The National Environmental Justice Advisory Council (NEJAC) is a federal advisory committee to the United States Environmental Protection Agency (EPA). This Report, therefore, focuses on those environmental justice issues raised by compromised aquatic ecosystems that EPA is empowered to address. That is to say, it examines, in the main, efforts that might be undertaken by EPA, as opposed to other agencies (whether federal, state, or tribal), and it focuses on sources of contamination and depletion within the United States, as opposed to global sources. This focus is not meant to suggest that NEJAC believes that the efforts of these other agencies and the contributions of these other sources are not important aspects of understanding and addressing compromised aquatic ecosystems; rather, it reflects NEJAC's role as a federal advisory committee to EPA.
