This report summarizes the status of emerging sensor technologies for facilitating long-term ground water monitoring for a class of contaminants called volatile organic compounds (VOCs). It also describes a number of factors, including regulatory acceptance and cost-effectiveness, that influence the applicability of these technologies. The focus is on long-term ground water monitoring that is generally associated with a selected remedy, such as monitored natural attenuation or pump and treat.
