I read a sentence below. 'Municipalities aerate drinking water that is drawn from underground aquifers in order to remove dissolved gases such as the foul-smelling H2S and organosulfur compounds, as well as volatile organic compounds, some of which have a detectable odor.' I wonder why a 'the' is inserted before the word 'foul-smelling'. Anyone have an idea?
