The Northern California Regional Chapter of the Society of Environmental Toxicology and Chemistry (NorCal SETAC) is a regional, scientific non-profit organization established to provide a forum for individuals and institutions engaged in the study of environmental problems, management and regulation of natural resources, education, research and development, and manufacturing and distribution in Northern California.

NorCal SETAC was established as a non-profit organization in 1991, and is currently the largest and most active regional chapter within SETAC in North America, and continues to attract environmental scientists, managers and engineers from academia, government, industry and environmental interest groups as our reputation for scientific interchange and education grows.
