of record pairs, type 7's follow
the second member of the pair, but will normally refer to the first member, which
represents an actual measurement.)

                 STRUCTURE OF THE PARAMETER/METHOD (PARMETH)  CODE

The Parmeth Code

The parameter/method (parmeth) code is a seven character alphanumeric code that is
utilized in the  Agency laboratory  Data  Management System.  The purpose of  the
parmeth code is to define concisely the target analytes, the details of the method
of analysis, and the  sample medium which  was the subject of the analysis.   The
parmeth code has the form:
     XXXYZMN
Where:

     XXXN     defines one or more target analytes plus the analytical method.
              This part of the code  is  identical with the method numbers defined
              in EPA methods manuals  (1)  and the Federal Register  (2)  for water
              methods.  If N is not specified, the default value is one.   The XXXN
              part of the code is always numeric.

      Y      is an alphanumeric modifier which specifies that an allowed option in
             the method has been implemented, or specifies fractions of analytes
             in the method.  The  defined values of Y are  dependent on  the value
             of XXXN, that is, a  Y =  5  in the  200 series  methods may  have  a
             different meaning than  Y  = 5  in the  300 series  methods.   As  an
             example, Y may  distinguish total and dissolved  phosphorus measured
             by the same method but with or without the  optional method filtra-
             tion.  Another example  is  the  use of Y to distinguish the acid  and
             base/neutral fractions  in method  625.   If  Y is  not defined in  a
             method, the default value is one.

      Z      is a code to define the environmental medium to which the analysis
             was applied, for example, drinking water or ambient air.  The Z part
             of the code is alphanumeric.

      M      is a numeric code to allow variations in the method that may be ne-
             cessary for local needs.  The M may be used, for example, to distin-
             guish data  from two  similar or  identical instruments  running  the
             same method in  a  high production laboratory.   One instrument may be
             M =  1  and  the other M =  2.  This digit nay also be used  to define
             analytes in addition  to those defined by XXXN.   local  users are  re-
             quested to use M = 0, 1, 2,  3,  or 4 when M is defined in connection
             with an  officially promulgated XXXN method.  Purely  local methods
             are M = 5-8, and M =  9 is reserved for other future uses.

The parmeth code is validated as numeric  for XXX and MN and as alphanumeric for Y
and Z.   It is stored right justified in the  9 digit specific parameter code field.

               LIST OF RESULT QUALIFIERS

A result qualifier (also called a non-numeric result-see Exhibit 2A)
consists of  3  alphanumeric characters which act as an indicator of
the fact and the reason that the subject analysis (a) did not produce
a numerical result,  (b) produced a numeric result taut it is qualified
in seme  respect relating  to the validity  of the  result,  or  (c)
produced a numeric result  but for administrative reasons  is not to
be reported  outside  the laboratory.   Qualifiers related  to  STORET
remarks are indicated in the list below.

           Definition

There was not a sufficient concen-
tration of  the  parameter  in the
sample to exceed the lower detec-
tion limit  in force  at  the  time
the analysis  was performed.   (No
result; STORET "W" remark)

A preliminary screening of the sam-
ple for the  subject parameter was
conducted.  The result of the
screening indicated that  it would
not be  useful  to  determine  the
concentration of the parameter.
(No result; no STORET remark)

There was not a sufficient quantity
of the sample to conduct an analy-
sis to determine the concentration
of the subject parameter.  (No re-
sult; no STORET remark)

There was an accident in the labora-
tory that either destroyed the sam-
ple or rendered it not suitable for
analysis.  (No result;  STORET "O"
remark)

There was an accident in the field
that either  destroyed  the  sample
or rendered  it  not  suitable  for
analysis.  (No results;  no STORET
remark)

Due to improper preservation of the
sample it was rendered not suitable
for analysis. (No results; no STORET
remark code)

             Suggested Parmeth Codes for Dioxin and General Qrganics


The parmeth codes in Table C-l  are suggested  for use with the CLP and BCD programs
for dioxin and general organics.  In all of these, the Z position should be inter-
preted with the  aid of  Exhibit B4.  The generic value  of 1, which  represents
"water, type unknown or not specified", is used for water analysis.  Each of these
generic parmeth  codes  represents a group of specific codes, with Z values of 2
through 9, A or R.

Solid samples are represented  by two  specific codes, with Z values  of G (bottom
sediment or deposit) and H (soil).

Dioxin rinsate samples use the value of Q (field sampling equipment solvent wash-
ings ).

The methods used by EGD  are shown  for water only.   The list can be expanded to
other matrix values if appropriate.

Each parmeth code shewn  occurs in  a type  6 record and acts as the header for the
appropriate list of organic  compounds,  as given in  the Federal Register for the
method shown  in  the definition  column.    If an additional  list of tentatively
identified compounds is to be reported for a given sample, a second type 6 record
is used,  with a  different parmeth code.   This  record  represents  a  different
analysis on the sample, and is followed by type  2  records for each of the tenta-
tively identified compounds.
