    Concentrations of Polycyclic Aromatic Hydrocarbons in New Jersey Soils
    (Trenton, N.J. : Department of Environmental Protection, 2020-02) Sugihara, Teruo; Mueller, Robert; Boyer, John; Evenson, John; Froehlich, David; Giles, Gregory; Lester, Lori; Motter, Allan; Nuemann, Gregory; Schick, Kevin; New Jersey. Department of Environmental Protection
    The primary purpose of this study was to characterize the polycyclic aromatic hydrocarbon concentrations found in soils across New Jersey where the population density was 2,000 people per square mile or greater and in areas not known to be directly impacted by a discharge or historic fill. The large majority of the concentrations measured did not exceed the lowest levels of regulatory concern. Typically, surface concentrations exceeded subsurface concentrations at a given location. Although not the primary focus of the study, assessments of railroad track beds and asphalt surfaces as sources of polycyclic aromatic hydrocarbons were secondary purposes. Naphthalene concentrations decreased with increased distance from railroad track beds. Several polycyclic aromatic hydrocarbons decreased with increasing distance from asphalt surfaces.
