HAZWOPER 40: Lesson 15 Quiz
1. Written records of sample collection, transfer, storage, analysis, and de-
struction are necessary for two reasons: to help ensure the proper interpreta-
tion of analytical test results, and:: To provide supporting evidence in case of a
legal action
2. If the soil is not hard and rocky, an auger can be used to bore a hole to
a desired sampling depth. Which type of auger has limited use for sample
collection?: Post hole auger
3. To collect a shallow sample that is more than 10 feet from the water's edge,
which sampler can be used?: Pond sampler
4. Typically, environmental samples contain dilute concentrations of pollu-
tants and are not as hazardous as the:: Hazardous waste samples
5. It is important to realize that the water standing in a well, and immediate-
ly surrounding a well, does not generally represent the groundwater to be
sampled. Therefore, the well must be (blank) before sampling by pumping or
bailing it.:
6. When manually sampling from a drum, cover drum tops with plastic sheet-
ing or other suitable non-contaminated materials to avoid:: Excessive contact
with the drum tops
7. Once collected, soil samples should be kept at their in-ground temperature
or lower. Refrigeration to what temperature with a minimal holding time is also
required?: 4 C
8. A device that is commonly used for sampling is called a drum thief. Its glass
tubes are inexpensive and can be disposed of instead of decontaminated.
One drawback is that if the liquid has a low viscosity, it can be difficult to
maintain:: A vacuum in the tube
9. Peristaltic pumps are limited in the lifting capacity; however, they have an
advantage in that the same system can be used not only for purging but also
for:: Sample collection
10. In order to prevent cross contamination of samples, (blank) must be thor-
oughly decontaminated after each use.: Sampling equipment
