November 2012 will be the fifth time this dedicated biennial event will be held. WWEM has evolved into a very successful event since its inception back in June 2005. The event has firmly established itself as the number one event for Water/Wastewater and Environmental Monitoring professionals to attend. In 2010 a dedicated Gas Detection zone of companies who provide fixed and portable gas detectors and calibration gases was introduced those topics will be expanded to include hazardous areas for the 2012 event.
