The scientific focus of this webcast will be on in situ passive samples for environmental monitoring and risk assessment. Other subjects may include the use of passive samplers to carry out surveillance, operation, and investigative monitoring that are necessary to meet the needs of regulatory agencies. With the continued maturation of passive sampling tools, this webcast will also offer more 'hands-on' discussions to tackle specific practical applications of these tools. This webcast will be beneficial to scientists (experts to first-time users), policy makers (regulatory authorities, accreditation bodies) and end users (companies, laboratories, and municipalities) that have a need for monitoring environmental pollution. Participants in the panel discussion period on Day 3 (April 26) will include several speakers from the previous days who will continue discussions with the audience.

More information on the 7th Passive Sampling Workshop and Symposium is available through the U.S. Geological Survey web site.
