Long Beach City Beaches and Los Angeles River Estuary Total Maximum Daily Loads for Indicator Bacteria

摘要

This technical report presents the required elements of the Total Maximum Daily Loads (TMDL) developed to address elevated concentrations of indicator bacteria at the Long Beach City Beaches (LBC beaches) and the Los Angeles River (LAR) Estuary and summarizes the technical analyses performed by the United States Environmental Protection Agency (USEPA), Region IX, to develop the TMDLs. Indicator bacteria represent a risk to public health and can impair recreational beneficial uses through beach closings. Health risks associated with indicator bacteria are discussed in more detail in Section 3.2. The goal of this TMDL is to determine the amount of indicator bacteria the LBC beaches and the LAR Estuary can receive and still meet water quality standards in the receiving waters.
