Considering their relative density and solubility in water, how would hazardous substances behave that accidentally entered a groundwater system?
A) Sulphuric and nitric acids would sink to the bottom of the aquifer; kerosene would accumulate as a layer just below the water table.
B) Gasoline and kerosene would float on the water table; ethyl alcohol would dissolve and disperse in the groundwater.
C) E- coli bacteria may build up in groundwater but can be diluted or rinsed away with sufficient input of natural surface waters such as farm runoff.
D) Gasoline and kerosene would float on the water table, but most pesticides break down chemically when they reach the water table.
