Leviathan Mine was a sulfur mine in the East Fork Carson River basin, which caused extensive destruction of habitat and wildlife through discharge of acidic runoff and ground water into the Leviathan Creek watershed and the East Fork Carson River. The mine is now a federal Superfund site. Several interim measures have been instituted by various parties to reduce discharge of acid to the watershed. Invertebrate samples for aquatic bioassessment have been collected since at least 1997. This monitoring reveals the stream community is slowly and progressively reestabling itself in apparant response to the interim remedial measures. This project seeks to determine whether the aquatic bioassessment results, changes in the sediment and water chemistry over time, and the institution of interim remedial measures are indeed linked. This portion of the project involves analysis of samples collected during the 2005 field season and preparation of a manuscript for publication.
