DEVELOPMENT OF SITE-SPECIFIC METAL TRANSLATORS IS THIS A CORRECT APPROACH FOR TERTIARY EFFLUENT?
Abstract:Site-specific study of translators for copper, lead, and zinc was conducted at the City of Lincoln wastewater treatment and reclamation facility. The City developed an approach for conducting the translator study by integrating the available guidance from the 1993 EPA Guidelines, 1996 EPA Guidelines, and the California State Implementation Plan. The translator is the fraction of the total recoverable metal that is dissolved in the downstream water. The translators are used to calculate a total recoverable permit limit from a dissolved water quality criterion specified in the California Toxic Rule (CTR). Based on the results of the study, the use of the site-specific translators is likely to result in significant relaxation of the total metal permit limits for pond effluent. However, site-specific translators for tertiary effluent are similar to the CTR default values with an exception of lead.
