His consulting experience includes assessment, risk evaluation, and remedial design for the municipal solid waste, aerospace, power, chemical and vinyl manufacturing, and fertilizer industries nationwide. For the fertilizer industry, Warren consults clients regarding the assessment and remediation of environmental issues arising from nitrogen, phosphorous, metals, and low-level radioactivity associated with the use of fertilizers.
Frequently, Warren provides site technical direction and cost evaluation for the aggressive remediation or passive treatment of elevated arsenic, iron, lead, chlorinated organic compounds, and other contaminants in soil or groundwater. He has served as a technical expert or project manager on multiple projects involving geochemical assessments, natural attenuation, in situ bioremediation or fixation, and risk assessment.
Early in his career, Warren worked with Geosyntec Principal scientist Duane Graves and Matt Eick at Virginia Polytechnic Institute and State University in Blacksburg, Virginia. The Graves-Eick-Brady team developed two sequential extraction procedures used to assess metal immobilization processes, procedures now widely used throughout the environmental consulting industry.
Continuing to advance the state of the practice, Warren serves as a team member developing protocols for natural attenuation sampling and screening for organic and inorganic contaminants for the U.S. Department of Energy and the American Society of Civil Engineers.
