The Exposure Analysis Modeling System, first published in 1982 (EPA-600/3-82-
023), provides interactive computer software for formulating aquatic
ecosystem models and rapidly evaluating the fate, transport, and exposure
concentrations of synthetic organic chemicals - pesticides, industrial
materials, and leachates from disposal sites.

EXAMS contains an integrated
Database Management System (DBMS) specifically designed for storage and
management of project databases required by the software. User interaction
is provided by a full-featured Command Line Interface (CLI), context-
sensitive help menus, an on-line data dictionary and CLI users' guide, and
plotting capabilities for review of output data. EXAMS provides 20 output
tables that document the input data sets and provide integrated results
summaries for aid in ecological risk assessments.
EXAMS' core is a set of process modules that link fundamental chemical
properties to the limnological parameters that control the kinetics of fate
and transport in aquatic systems. The chemical properties are measurable by
conventional laboratory methods; most are required under various regulatory
authorities. EXAMS limnological data are composed of elements historically
of interest to aquatic scientists world-wide, so generation of suitable
environmental data sets can generally be accomplished with minimal project-
specific field investigations.
EXAMS provides facilities for long-term (steady-state) analysis of chronic
chemical discharges, initial-value approaches for study of short-term
chemical releases, and full kinetic simulations that allow for monthly
variation in mean climatological parameters and alteration of chemical
loadings on daily time scales. EXAMS has been written in generalized (N-
dimensional) form in its implementation of algorithms for representing
spatial detail and chemical degradation pathways. The complexity of the
environmental description and the number of chemicals is fully user-controlled.
