Toxicity of sediments surrounding the Gunpowder Neck Superfund Site at Aberdeen Proving Ground, Maryland. Final report, August 1992-December 1993
From the late 1940s through the 1960s, the standard practice for disposing of toxic chemicals at Aberdeen Proving Ground, MD, was open burning. This disposal site has since been placed on the National Priority List (NPt) by U.S. Environmental Protection Agency. In the spring 1992, sediment samples were taken from waterways that surround that disposal area. Chemical analysis and sediment toxicity assays (Ampelisca abdita) were conducted. Toxicity comparison, with sediment leachate from an Adapted Toxicity Characteristic teaching Procedure (ATCLP), were made using Daphnia magna and a fluorescent bacterium Photobacterium phosphoreum in MICROTOX assays. Amphipods showed a wide range of mortality in mud as well as coarser sediments indicating substrate preference is not critical to the outcome of the assay. Toxicity results from the leachates showed the sediments were not toxic to daphnia and MICROTOX assays.
