James Rayner to Present on Gravel Bed Reactors at International Mine Water Association Congress Virtual Event

James Rayner, FGS (United Kingdom) will present "Gravel Bed Reactors: A Semi-Passive Treatment for Metals and Inorganics' at the 14th International Mine Water Association Congress Virtual Event at 2:20 p.m. BST (GMT+1) on July 14, 2021.

James' Geosyntec co-presenters are Silvia Mancini, Ph.D., Rachel James, and Evan Cox (Ontario, Canada)

James Rayner, Senior Hydrogeologist at Geosyntec, has more than 18 years of experience in the assessment, management and remediation of contaminated land in the United Kingdom, Europe, North and South America. He specializes in multi-phase flow and reactive transport conceptualization and numerical modeling for site characterization, risk assessment and remediation in porous and fractured media. James has contributed to several research and industry collaboration programs and has been involved in several corrective action projects with particular expertise in evaluating and planning Monitored Natural Attenuation (MNA) and assessing remediation technology feasibility.

Silvia Mancini is a Professional Geoscientist and Principal based in Ontario with more than 16 years of experience focused on innovative solutions in site characterization, water management and treatment for the mining and metals, manufacturing, oil and gas, and legal sectors.

Rachel James is a Project Professional based in Ontario with more than 10 years of experience in aqueous geochemistry in the mining industry, including conducting bench- and pilot-scale treatability testing and water quality and biogeochemical investigations in support of mine development decision making for a broad range of projects. She is well informed in relevant emerging trends and guidelines initiated by environmental regulatory authorities.

Evan Cox is a Senior Principal Remediation Scientist based in Ontario with more than 22 years of experience focused on managing and directing soil and groundwater remediation projects dealing with emerging and recalcitrant contaminants.

Members of the International Mine Water Association (IMWA) share a common interest in mine water and mine drainage issues, and come with different skills, backgrounds, specialized expertise, and disciplines that range from science (e.g. chemistry, hydrogeology, microbiology, geophysics) to engineering (mostly mining and civil). The Association has 518 members, including pragmatic consultants and mining company employees, academic researchers (faculty, graduate students, and undergraduates), and government scientists and regulators.
