Abstract : San Juan, Puerto Rico, a metropolitan area with a population of approximately one million people, is located on the northeastern coast of the island of Puerto Rico. The metropolitan area encompasses five municipalities, all of which are located within the San Juan Bay and Estuary (SJBE) system. The SBJE consists of five major water bodies (see Figure 1): Bahia de San Juan, Laguna del Condado, Laguna San Jose, Laguna la Torrecilla, and Laguna de Pijiones. The bay and lagoons are connected by narrow channels. Laguna San Jose (San Jose Lagoon), the most interior of the lagoons, is characterized by poor flushing. Much of the SBJE system has been significantly modified by dredging, sand mining, channelization, and sedimentation. In addition, anthropogenic influences from metropolitan areas of San Juan markedly impact water quality. Water quality problems of concern include high concentrations of coliform bacteria, low dissolved oxygen concentrations, eutrophication, and the presence of toxic substances.
