THIS SAMPLE KIT INCLUDES TESTS FOR PFC’S (INCLUDING
PFOA & PFOS), SO ADDITIONAL PRECAUTIONS ARE
RECOMMENDED IN COLLECTING THESE SAMPLES TO LIMIT
POTENTIALLY CONTAMINATING SAMPLES DURING COLLECTION.
ADDITIONALLY THIS PACKAGE ALSO INCLUDES FIELDS
REAGENT BLANKS AND HOW TO BE HANDLED IN THE
SAMPLING PROCESS.
CLOTHING NOT TO BE WORN INCLUDES:
Tyvek suits, flame resistant clothing (including shoes, hats, bags,
gloves, headsets or accessories), Water resistant, stain resistant or
water repellant clothing including shoes, hats, bags, gloves headsets or
accessories. Rain gear made from fluoropolymers such as Gore—Tex™
or fabric with water resistant coating (breathable waterproof).
On the day of sampling it is recommended to wear clothing that has
been washed several times without fabric softener.
2 PVC. polyurethane, polyethylene or rubber rain gear can be worn.
AVOID USE OF THE FOLLOWING PERSONAL CARE
PRODUCTS PRIOR TO OR DURING SAMPLING:
Moisturizers and creams, fluoride containing toothpaste or
mouthwash, cosmetic products (including nail polish, dental floss,
shaving cream, shampoo and conditioner, sunscreen, insect repellent
and sanitizer.
DO NOT BRING THE FOLLOWING TO THE SAMPLING SITE:
Fast food (due to packaging), packaged food, pizza boxes and any
food such as baked goods or sandwiches wrapped in grease-proof
paper or bags, aluminum foil, plumber sealant tape (thread tape) and
plumbing paste, materials containing fluoropolymers such as PTFE
(Teflon), ETFE (Tefzel), PFA, FEP, waterproof paper or notebooks,
permanent markers (use ball point pens), plastic clipboards
FRB – FIELD REAGENT BLANK
A field reagent blank (FRB) is defined as an aliquot of reagent grade
water that is placed in a sample container in the laboratory and treated
as a sample in all respects, including shipment to the sampling site,
exposure to sampling site conditions, storage, preservation, and all
analytical procedures. The purpose of the FRB is to determine if
method analytes or other interferences are present in the field
environment. It differs from a trip blank in that it is “treated as a sample
in all respects, including shipment to the sampling site, exposure
to sampling site conditions, storage, preservation and all analytical
procedures.” The sample collector will expose the preserved laboratory
reagent water provided by the analytical laboratory to the sampling
environment by pouring the bottles of preserved laboratory
reagent water into the provided empty sample bottle. It is then capped
and labeled as the FRB collected at that sample location.
Procedure for preparation of field reagent blanks
FRB must be prepared at each sample location immediately before
collecting the sample. Individual bottles of preserved laboratory reagent
water for each location being sampled will be provided by the analyzing
laboratory. The sample collector will pour the water from one of the
bottles of preserved laboratory reagent water into the empty FRB bottle
designated for that sample location. The FRB label should identify that
FRB with that sample location.
PREPARATION
The laboratory reagent water and bottles must be stored where they
will not be exposed to contamination and maintained at a temperature
between 6°C and 15°C.
Planning for shipping of the collected samples
The following should be considered if the samples will need to be
shipped to the analytical laboratory:
• The hold time for the samples (which includes the FRBs) is
14 days from collection.
• The samples that are significantly above 10°C at the time of
collection will need to be iced or refrigerated for a period of
time in order to chill them prior to shipping or delivery to the
laboratory.
• Samples (which includes both the samples and the FRBS)
must be extracted by the laboratory within 14 days from
collection. Extracts must be analyzed within 28 days after
extraction.
• The samples must be maintained at a temperature no higher than 10°C during shipment within the first 48 hours from
sample collection.
• The samples will need to be received at the laboratory at
a temperature no higher than 10°C for the first 48 hours
after sample collection. After 48 hours the samples must be
received at 6°C or lower but must not be received frozen.
SAMPLE COLLECTION
1. Wash hands thoroughly before collecting samples.
2. Before putting on nitrile gloves, remove aerators or screens on sampling tap if present.
3. Before putting on nitrile gloves, let water run for about 3 to 5 minutes
and until water temperature has stabilized.
4. Put on a clean pair of powderless nitrile gloves.
5. Prepare the FRB for that Sample Location by pouring water from one
of the bottles of preserved laboratory reagent water into an empty
field reagent bottle, DO NOT USE any remaining laboratory reagent
water from that bottle for any other FRBS to be prepared. Discard
excess field reagent water at an appropriate location. Label the FRB
so that it is associated with that sample location.
6. Place the FRB in a sealable polyethylene bag specified for FRBs.
7. On the chain of custody, record the date and time that the FRB was
prepared for the sample location.
8. Collect the sample by filling one of the bottles containing the
preservative. Do not fill to overflowing since that will cause loss of
the preservative. A headspace free sample is not required with this
sampling. Be aware of where the bottle cap is placed while filling the
sample bottle.
9. Record the Sample location on the sample bottle label
10. Cap the bottle and invert 3 times to dissolve the preservative.
DO NOT OPEN.
11. Place the sample in a sealable polyethylene bag specified for
samples.
12. Record the date and time of the sample collection on the chain of
custody.
13. Place bottles in pre-cleaned cooler that has bags of PFAS—free
ice. Do not use blue ice. If you are unsure if the Ice contains
PFAS, double bag the sample bottle.
DOCUMENTATION & SHIPPING
1. Fill out the enclosed paperwork, making sure to include the date and
time you collected the sample, type of water, and sample ID. The
sample ID is to help you identify where the sample was collected.
Some common sample ID’s include: kitchen sink, outside tap,
treated sample, etc.
2. Enclosed paperwork with your sample.
3. Seal box to prepared for shipping sample to the lab. Samples require
overnight shipping and can be shipped using whatever shipping
service is most convenient for you. Samples should be shipped the
same day they are collected via overnight. Please ensure they arrive
at the laboratory Monday through Thursday.
4. Samples should be shipped to:
ResinTech Laboratory Services
Laboratory Receiving Department
1801 Federal Street
Camden, New Jersey 08105
PROCESSING
Typical turnaround is 5 business days from date of receipt. Some
samples may take longer if they are highly contaminated or if the
sample volume in the lab is significantly high.
Results will be emailed to the email address provided in the order and
on the paperwork.
ResinTech Lab Services reserved the right to reject any samples
that appear excessively dirty.
Please call for confirmation if there are
