Environmental Monitoring

Environmental monitoring utilizes several measurement tools to determine the current state, or to establish patterns of change, of an environment. Such monitoring is the basis of environmental impact studies which determine the potential effects of development and other activities upon the environment. Environmental monitoring can include air quality monitoring, soil monitoring, and water quality monitoring.
