Questions and Answers

What is the specific gravity of water?

1 (correct)

0.5

If the specific gravity of a contaminant is less than one, what will happen to the substance in water?

It will sink in water

It will dissolve in water

It will remain at the same level

It will float on water (correct)

What is the main difference between Light Non-Aqueous Phase Liquid (LNAPL) and Dense Non-Aqueous Phase Liquid (DNAPL)?
