Soilworks products are the industry’s top standard due to our insistence on creating high performance soil stabilization and dust control products that stand up to rigorous testing – both in the lab and in the field. Our commitment to quality and performance has led to our involvement and testing in hundreds of real-world situations. The following library of reports, presentations, specifications, approvals and other similar documents provide you, our customer, the transparency and dependable assurance that is expected from Soilworks.
The use of dust suppressants not only enhances dust control but can also significantly reduce the amount of water needed to effectively control dust. However, application of dust suppressants could also negatively impact the quality of underground water and surface water bodies through in- filtration or storm water runoff.

The purpose of this research was to identify dust suppressant products with minimal to no adverse impacts on water quality and aquatic life relative to use of water alone. Simulated stormwater runoff from small-scale soil plots treated with six dust suppressant products was evaluated for water quality and aquatic toxicity. The study also evaluated the quality of water leached through soils treated with dust suppressant products. The study de- sign replicated, to the extent possible, conditions under which dust suppressants are typically applied at construction sites in desert climates.

Dust suppressant products tested included:
• Chem-Loc 101 (surfactant)
• Enviro RoadMoisture 2.5 (surfactant)
• Durasoil (synthetic fluid)
• Jet-Dry (surfactant)
• Haul Road Dust Control (surfactant)
• EnviroKleen (synthetic polymer)
Overall, water quality results for the dust suppressant products were favorable and generally minimal, showing concentrations similar to water-only control tests on untreated soils for the majority of parameters evaluated. However, this study is not a substitute for site-specific monitoring of dust suppressant impacts and results should not be applied to products that were not tested.
