69. Fate & Transport Modelling A group of environmental consultants headquartered in Cambridge, Massachusetts, USA. Their services include the use of air dispersion modeling in support of health risk assessments. http://www.cambridgeenvironmental.com/services/transport.htm

Fate and Transport Modeling of Pollutant Releases Description Cambridge Environmental develops, evaluates, and implements mathematical models to estimate exposures to pollutants and associated risks. Such models are useful, for example, in estimating concentrations of chemicals in media for which direct measurements are limited or unavailable. We are also expert in finding and correcting flaws in physical models upon which regulatory agencies and others depend. Cambridge Environmental uses computational, statistical, and graphical tools to analyze data with efficiency and intelligence. We identify patterns and inconsistencies in complex sets of data, use fundamental chemical and physical principles to build robust models, and thereby solve the problems at hand. Sample Projects A recent project completed for a chemical manufacturer involved a lawsuit filed by a volunteer fireman who had responded to a chemical spill caused by a leaking tanker truck. The fireman claimed that exposure to fumes caused him permanent injury. Cambridge Environmental estimated the chemical concentrations likely to have resulted from the incident, and showed that these concentrations were insufficient to cause the alleged health effects. Based in part on the strength of our analysis, the manufacturer reached a favorable settlement with the plaintiff.

Air Dispersion Modeling Tools Stone Lions Environmental Corporation is currently developing software to aid in the evaluation of air dispersion modeling results. A software program that allows the user to quickly compare the results of two Industrial Source Complex (ISC) model runs is due to be released early in 1997. Given two different ISC concentration tables, this program quickly calculates the difference in concentration (or deposition) at each receptor and gives the user both a table of differences and a graphic display which can be superimposed on a basemap. This program will be a valuable tool for anyone who wishes to evaluate differences in modeling results due to changes in source parameters, emission rates, meteorology, etc. For more information please e-mail to mgruber@stonelions.com or call Mark Gruber at (310) 377-6677.

AIR DISPERSION MODELING ECCI engineers have developed procedures to help define enforceable permit limits to control off-site concentrations of criteria pollutants and hazardous air pollutants to allow successful air dispersion modeling demonstrations while retaining reasonable operational flexibility at the source facilities. ECCI engineers have experience with specialty models and protocols to address unique operations and the associated air emissions including using the United States Army Open Burn and Open Detonation Model at multiple facilities. ECCI engineers have combined actual ambient air monitoring results with conventional air dispersion models to demonstrate off-site compliance in complex situations. Example Projects: Atlantic Research Corporation - Arkansas and Virginia ECCI has completed complex air dispersion modeling projects with HAP emissions from multiple sources and risk assessment driven off-site limitations for emissions from open detonation of waste rocket propellants.
