Brownfield legislation and initiatives provide significant incentives for cleaning up and redeveloping commercial properties in prime locations that have been under-utilized due to environmental impacts of past industrial practices. One such brownfields site is at the Cambridge Research Park in Cambridge, Massachusetts. The property is the former location of a manufactured gas plant (MGP). MGPs heated coal and oil to produce gas used for lighting and heating. Byproducts from this process include coal tars and other organic compounds that behave as dense nonaqueous phase liquids (DNAPLs) and light non-aqueous phase liquids (LNAPLs) when in groundwater. Experts estimate that there are over 20,000 former MGPsites in the U.S.
