Herwig Goldemund is a Principal Scientist based in Georgia with more than 20 years of academic and professional experience as an environmental scientist and project manager.
Herwing's experience includes laboratory and field-scale research, land application of industrial residues, nutrient and trace element (e.g., metals) transport in the vadose zone, and college-level teaching.
As a consultant, Herwig's assists clients with soil and groundwater geochemistry, site assessment and remediation under CERCLA, RCRA, and state-led regulatory programs with emphasis on issues related to contaminant fate and transport with a specialty in inorganics. He also excels in contaminant sequestration; bioavailability and uptake; and the use of passive remediation technologies such as phytotechnologies, constructed wetlands, and natural attenuation. Furthermore, he assists clients in the areas of geochemical fingerprinting of landfill leachate releases, including leaching of constituents of coal combustion residuals (CCR); metals attenuation in soils and groundwater; and beneficial reuse of industrial by-products such as wastewater treatment sludges and ashes. He also provides expertise in alternative treatment approaches for leachate and groundwater impacted by volatile and semi-volatile organic compounds, ammonia, salts, and metals.
Herwig's expertise at CCR landfills and ash ponds is directed at geochemical data analysis and report development for the environmental aspect of investigations to assess closure strategies for these units. Furthermore, he has been involved in the implementation of alternate source demonstrations (ASDs) to show that certain CCR constituents are present in groundwater due to natural conditions. He has also evaluated groundwater geochemistry surrounding several CCR units to develop remedial strategies for groundwater and surface seeps.
Herwig is a noted authority on the treatment of landfill leachate with constructed wetlands and phytoremediation and has also applied phytoremediation to the remediation of arsenic in soils at former wood treatment sites.
