Question:
Groundwater contamination spreads faster in which of the following formations?
Groundwater contamination spreads faster in which of the following formations?
Show Hint
Contaminant movement is fastest in
\[
\boxed{
\text{Fractured rocks}
\gt
\text{Sand and gravel}
\gt
\text{Clay}
}
\]
Updated On: Jul 23, 2026
- Clay aquifers
- Fractured rocks
- Shale formations
- Peat soils
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Fractured rocks contain interconnected cracks and joints that provide rapid pathways for groundwater flow.
As a result, contaminants move much faster through fractured rocks than through low-permeability formations like clay or shale.
Hence,
\[
\boxed{\text{Fractured rocks}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
