Supporting Documentation for the TCEQ’s Ecological Benchmark Tables

This document discusses the sources and the derivations of the media-based, screening-level benchmarks. It provides supporting documentation for the surface water, sediment and soil benchmarks used as part of the ecological risk assessment (ERA) process. Conducting Ecological Risk Assessments at Remediation Sites in Texas (RG-263) is the parent document. Also see the separate Excel file containing the screening-level benchmarks, and other companion documents, available online at www.tceq.texas.gov/goto/era.
