FDOH Final Cancer Review Study For Stephen Foster Neighborhood Released -June 2012
INDOOR DIOXIN DUST INVESTIGATION STUDY
The USEPA will implement an Indoor Dioxin Dust Investigation Study in selected neighborhoods in the City of Gainesville. On January 9, 2012, letters from USEPA were mailed out to preselected near site and background neighborhoods soliciting participation in the study and property access authorization from residential property owners. The Alachua County Environmental Protection Department is assisting USEPA in the mailout and receipt of letters from the contacted neighborhoods.
A workgroup of local health, environmental and technical experts will assist USEPA in identifying the homes to be tested from the group of homes whose owners have provided access authorization and completed survey questions. Sampling is tentatively scheduled for March/April 2012.
The Indoor Dioxin Dust Investigation Study is intended to investigate the issue of potential indoor dust contamination with dioxins in homes near the Cabot Koppers Superfund site and includes recommendations for sampling, testing and data interpretation. The study will include sampling of indoor dust from not more than 15 homes located near the Superfund site and from not more than 15 "background" homes located almost 2 miles from the site. The background homes are located in neighborhoods that have not shown evidence of soil dioxin dust contamination above State of Florida standards.
In July 2011, the Florida Department of Health (FDOH) submitted a
Indoor Dust Investigation/ Interpretation Workplan for the Stephen Foster Neighborhood to the USEPA. The workplan was developed by a Task Force composed of representatives from the FDOH, the Florida Department of Environmental Protection, Alachua County Environmental Protection Department, USEPA, the US Agency for Toxics and Disease Registry, the Alachua County Health Department and included representatives of Beazer East, the Alachua County Environmental Protection Advisory Committee and the Technical Advisor from the citizens group, Protect Gainesville Citizen's Inc. Both the City of Gainesville Commission and the Alachua County Board of County Commissioners have urged USEPA to implement the workplan.
