Many industrial facilities are facing challenges with difficult pollutants that are not readily manageable with conventional BMPs (best management practices). Hear case studies on evaluating and treating difficult pollutants including dissolved metals, high solids and PAHs.
Mr. Gray is a water resources EIT with experience in the academic and consulting sectors. He specializes in stormwater treatment treatability testing and design to achieve permit compliance; stormwater green infrastructure design, monitoring, modeling, and applied research; groundwater flow and pollutant fate and transport resulting from stormwater infiltration; and development of technical guidance. As a research faculty member at Oregon State University Mr. Gray developed innovative stormwater treatment devices and filter media using biochar to remove heavy metal and other pollutants from stormwater runoff. As part of this work, Mr. Gray helped to design and construct 20 modular stormwater treatment devices that have been effectively removing heavy metals from runoff since 2015. More recently, Mr. Gray has designed and executed stormwater treatability pilot tests to compare removal of PAHs, PCBs, and heavy metals from stormwater runoff using different treatment technologies.
