Home Who We Are What We Do Products Research Library Laboratory Evaluation of Fugitive Dust Suppressants Simpson Weather Associates (SWA) has been completing independent third-party laboratory evaluation of fugitive dust suppressants since the early 1990's for dust suppressant vendors, material handling facility, mines, material customers, and material transporters. The majority of this work has been completed on the evaluation of in-transit dust suppressants. Hundreds of both body and topical treatments have been evaluated. SWA's laboratory testing protocol evaluates the response of dust suppressants when exposed to simulated environmental stresses, such as drying, thermal, precipitation, and wind. The purpose of the laboratory evaluations are to identify dust suppressants that are likely to be successful during field use. Dust suppressants passing the controlled laboratory evaluation stresses can be recommended for evaluation. The laboratory evaluations also allow dust suppressant vendors to fine tune application and concentration rates prior to more costly and time consuming field evaluation. CONTACTS G. D.

Home Who We Are What We Do Products Research Library Simpson Weather Associates (SWA) was established in 1974 and incorporated in 1980. Originally founded to deal with fundamental and applied problems in meteorology, SWA's environmental consulting has expanded to include areas in airborne- and space-based Doppler wind Lidar applications, air quality modeling and monitoring, fugitive emissions control, and specialized field measurements, software integration, and instrumentation development. Core scientists are augmented by highly experienced and qualified affiliated associates who are called upon to deal with specific problems. A full-time technical and support staff is also expanded periodically by part-time staff drawn from the University of Virginia community. © Simpson Weather Associates 1980 - 2021 809 East Jefferson St. Charlottesville, VA 22902 Phone: (434) 979-3571 Fax: (434) 979-5599 Back to top
