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.
This EPA-led study assessed the water quality and aquatic toxicity impacts of various dust suppressants, including Durasoil, under simulated field conditions. Durasoil, a synthetic fluid applied without water, was tested for its surface runoff behavior, leaching potential, and ecological safety. Results showed that while Durasoil runoff had elevated total suspended solids (TSS) compared to controls, it met EPA data quality objectives (DQOs) for pH, total dissolved solids (TDS), total organic carbon (TOC), dissolved oxygen, and nitrate levels. Acute toxicity tests using fish (fathead minnows), algae, and aquatic invertebrates (Daphnia magna) showed no chemical toxicity, although Durasoil did temporarily trap invertebrates on the water surface in one test scenario—an effect not replicated in follow-up trials.
For projects near water-sensitive zones, stormwater basins, or ecologically protected sites, Durasoil delivers highly effective dust control without VOCs or leaching of harmful compounds, making it suitable for use where water contamination is a concern. Contact Soilworks for environmental documentation and regulatory guidance to support dust suppression efforts in compliance-sensitive or aquatic-adjacent environments.
