This year, the Symposium’s theme is “Reliable Data for Sound Decision Making.” Some of the highlights for the Symposium are:

  • A special half-day general session focused on the conference theme;

  • A special session featuring updates from EPA program offices;

  • 134 oral and poster presentations in the NEMC portion of the Symposium on a variety of cutting-edge environmental monitoring issues;

  • Meetings of TNI Committees to further TNI efforts on environmental laboratory accreditation, proficiency testing, and accreditation of field sampling and measurement organizations;

  • A public meeting of the Environmental Monitoring Coalition;

  • An exhibit program showcasing the latest innovations in environmental monitoring;

  • An Innovative New Technology Showcase;

  • Five vendor lunch presentations;

  • Two keynote presentations; and

  • A full day session focused on laboratory accreditation issues in general, and California specifically.

All NEMC sessions and TNI meetings are open to all attendees according to your registration. Attendees have the ability participate in-person at the Symposium or view a recorded version that will be made available shortly after the presentation.

Tuesday, August 6, 2024; 3:30 – 5:00 pm PDT

For the eight year in a row up to twelve (12) organizations will showcase innovative new technologies – sensors, apps, personal monitoring devices, among others – and network with managers and senior staff from commercial laboratories; the regulated community; the Agency’s regulatory program offices, regional and headquarters compliance staff; state compliance officials; tribal nations; the international community; the exhibitor community; and others involved in or affected by the Agency’s policies and procedures.


Meet with instrument manufacturers, laboratory suppliers, LIMS providers, and other laboratory service providers. See the latest developments in measurement technology, proficiency testing, sample preparation, and laboratory automation at the Exhibit Hall from August 5-7.


Friday has been set aside to consider topics of general interest to the broader accredited laboratory community, but to California laboratories specifically, due to the new rule that became effective on January 1, 2024. This day has been organized into three major blocks of time focusing on:

  • Improving the Professionalism of the Laboratory Community

  • How to Be TNI (-2) Compliant

  • Determining What is Really Important in Laboratory Assessments
