The ​TG230 provides a standard methodology for characterizing chemical exposure health risks at deployment locations in a manner that is consistent with military risk management doctrine.  Health-based, military exposure guidelines (MEGs) for chemicals are presented for air, water, and soil associated with various deployment exposure scenarios.

NOTE:  TG230 and the set of MEG values are undergoing a revision.  When available, updated materials will be posted here.  Information about the revision process is available from the Risk Assessment Capabilities Branch (usarmy.apg.medcom-aphc.list.racb@mail.mil).
