2. Discussion on Contaminate Transport

Try these first

1. 1.

   What is contaminant transport?

   Hint

   Think about how substances move through the environment.

2. 2.

   What does the retardation factor represent?

   Hint

   R measures speed reduction.

3. 3.

   What is the retardation factor (R)?

   • Indicates contaminant concentration
   • Measures contaminant transport speed reduction
   • Defines the boundary conditions

   Hint

   It starts with 'R'!

4. 4.

   True or False: Core sampling is used to obtain only surface data.

   • True
   • False

   Hint

   Think about studying the layers!

5. 5.

   If a contaminant is found at a depth of 10cm in sediment with a concentration of 200 mg/kg and at 20cm with 150 mg/kg, calculate the average concentration between these two depths.

   Hint

   Sum the concentrations and divide by two.

6. 6.

   Given a retardation factor of 2 and a fluid flow speed of 1 cm/s, calculate the contaminant transport speed.

   Hint

   Remember the retardation factor reduces the speed of transport.
