Gray's Harbor Atmospheric Tracer Study, Gray's Harbor, Washington, 1992
When the performance of a dispersion model was deemed critical to estimating the health effects of a toxic waste source, T&B Systems performed atmospheric tracer tests to validate the model results. We sampled and analyzed ambient air for tracer material at fixed and mobile locations downwind of tracer release sites. This information, combined with meteorological data which we measured in the testing area, was used to determine pollutant dilution and validate the dispersion model calculations..
