This document presents the results of an updated survey of State and Federal drinking water standards and guidelines that was conducted by the Federal/ State Toxicology and Risk Analysis Committee (FSTRAC). FSTRAC consists of participants from State programs, United States Environmental Protection Agency (USEPA) Regional Office water management branches and USEPA Headquarters Office of Water who meet regularly for the purpose of exchanging ideas and information on the toxicology and risk assessment of water-related contaminants. FSTRAC provides an effective medium to coordinate Federal, State and local efforts in standards, guidelines and risk assessment methodology development. FSTRAC participation is generally open to State or Federal employees having an interest in the risk assessment of water contaminants.
