Contaminants Investigation of Aransas Dredge Spoil Islands, Texas, 1998-1989
The primary goal of this study was to gain preliminary information on the potential threat that contaminants in confined disposal areas adjacent to Aransas National Wildlife Refuge (Aransas NWR) pose to birds that utilize these areas, including the endangered whooping crane (Gnus americana) that often feeds on the dredge spoil study sites. In addition to concerns over potential contaminants in the spoil materials and their effects on natural resources, this study was also prompted by documentation by the Corps of Engineers in 1986 of a sediment sample from within the study area with an unusually high level of mercury (over 2 ppm). This sample was taken from an area which had received fugitive dredge spoil sediments from a breach in the containment dike on Rattlesnake Island. This high mercury level prompted great concern because there was no obvious or expected source to which it could be attributed. This study was intended, in part, to follow up on this concern and determine if greater alarm over local mercury levels was warranted.
