NEMC 2004 – 20th Annual National Environmental Monitoring ConferenceWelcomeWelcome to the 20th Annual National Environmental Monitoring Conference – NEMC2004. The conference is managed by the Independent Laboratories Institute (ILI) inassociation with the American Council of Independent Laboratories (ACIL) and InstantReference Sources, Inc. under a cooperative agreement with the U.S. EnvironmentalProtection Agency (U.S. EPA). The symposium series was established as a means offostering a partnership among the regulated community, its supporting laboratories andconsultants and state and federal regulators. Key to implementing these goals are thetechnical sessions, composed of both oral and poster presentations, the table topexposition and a varied offering of short courses.The conference has continued to grow and diversify in spite of difficult economic andgeopolitical times. This year again we have over 100 technical presentations in fourconcurrent oral presentation sessions, a poster session and a plenary session. This tieslast year's record for this venerable conference, long-known as the Waste Testing andQuality Assurance Symposium (WTQA). In this year’s program, you will find papers thatcover all aspects of environmental monitoring in all media (i.e., water, air, soil andwastes). Participants include experts from private industry, public agencies engaged inenvironmental monitoring (e.g., U.S. EPA, DOE, DoD and States) and academia.In addition to the long-standing sessions on organic methods and inorganic methods,we have added several new topics this year. For example, environmental monitoring asit relates to homeland security, laboratory accreditation, ensuring the integrity oflaboratory data, analysis of DOE mixed wastes, assessing the performance of newmethods and innovative approaches to environmental monitoring. Leveraging onpopular topics from last year we have sessions on advances in implementation of theTriad approach and measurement uncertainty and also advances in electronic datadeliverables. Finally, a round-table discussion on changing federal requirements tomanage environmental data will present the newest information on this subject.Complementing the technical sessions are plenary session presentations from leadersin government and industry, a large table-top exposition and three short courses.Join us in a relaxed atmosphere at the complimentary Opening Reception on Mondayevening. This reception is sponsored in part by the generous contributions of AnnualReviews, Dionex Corporation, Environmental Research Programs, EnvironmentalResources Associates, Environmental Standards, Inc. and Severn Trent Laboratories.Enjoy the conference, learn about changing technology, make new contacts, visit withold friends and let us know how we can help you.3
