High-Priority Toxic Chemicals at NPL Sites CERCLIS (Comprehensive Environmental Response, Compensation and Liability Information System) database maintained by the United States Environmental Protection Agency (US EPA); EPA CLU-IN Contaminant Focus (; ATSDR Priority List of Hazardous Chemicals (; NIEHS SRP Contaminant-Specific Research ( 2011 At each NPL site, presence of 15 Toxic Chemicals selected from EPA, ATSDR, and NIEHS SRP priority chemical lists including: Aroclor, Arsenic, Benzene, Cadmium, Chromium VI, Coal Tars (DNAPL), Lead, Manganese, Mercury, Methyl Tert-Butyl Ether (MTBE), Perchlorate, Persistent Organic Pollutants (POPs), Polychlorinated Biphenols (PCBs), Polycyclic Aromatic Hydrocarbons (PAHs), and Trichloroethylene (TCE). From this list, those present at each SF site are listed in alphabetical order by chemical name, hazardous group (Base Neutral Acids, Dioxins/Dibenzofurans, Inorganics, Metals, Organics, Oxidizers, PAHs, PCBs, Persistant Organic Pollutants, Pesticides, Radioactive, and VOC), and media with SF site name, address, NPL status, and site ownership given.

HVRI Social Vulnerability to Environmental Hazards Index SoVI Hazards & Vulnerability Research Institute (HVRI): Social Vulnerability Index (SOVI(tm)) for the United States, (online database). Columbia, SC: University of South. Carolina: 2011. Permission given by Susan Cutter for inclusion in NPL Superfund Footprint Mapper. 2000 SoVI® 2000 by county is based on 32 variables. There are 9 significant components explaining 76% of the variance in the data. Among them are socioeconomic status, elderly and children, rural agriculture, housing density, black female-headed households, gender, service industry employment, unemployed Native Americans, and infrastructure employment. To visually compare the SoVI® scores at a national level, they are mapped using quantiles. Scores in the top 20% of the United States are more vulnerable counties (red) and scores in the bottom 20% of the United States indicate the least vulnerable counties (yellow). County No

IMR by race data: DHHS,Community Health Status Indicators Project Working Group, 2009. 2000 (US) 2007 (PR) 2005 (Hispanic, Black, White) IMR is the number of deaths of infants under one year old in a given year per 1000 live births in the same year by county. Map includes separate rates by race: Total, Hispanic, Black, and White. Groupings for each IMR variable based on quartiles.

Percentage of individuals aged 25 years and older who have not graduated from high school for each county. This is derived from dividing the number of individuals identified in the DHHS Community Health Status Indicator report by the sum of US Census county data on total population age 15-44, age 45-64 and age 65 plus.

USGS Landslide Incidence and Susceptibility United States Geological Survey (USGS) 2001 The map and digital data delineate areas in the conterminous United States where large numbers of landslides have occurred and areas which are susceptible to landsliding. Because the data are highly generalized, owing to the small scale and the scarcity of precise landslide information for much of the country, they are unsuitable for local planning or actual site selection. Rankings of the incidence/susceptibility include six levels from low to high. For explanation/determination of susceptibility see U.S. Geological Survey Professional Paper 1183: Landslide Overview Map of the Conterminous United States ( Area No
