Abstract When a site-specific aquatic life criterion is derived for a metal, an adjustment procedure based on the toxicological determination of a water-effect ratio (WER) may be used to account for a difference between the toxicity of the metal in laboratory dilution water and its toxicity in the water at the site. The guidance contained herein replaces previous agency guidance concerning (1) the determination of WERs for use in the derivation of site-specific aquatic life criteria for metals and (2) the Recalculation Procedure. The guidance is designed to apply to metals, but the principles apply to most pollutants.
