            DATA STANDARDS FOR THE ELECTRONIC TRANSMISSION OF
                      LABORATORY MEASUREMENT RESULTS
PA Form 131 5-12A (5-86)
1.   PURPOSE.   The purpose of this Order is to issue standards
    for the electronic transmission of environmental measurement
    results from laboratories to EPA programs.  These standards
    will provide a consistent definition of laboratory data and
    will facilitate cross-media use of laboratory data.

2.   SCOPE.   This Order applies to laboratories that supply
    measurement data for Agency, Regional or program office
    decisions.

3.   BACKGROUND.

      a.  Integration of information and databases is difficult
          because program offices use disparate formats and names
          for similar data elements.

      b.  There is a need to make and support decisions based on
          standard information and data collected which cut across
          the Agency's programs.

      c.  Specific programs have an increasing need to share data
          from other programs, other Agencies, States and local
          governments.  This adds credence to the need for accept-
          able data standards to facilitate the exchange of
          information.

      d.  Information technology has reached a point at which the
          sharing of data among automated systems is technically
          feasible.

      e.  The Agency has implemented standards for hardware and
          software which facilitate the sharing of data among
          programs.

      f.  Laboratory measurement results are commonly acquired by
          almost all the operating programs and Regions.

                                                        12/10/87


      g.  The large quantity of data that is received from
          laboratories mandates the use of automated systems of
          transmission to decrease errors of transcription, to
          increase the speed of reporting and to facilitate wide
          use of the data.

      h.  A standard approach to the transmission of laboratory
          data is required to ensure that all measurement data
          reported to Agency programs from laboratories will
          include common elements that define the sample type,
          the measurement technique and method, and the quality
          of the measurement, .in addition to the measurement
          results.

      i.  These standards define data originally acquired for
          one specific purpose to other potential users.  Use of
          these standards certifies the existence of qualifying
          information to second and third party users of the data.

4.  AUTHORITIES.

      a.  15 CFR, Part 6 Subtitle A, Standardization of Data
          Elements and Representations.

      b.  OMB Circular A-130, Management of Federal Information
          Resources.

5.  POLICY.  The Standards for Electronic Transmission of Laboratory
    Measurement Results in Appendices A through C to this Order
    will be used to move measurement results from laboratories to
    program offices.

      a.  Programs will adhere to the standards except where it
          can be demonstrated that the costs of using the standards
          exceed the benefits or will impede the Agency in
          accomplishing its mission.

      b.  These standards provide a framework that can be adapted
          to the needs of each program.  Addition or deletion of
          data elements is permissible within the standards.

      c.  No timetables are set for conversion of existing automated
          data transfer mechanisms.  The Office of Information
          Resources Management will ensure that new instances
          of the automated collection of laboratory measurement
          results will consider these standards as part of the
          workplan.

6.  ASSISTANCE.   Assistance in implementing this Order can
    be obtained  from the Immediate Office,  Office of Information
    Resources Management (OIRM).

7.  PROVISION FOR WAIVER.   OIRM recognizes  that due to variances
    in mission needs,  information requirements, and resource
    allocations,  not all information systems can easily conform to
    the standards defined  in this policy.  In order to provide a
    reasonable amount  of flexibility, this  provision for waiver
    is included  in the Order.

      a.   An application for waiver should  provide information to
          substantiate the problems encountered in adopting the
          standard.   Also, the application  should include the
          program's  alternate plan of action for transmitting
          laboratory results.

      b.   The application  must be approved  by the decision official
          in the  requesting office and the  respective Senior
          Information  Resources Management  Official prior to
          submission to the Director of OIRM, who has responsibility
          for final  disposition.   The applying office will be
          notified in  writing of  the disposition of the waiver
          within  30  days.             .

          Format for Analytical Results Reports on Machine Readable Media

Introduction

This constitutes an EPA standard for media 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 pro-
      cessing systems will convert the input records into forms more convenient for
      storage and processing.

  2.  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.).

  3.  Record formats contain sequence numbers and checksums to be consistent with
      requirements for a future error-free telecommunications format.

Media Format

The record formats are intended to be general for a variety of media/ but some
special considerations apply to certain media.

  1.  Magnetic Tapes shall be industry - standard 9-track, 800, 1600, or 6250 bits
      per inch, with no internal labels.  Floppy diskettes shall be IBM-PC compati-
      ble and may be of any standard size.  Telecommunications requirements will
      be defined as appropriate.  Data compression or "squeezing" algorithms will
      be employed where appropriate for future telecommunications protocols.

  2.  Records shall be fixed-length 80-byte records consisting of ASCII characters.
      If the operating system producing the record requires an end-of-record code
      (such as carriage return and/or line feed), this code shall occupy record
      positions 79-80.  Otherwise, positions 79-80 shall be blank.

  3.  Records on tape may be combined optionally into fixed-length blocks, with a
      blocksize not exceeding 4000 bytes.  If the block includes a prefix or post-
      fix 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.  Tapes or diskettes shall consist of one or more files.  Each tape file shall
      end with a tapemark; the last file on the tape shall end with two tapemarks.
      Diskettes shall have all files present in the root or parent directory.

  5.  Each tape reel or diskette shall bear one or more external labels, collec-
      tively supplying the following information:  volume ID, number of files,
      creation date, and name, address and phone number of submitter.  Magnetic
      tape labels shall also contain density, blocksize and recordsize.  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").

                                                                   12/10/87
  6.  The following media  shall be compliant with Federal Information Processing
      Standards  (FIPS) cited below:

         FIPS                             Subject

          3                               800 BPI, NRZI, 9-track tape
         25                               1600 BPI, PE, 9-track tape
         50                               6250 BPI, GCR, 9-track tape

Record Formats

There are six groups of  record types in the standard, as shown below.  Detailed
record formats follow.

Type     Name                Contents

 10      Run Header          Contains information pertinent to the whole production
                             run  (group, batch, etc. of samples or sample equiva-
                             lents) .  See production run definition below.

 20      Sample  Header       Contains sample-identifying information or corres-
                             ponding information for calibrations, QC samples,
                             instrument performance checks, etc.

 30      Results Record      Contains any final result on a sample, calibration or
                             QC sample and identifying information.

 40      Deleted Record      Signals a deleted record; record contents are unde-
                             fined except for the record type code.

 50      Special Record      Signals a header for other Agency Standard Data Base
                             Records  (e.g., STORET, SAROAD, SFC, AIRS, etc.).

 90      Comments Record    Signals a record containing free-form comments.

Record types 10, 20 and  30 are mandatory, except when field sampling data only are
being reported,  in which case type 30 may be missing; other types are optional.
Type 20, representing the  sample, contains a Region and Sample ID which acts as an
identifying label for the  sample.  The QC code indicates whether the data are from
an environmental sample, calibration or QC sample; or other calculated run-wide
data such as mean response factors.  Type 30, representing an individual analyte,
contains either  a program  or contract specified identifier or a CAS code and an
indicator ("I" or "C" or another code) as to which code was used.  Type 50 is used
to include data  from any other standard agency data base such as STORET or AIRS.
It is required only when records from these other systems are being mixed with
records from this standard.  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).  See page C-5  for an example of the sequence of the record types.

Production Runs

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

                                        A-2

-------
                                                                   Appendix  A
                                                                   12/10/87

   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 calibra-
                   tion information is contained in each sample.)

   0 Method number - (see Appendix B) will be constant.

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

The time span of a production 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 time for each sample, so that the production run may contain
data from many work shifts which could span days or weeks.

The first record in each file must be a record type 10, the Run Header.  Positions
4-24 form an identifier for the run.  Ignoring the blanks, this would read
118404011521GC/MS " for a GC/MS run started at 3:21 p.m. on April 1, 1984.  If data
from a single production run are split and reported on several files (presumably at
different times), it is mandatory that this run identifier be identical on each
such file.  The measurement type is general and will be assigned by EPA.  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 consistency of the
entire run.

Record'Sequence   (see page C-5)

   1. A Run Header (type 10) record must be present <*.=> the first record in the
      file.  Further occurrences of the type 10 record in the file are not allowed.

   2. Each environmental sample, calibration or quality control sample is
      represented by a group composed of a type 20 and 21 record, which holds
      sample level identifying information, followed by one type 30 record for
      each method analyte or standard.  The region/client and EPA sample ID together
      should uniquely identify a single sample, but there is no separate requirement
      that the sample ID be unique on a national level.  The type 20 record holds
      a count for the number of method analytes being determined.  Type 20 records
      should occur in the order in which analytical results were obtained.   The
      type 20 records for quality control items have further rules (see Appendix B,
      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.   LF1 must occur before the corresponding LF2 record, but the records need
          not be adjacent.

      In  addition, a type 20 record is used as a header for any additional run-wide
      data that must be reported for each method analyte (such as detection limits
      or  interelement correction factors).  Unique identifiers given on page B-6
      are used in place of "QC codes" to indicate the types of data that follow.

   3. Type  50  records  are  used to  indicate the presence of data in formats of other
      existing agency  data bases and may occupy any position.  Each contains a
      counter  to  indicate  the number of records from the other system that follow.

   4. Type  90  records  may  be  defined to occupy any position except before the type
      10  (header)  record,  or  between records following a type 50.


File/Record Integrity

All record  types  (excepting those  following type 50) shall contain the following
check fields to ensure file and record integrity:

Record       Field      Field
Position     Length      Contents                       Remarks

72-74           3         Record sequence number         000-999, repeated as
                         within file                    necessary

                                                       calculation algorithm to
                                                       be supplied

79-80           2         Reserved for operating         Will contain blanks, or
                         system use                     a code for CR and/or LF


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.  All hours will be given as 0 to 23,  right
justified,  using a 24  hour clock and will be local time.  Since some computers
generating  the date and time  sequence may have difficulty producing leading zeros,
these will  not  be  required.   The program reading the file will convert leading
blanks to leading  zeros in all date and time fields.

Necessary Information

The exact list of  reportable  information will obviously vary considerably from one
program to  another.  The information given on the following records is designed to
be as general  as possible,  and not all of it will apply to any program or method.
It is important to note that  this standard is in no way attempting to determine,
or even suggest, what  data should or should not be reported for any given program;
it is only  defining how that  data should be reported.   Any data element that is
not applicable should  simply  be left blank; if no data on a record type are appli-
cable the entire record may be  omitted.  All of the definitions of the field
contents should be considered to be general; specific programs and methods may
further define  any field,  or  may require the use of some fields to represent program
or method specific information.  Additional method dependent record types may be
defined in  the  future  to accommodate information which cannot be reported using the
defined format.

                                                                   Appendix  A
                                                                   12/10/87
Field'Sampling Data
Field sampling data will also be reported using this standard.  If the field
sampling data are sent in separately, then the file will be structured in the same
manner as an analytical analysis.  There will be a type 10 record at the start
which will have "FIELD" in columns 19-23 along with whatever information is
appropriate.  All type 20 records will have the appropriate field GC codes along
with an appropriate sample qualifier, e.g., FLD".  Much of the other information
will be blank.  Type 30 records will be present only if necessary (such as to
report the amount of field spikes for each spiked analyte).  If field sampling
data are reported by the laboratory performing the analysis, using the same file,
it will be necessary to have two type 20 records for each sample, one for the
analytical results and one for field sampling data.

Multiple Volume Data

There is no requirement under this standard that all the data from an entire
production run fit onto a single volume of the transmission medium.  If data are
being split into multiple volumes, then each program will define how this is to be
performed.  For example, if the multiple volumes are reported at different times,
it may be necessary to repeat the transmission of all initial calibration data
with each volume.  Cn the other hand, if multiple volumes are utilized simply
because all data will not fit onto a 360 K diskette, then there would be no need
to repeat the initial calibration data on each volume.  In all cases, the program
will define when and where data may be split and how the files are to be named so
that the sequence is unambiguous.  What is necessary, is that all volumes start
with a type 10 record, and that all type 10 records have the same run identifier
as explained on page A-3.  If it is necessary to split the data from a single
sample into multiple volumes, then the type 20 (and following) type records for
that sample must be repeated; in this situation, it is mandatory that columns
4-37, which collectively identify the sample, be identical in each volume.

General Instructions

1.  All character data are to be upper case, except in comment fields where no
    restrictions are given or when using the symbols for chemical elements (one
    upper case letter or one upper case letter followed by a lower case letter).

2.  Missing or unknown values are to be left blank.

3.  All character fields are to be left justified.

4.  All numeric fields are to be right justified.  A decimal point is to be
    used with a non-integer if exponential notation is not used. Commas are not
    allowed.

5.  All temperature fields are in centigrade and are presumed non-negative unless
    preceded by a minus sign (-).

This record is necessary only if records from another system are being mixed with
records from this standard.  The record may appear multiple times if data from more
than one additional system are present, or if all such data are not contiguous.  The
counter will give the number of records in the alternate format that follow.  These
alternative records have no defined format within this standard, and therefore no
check for any contents will be made.  Record types, sequence numbers, and checksums
will not be present in the expected fields, and the sequence number counter will
simply ignore these records.  Processing programs are expected simply to pass these
records as received to the appropriate system.

                           STRUCTURE OF THE METHOD NUMBER
The Method Number
The method number is a five character alphanumeric code.  The purpose of the method
number is to define concisely the target analytes and the details of the method of
analysis.  The method number has the form:

  XXXXY

Where:

  XXXX   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, the code of Federal Regulations and the private standard setting
         organizations, e.g., ASTM.

    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 XXXX, 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 filtration.  Another example is the use of Y to distin-
         guish the acid and base/neutral fractions in method 625.  If Y is not
         defined in a method, the default value is one.

The method number is validated as alphanumeric for XXXX and Y.  It is stored right
justified in the 5 digit method number field.  Appendix C gives examples for
organic and inorganic analyses.

FIELD SPIKED SAMPLE -
FINAL VALUES
                     Definition

An environmental sample which was split in the
field.  The portion represented by FSO is analyzed
according to the analytical method without fortifi-
cation (spiking).

The second portion of the environmental sample
which was split in the field, and to which a spike
was added in the field with a known concentration
increment.  The measurement(s) of the final concen-
tration(s) was made according to the analytical
method (FSF).
The following QCC values do not refer to actual samples or calibrations for which
laboratory results are obtained.  Instead they are used on type 20 records which
act as a header and indicate  that additional (usually calculated) analyte specific
data will be present on type  30 (and following type) records.  Usually these data
will apply to an entire production run, in which case they will appear immediately
following the type 10 record.  If the data apply to only a portion of the samples
in the run, they should be placed immediately preceding the samples to which they
applies.  Much of the rest of the information in the type 20 record may be blank,
indicating that this data does not apply to these results.  Many of these codes are
method specific, and more codes will be added as additional methods require addi-
ti ^nal data.

            produce a numerical result,  (b) produced  a numeric result but  it is
            qualified in  some respect relating to the type or 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.  This list is not
            intended to be complete/ and it is assumed that individual projects
            will add additional qualifiers to cover project specific circumstances.

            Definition

There was not a sufficient concentration of the
parameter in the sample to exceed the lower
detection limit in force at the time the analy-
sis was performed.  (No result; STORET "W"
remark)  Numeric results field, if present, is
at best, an approximate value.

A preliminary screening of the sample 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 analysis to determine the
concentration of the subject parameter.  (No
result; no STORET remark)

There was an accident in the laboratory that
either destroyed the sample or rendered it not
suitable for analysis.  (No result; STORET "0"
remark)

There was an accident in the field that either
destroyed the sample or rendered it not suit-
able 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)

The subject parameter was present in the sample
but no quantifiable result could be determined.
(No result; STORET "M" remark)

The sample was not analyzed for the subject
parameter, instead it was used as part of a
composite sample.  (No result;  STORET "E"
remark)

            Definition

The analysis results have been rejected for an
unspecified reason by the laboratory.  For any
results where a mean is being determined, this
data was not utilized in the calculation of
the mean.

The indicated environmental sample or calibra-
tion has been split into more than one analy-
sis/ and the analysis results will be reported
as more than one group of results (multiple
type 20 records).

A combination of "SPL" and "RIN"
A combination of "SPL" and "REX"
The subject parameter is being utilized as an
internal standard for other subject parameters
in the sample.  There is no analysis result to
report, although the theoretical and/or limit
value(s) may be present.

A combination of "STD" and "BDL"
Background correction has been applied to this
value.

The subject parameter had a measurable value
above the established QC limit when a blank was
analyzed using the same equipment and analyti-
cal method.  Therefore the reported value may
be erroneous.

The subject parameter has been confirmed using
an auxilliary analytical technique as specified
in the analytical method.

A combination of "TIE" and "FBK"
                          The indicated compound is suspected by the
                          analyst of being a product of an aldol conden-
                          sation reaction.

                          The subject parameter was determined using an
                          alternate measurement method.  Value is
                          believed to be accurate but could be suspect.

                    Exanple Method and Matrix Codes for Dioxin,
                       General Organic and Inorganic Methods


The codes in Tables 1 and 2 are examples of method number designations for dioxin,
general organics and inorganics.   In all of these, the Z position refers to the
matrix code and should be interpreted with the aid of page B-9.   The generic value
of I/ which represents "water, type unknown or not specified",  is used for water
analysis.  Each of these generic matrix codes represents a group of specific codes,
with Z values of 2 through 9, and A through 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 ).

Each method code shown occurs in a type 10 record and acts as the header for the
appropriate list of method analytes.

Method variations are designated by the N position.  For example, Method 613
(Table 1) is run in three variations - full scan, partial scan and high
resolution.

Notes:

     1.  See Page B-l  for the  structure of "XXXX" and  "Y".

     2.  For each water sample,  the appropriate value  of  "Z" should replace the
         generic value of 1.

     3.  The values  of "Z" and "N"  are sample dependent and may vary within a
         production  run. They are  reported  on type 20 and 21  records  (pages A-12
         and A-14).
