Try these first

1. 1.

   What is a sampling objective?

   Hint

   Think about why we sample, not just where.

2. 2.

   Define concentration.

   Hint

   It’s often expressed as mass per volume.

3. 3.

   What is the primary purpose of sampling objectives?

   • To determine sample volume
   • To define the purpose of sampling
   • To identify contamination sources

   Hint

   Consider what drives the decision-making process in sampling.

4. 4.

   True or False: If a detection limit is reached, it confirms the absence of the substance.

   • True
   • False

   Hint

   Think about what it means to measure something below your instrument's capacity.

5. 5.

   Given a lake with suspected high TSS levels, how would you design a sampling plan to ensure accurate results?

   Hint

   Think about how environmental factors might influence your sampling strategy.

6. 6.

   If an instrument's detection limit is 0.5 mg/L and your sample has a concentration of 0.2 mg/L, what implications does this have for the reliability of your analysis?

   Hint

   Consider what you need to adjust in sampling to ensure accurate measurements.
