This paper describes a pilot program funded by the U.S. Environmental Protection Agency (EPA) to verify, under predetermined criteria or protocols with adequate data quality assurance procedures, commercially-available systems for monitoring air, water, and soil. The objective of the pilot is to accelerate the acceptance of environmental monitoring systems in the marketplace through verification and reporting of technology performance. This paper identifies the stakeholder affiliations and lists the priority monitoring needs identified by the stakeholders. The benefits to vendors who have their technologies verified under the pilot are described, including EPA funding to support testing of the initial technolgoies verified under the pilot.
