Thomas R. Elliot, Ph.D, P.Geo, P.Ag
Agrologist, Hydrogeologist, and Geoscientist
Thomas first practiced environmental consulting through hydrogeomorphology and watershed restoration of agricultural lands in the Sonora Desert. Using a blend of USGS approved and traditional knowledge methods, Thomas contributed to restoration of nearly 40,000 acres within the Cochise Rio de Aqua Prieta watershed. Since this start in 2002, he has upgraded his capacity through practice and academic pursuit of environmental engineering, geoscience, hydrology and agrology. These skills were reinforced by practical application in natural resource industries and federal government experience which contributed to state-level regulatory frameworks. In 2007 Thomas started a focused investigation of contaminant transport in soil and limestone aquifers, which was funded by the Canadian national government and industrial partners. The deliverable of his investigation contributed to policy guidance on nutrient management and aquifer vulnerability assessments in Ontario. Thomas subsequently pursued a multidisciplinary approach to agriculture, hydrology and subsurface reservoir management when overseeing programs in Carbon Mitigation for Global Environmental Change under the auspices of Canadian and US government agencies as well as Canadian, US and International corporate entities.
Thomas has continued those pursuits at Madrone and further engaged with surface and subsurface hydrology, water licencing and well certification, organic matter recycling facility operational planning, leachate management for soil transfer facilities, agricultural land assessment and remediation, development and application of land use optimization models for private and First Nation interests, nutrient management, soil slope failure and erosion mitigation, terrain stability and geohazard assessment, as well as development permitting.
