Reasons for not sampling: If vessel officials object or do not want to cooperate in the sampling
event, report this to DEC and terminate the sample. Do not sample if conditions aboard the
vessel are not safe.
Field Records: Use field record form or if this is not available please take notes. Information must
include the vessel name, location with latitude and longitude, sample port used, discharge type
(blackwater, graywater, mixed), discharge status, and who assisted and/or observed the sample
collection. Comments must be included on the form such as why the sample was taken. In the field
notes record the chlorine measurements, pH, and temperature along with time sample was taken. Place
field notes in top lid compartment of cooler before having lab or DEC pick up sample. If possible take a
photograph of the sample port. Photographs should include identifying information- like time, place- for
example include filed notes in photograph.
Custody: Ocean Ranger to stay with the box until it is picked up and custody form is singed and
completed. If vessel officials object or do not want to cooperate in the sampling event, report this to
DEC and terminate the sampling process.
Procedures:
Pre-sample:
1) Get ice: Partially fill cooler with combination of ice and water to make ice water slurry. Leave
enough room for full sample bottles.
2) Inflate the two 1 liter collapsible bottles with air prior to adding liquids
3) Put on safety goggles and gloves.
4) Fill out initial information in field notes.
5) Flush port: to clear line of standing water have ten times the sample volume discharged into a
bucket or container prior to sampling.
Sample:
1) Have ship’s crew fill all and cap all provided bottles. Fecal bottle must not be rinsed,
filled only once, and not overflow. Use filled 125ml unpreserved bottle to perform test
below in the following order:
2) Chlorine test: Take one of the strips and place in 125 ml unpreserved sample bottle.
Move strip back and forth for 30 seconds. Remove and compare results to color chart on
the bottle, find the closest color match. The first pad from the end is total chlorine, the
second is free chlorine. Write results in filed notes and on chain of custody form.
3) Record temperature. Insert thermometer up to the insertion line on thermometer.
When temperature is stable (not changing) record temperature to nearest 0.5 degrees
Celsius.
4) pH test: Dip one pH test strip into 125ml unpreserved sample bottle. Read when there is
no further color change, and while still moist. Compare to color chart on container.
5) Tamper-resistant seal- use to seal cooler when all samples are placed inside.
6) Properly dispose of test strips and gloves.
Sample drop off information:
Contact DEC or Crowley contact to arrange a sample-pick up from the vessel. Provide vessel
location information.
