Environmental

In Michigan, 'light non-aqueous phase liquids' (LNAPLs) from fuel spills float on the water table and are significant because:

AThey naturally biodegrade completely within one year
BThey can spread laterally in groundwater and continue to be a source of contamination long after the initial spill✓ Correct
CThey are not regulated under Michigan law
DThey only affect surface water, not groundwater

Explanation

LNAPLs (gasoline, diesel, fuel oil) float on the water table and can spread, dissolving components into groundwater and creating persistent contamination. They are a common contamination type in Michigan from leaking USTs and spills at gas stations and industrial sites.
