In 1979, 1980, and 1981, the three Yves Biraud Seminars in Talloires, France, explored developments in the relatively new field of environmental epidemi ology. Since those early conclaves, the field has advanced considerably, yet the evolution of new technologies, specific to the purpose, have been slow (5, 25). Many of the research methods used for environmental epidemiology have been borrowed from infectious disease investigations or from occupa tional studies. This chapter describes the application of a specific public health monitoring technique, borrowed from occupational epidemiology-surveil lance for sentinel health events (53). Disease surveillance has been defined as a "state of continuing watchful ness" (60). The salient characteristic here is watchfulness, which is the objective of detecting a meaningful change of state, i.e. disease incidence. A surveillance system has been defined as the systematic collection, analysis, and dissemination of data. Many industries began to develop company-based surveillance systems in the 1970s as a response to the Occupational Safety and Health Administration (OSHA) legislation and the need for more data to study potential health effects from occupational exposures. 0163-7525/93/0510-0205$02. 00 ALDRICH & LEAVERTON A similar process is now occurring for environmental exposures with the implementation of federal legislation under "Superfund"
