Preliminary Technical Program

The Technical Program is organized into keynotes, breakout sessions, a plenary session, and luncheon presentations. Each NEMC technical session consists of 4 – 8 oral presentations. The TNI sessions are primarily meetings of TNI committees and special sessions on laboratory quality, assessor issues, and updates on TNI activities.

All NEMC sessions and TNI meetings are open to all attendees according to your registration. Attendees have the ability to view presentations in-person or view a recorded version that will be made available shortly after the symposium. Registration is by full conference, which includes all events, or daily.

The Forum on Environmental Accreditation

The Forum on Environmental Accreditation (the Forum) held concurrently with NEMC, is the principal conference for addressing policy and technical issues affecting the accreditation of environmental laboratories in addition to field sampling and measurement organizations. The Forum features open public meetings of all TNI committees to allow quality professionals, chemists, analysts, microbiologists, engineers, and managers from federal and state agencies; commercial, municipal, state and federal laboratories; and many others who are actively involved and interested in laboratory accreditation issues to review what has been done and participate in the efforts to establish a national program for environmental laboratories and field sampling and measurement organizations. Details for the Forum meetings can be found at www.nelac-institute.org.
