Competition Entry, 2009. Site contaminants, BTEX (benzene, toluene, ethylbenzene, and xylene), PAH (polycyclic aromatic hydrocarbons), and HM (heavy metals), were analyzed and classified according to their chemical properties and location on the site, and programs were linked to each category. They were further broken down based upon scale, flexibility of space, materiality, activity level, ability to mix with other programs, location in section, and density.
