Revision: Office of Water Quality Technical Memorandum 92.06
INTRODUCTION
Over a quarter of a million bottles are sent to the National Water Quality
Laboratory (NWQL) each year for analysis. To ensure the samples arrive safely
and to enable analysts to perform the expected analytical procedures, several
requirements must be met. The NWQL has a number of guidelines that district
personnel are advised to follow when submitting samples o the laboratory.
This NWQL Technical Memorandum is intended to answer current questions and
eliminate some of the problems associated with sample shipment and submittal.
PURPOSE AND SCOPE
This memorandum addresses issues related to the shipment and submittal of
samples sent to the NWQL and also provides instructions for filling out
Analytical Services Request (ASR) forms. This memorandum supersedes Office of
Water Quality Memorandum 92.06 and should now be used as the official
reference for instructions pertaining to sample shipment and submittal.
NOTE: For purposes of this Technical Memorandum, bottles, cartridges, vials,
and other types of sample vessels that are used to collect water, sediment, or
tissue samples will be collectively referred to as "bottles."
PREPARING ANALYTICAL SERVICES REQUEST FORMS (ASR's) FOR SHIPMENT
ASR forms are available at the NWQL at no cost to WRD personnel. The most
recent version of the ASR was developed in 1992, and that version should be
used by all districts not using computer-generated forms. Older versions of
the ASR do not provide sufficient sample information and should
not be used.
NOTE: ASR's must be typed or filled out using a pen with permanent,
waterproof ink.
Felt tip pens MUST NOT be used.
Mandatory Information
The mandatory information is indicated by an asterisk on the ASR. The
mandatory information follows:
station id or unique number
phone number
project chief
state, district/user
project account number
begin date
The Project Chief and Phone Number are essential information in the event of
problems or questions.
District personnel are encouraged to include as much information about the
sample and the bottles as possible on the ASR. It is critical that district
personnel identify all highly contaminated or potentially hazardous samples on
the ASR so that proper precautions can be taken at the NWQL.
Schedules, Field, and Laboratory Codes
Schedules and labcodes required to initiate analytical work must be listed on
the ASR. The schedules and labcodes must be current and valid and can be
verified in the PRIME using the Schedules, Parameters, and Networks (SPN)
program. Some schedules and all labcodes are also listed in the NWQL 1994
Services Catalog (Timme, 1994). Do not attempt to request analytical work by
writing request information on the bottles.
Field codes must be filled out to meet district quality control (QC)
requirements and for storage in the National Water Information System (NWIS).
Sample Medium, Analysis Status, Analysis Source, Hydro Condition, Sample Type,
and Hydro Event are required if analytical results are to be stored in
WATSTORE/NWIS. If the required information is not provided, delivery of
analytical results may be delayed, or data may be sent to BADQW.
Field Values
All fields are optional, but filling in the "Shipped by" and "Phone No."
fields is strongly suggested so that any problems or questions with the sample
can be resolved quickly. Field values for pH and specific conductance are
used to complete the QC checks at the NWQL. Include pH and specific
conductance values for all inorganic samples to ensure that reporting of
analytical results is not delayed because of failed QC caused by missing field
values.
Bottle Types
Complete the bottom part of the ASR with information about the number and type
of bottle sent (see table 1 for Sample Type Definition). More complete
information on sample designations, containers, and treatments is available in
Timme, 1994, p. 17-19. It is strongly recommended that polyethylene bottles
be used for radiochemical or stable isotope samples whenever possible.

OTHER See NWQL catalog for information on other bottle types.
NOTE: Bottles and ASR information must match and be complete in each
container. DO NOT send bottles without ASR's or ASR's without bottles.
* As of January 1, 1995, the FC and RC bottle types on the most current
version of the ASR will no longer be valid. After January 1, 1995,
valid nutrient bottle types will be FCC, RCC, FCA,and RCA.
SHIPPING CONTAINERS
1. Unchilled bottles may be shipped in standard, General Services
Administration (GSA) issue, disposable cardboard boxes. The GSA National Stock
Numbers (NSN's) for three recommended sizes are as follows:
NSN Stock Number Box Dimensions FY-95 Price
NSN 8115-00-183-9505 (6 X 4 X 4) in. $ 6.97 per 25
NSN 8115-01-017-6054 (11.25 X 8.75 X 10) in. $15.32 per 25
NSN 8115-00-079-8682 (14 X 14 X 10) in. $13.72 per 15
2. Ship chilled bottles in coolers that are free of leaks. If the cooler
has a spout, seal it with silicone or epoxy to prevent leaking. Damaged
coolers will not be returned to the district but will be discarded following
notification of district personnel.
3. Permanently mark the inside lid of the cooler with the sender's current
return address and telephone number in the event that the shipping label is
misplaced or ruined.
PACKAGING OF SAMPLES
1. Line all containers with two (one bag inside of the other) heavyweight
trash bags. Place samples and ice (if required) in the inside bag. Seal each
bag with a knot or by folding over the top of each bag and securing it with
filament tape.
2. Fasten caps securely. Bottles will not leak when the caps are properly
tightened. Do not use tape or parafilm on bottle caps. Tape may contaminate
the sample.
3. If multiple sample sets are included in a single container, label each set
of bottles and the ASR(s) with a letter or number to assist the NWQL in
grouping the samples together. One excellent approach is to place all the
bottles from a sample set in a mesh bag to keep them together.
4. Mark bottles sent to the NWQL with a permanent, waterproof marking pen or
with a preprinted label that will remain securely attached to the bottle. If
preprinted labels are used, take precautions to ensure that the label and the
information on it will remain intact and legible throughout the shipping
process.
5. All bottles must contain the following information:
station-i.d.
date of collection
time of collection
bottle type
field-i.d. (if applicable)
The information is critical because it serves as a link between the bottle and
the ASR. Without the information, bottle mix-ups and loss of data may occur.
DO NOT put analytical requests such as schedule number and labcode adds
or deletes on the bottle instead of on the ASR. Analytical work for a sample
is initiated by the ASR and supplementary information written on the bottles
may be lost.
6. Each shipping container should contain at least one ASR and all of the
bottles associated with that ASR. Do not send bottles in a container without
an ASR. Likewise, ASR's must not be sent without bottles. If a sample set
contains bottles that must be shipped in separate containers (for example,
chilled and unchilled), then each container must contain an ASR listing the
schedule to be used when analyzing the bottles in that container. The ASR's in
different containers may refer to the same site or station-i.d., but the
schedule and labcode information should apply only to bottles shipped with the
ASR.
7. Place ASR's in sealed, water-tight bags. When shipping samples in coolers,
the ASR packet should be taped to the inside lid of the cooler.
8. All of the bottles for a particular schedule MUST be sent in the same
container. If a schedule contains chilled and unchilled bottles, send the
entire sample with the chilled bottles. If schedules include bottles that
cannot be shipped together, notify the NWQL and the schedule will be corrected.
District personnel may also "delete" the labcodes for those bottles not
included in the container, and those bottles may be sent separately with ASR's
that request only the labcodes needed for those bottles.
9. Ship all glass bottles in foam sleeves, bubble packs, or in a foam box
designed for shipping. If glass bottles are sent in a carton, arrange the
bottles so that they do not touch each other (use cardboard inserts or foam
sleeves).
Do not rely on ice to provide cushioning for glass bottles.
10. FAM and RAM bottles may be sent with other inorganic samples, but wrap
them in bubble pack or foam sleeves and double-bag them in water-tight bags.
Sample bottles requesting chromium or nutrient analyses may be contaminated if
they contact FAM or RAM bottles.
11. Do not ship nutrient bottles with any samples that have been acidified.
Contamination from the acids used in sample preservation may create false
readings for some of the nutrient species.
12. Send samples for volatiles analysis in bubble-packs, sealable bags, or in
foam sleeves.
13. Do not use "blue-ice" or other types of commercially available refreezable
ices. These packets do not adequately keep bottles chilled, and they introduce
the possibility of contamination from an "uncontrolled" source.
14. Do not chill bottles with dry ice or with other substances that have a
freezing point below 0 degrees C; this may cause bottles to freeze and can
result in ruined samples or broken bottles.
15. Do not mix packing materials, such as styrofoam peanuts, with the ice.
16. Do not pack bottles in vermiculite. Vermiculite contains several
contaminants that may adversely affect the quality of data.
17. Include a shipping label with a return address for each container that is
to be returned to the district.
Labels should include the following information:
street address (no P.O. boxes)
account number and user code to bill shipping costs
18. Securely tape the outside of the container to prevent leaking and maintain
container integrity.
19. When feasible, Log-in will return mesh bags, foam sleeves, and other items
that are not ruined during shipping. Log-in will not return cardboard cartons
or other disposable shipping materials.
SHIPPING SAMPLES TO THE NWQL
None of the package-carrier services will deliver leaking coolers or boxes. To
ensure that samples are not discarded or set aside by the carrier, take special
precautions to ensure that the coolers or boxes are not leaking and, in the
case of coolers, that they can remain leak-proof even after the ice has begun
to melt.
Send time-dependent (chilled) samples to the NWQL by the most expedient means
possible. In general, ship all time-dependent samples by a reliable express
delivery service such as Federal Express, Government Overnight. Do not ship
radon samples in coolers. Ship radon samples using the "Fed-Ex Pak" for
government overnight. Never ship radon samples to arrive at the NWQL on a
Saturday. Federal Express is one shipping agent that provides reliable
overnight delivery of samples. Other agents may be currently (1994) available
or may become available in the future and should be considered.
Nontime-dependent (unchilled) samples may be sent the most economical way.
Both the U.S. Postal Service (USPS) first class mail and United Parcel Service
(UPS) offer 4- to 5-day delivery of samples using ground transportation.
By following the suggestions set forth in this memorandum, district personnel
will greatly reduce the possibility for error or delay in the analysis of their
samples. Additional questions about sample shipment and submittal may be
directed to the Support Services Unit Chief, Will Lanier (WDLANIER (303) 467-
8065), at the NWQL.
