Public Health Assessment for Marion (Bragg) Dump, Marion, Grant County, Indiana,Region 5. CERCLIS No. IND980794366

摘要

The Marion (Bragg) Dump site area, in Marion, Indiana, has been classified as apublic health hazard to individuals who eat fish from the off-site pond. The pond water and sediment poses an indeterminate public health hazard because mercury was present at high levels in the initial sampling but was absent in a subsequent surface water sample. There is no apparent public health hazard from on-site exposure because access to the contaminated soil is restricted by a fence surrounding the site and by a clay cap that was installed over the dump. The presence of volatile organic compounds (VOCs); phthalates, such as di-n-butyl-phthalate and bis(2-ethylhexyl)phthalate; and arsenic in the groundwater could become a major concern. Future residents and constructionn workers could also be exposed to contaminants in subsurface soil that is uncovered during construction activities at the site.
