Objective:

The Center for Hazardous Substances in Urban Environments (CHSUE) completed its final year of existence under EPA’s Hazardous Substances Research Centers program with Collateral Grant funding (expiration date of August 31, 2007). The CHSUE was a cooperative activity between Johns Hopkins University (lead institution), University of Maryland, Morgan State University, University of Connecticut, and New Jersey Institute of Technology and covered EPA Regions 1, 2, and 3.

About 80 percent of the U.S. population live in metropolitan areas. These urban residents face a number of pressing environmental problems including exposure to toxic chemicals from contaminated sites, landfills, incinerators, abandoned industrial sites (Brownfields), industrial releases, lead, and pesticide use. In this context, EPA Regions 1, 2, and 3 have identified “Urban Livability” as a strategic priority. Focusing on the upper mid-Atlantic to the Northeast, the mission of the CHSUE was two-fold: (1) to promote a better understanding of physical, chemical, and biological processes for detecting, assessing, and managing risks associated with the use and disposal of hazardous substances in urban environments and (2) to disseminate the results of the research and provide technical expertise to various stakeholders including community groups, municipal officials, regulators, academia, and industry. A Research Program and an Outreach Program were funded through the Core Grant. The accomplishments of these two programs are described below.

Summary/Accomplishments (Outputs/Outcomes):

Through a combination of laboratory-and field-scale research, several projects within the CHSUE addressed contaminants and sources that are known to be prevalent in urban environments. These include gas and particulate emissions of mercury, other toxic metals, and organic compounds from contaminated sites and hazardous waste incinerators; chromium, arsenic, nickel, zinc, and cadmium in waters and soils; and chlorinated solvents in waste site gases, soils, sediments, and groundwaters. Risks to humans from toxic materials in urban environments come from contaminated groundwater and airborne particles and from direct or indirect exposure to contaminated soils. Several of the research projects within this Center were aimed at better quantifying the sources and cycling of toxicants and exposure pathways. These improvements in characterizing the sources and pathways will, in turn, help others to determine whether exposure levels have been or will be high enough to cause adverse health effects. The improved exposure assessment for our work can be used to determine priorities for risk management and for determining appropriate clean-up levels for contaminated sites. Some of the research projects that addressed exposure pathways also provided information that can be used to assess the effectiveness of natural attenuation as a means to reduce risks at contaminated sites.
