Navigating the TMDL Process: Sediment Toxicity

This report focuses on application of Toxicity Identification Evaluations (TIEs). The U.S. EPA and others have developed sediment TIE procedures which are conducted using both the aqueous matrix (sediment interstitial water) and the solid-phase matrix (whole sediment). While literature has demonstrated that efficacy of TIE procedures for identifying causes of toxicity in effluents and receiving waters, their application to sediments is less well developed. WERF initiated this project to evaluate the current state of the science for accomplishing TMDLs in waterways listed as impaired for sediment toxicity, including the ability to identify the sediment-associated pollutants in need of management to restore water quality. Published by WERF. 192 pages. Soft cover and online and PDF. (2007)
