Technical and strategic planning for groundwater remedies

M&A has experience developing optimal remediation strategies — pump-and-treat, soil-vapor extraction, and in situ chemical and biological — to address subsurface contamination at industrial and mine sites, including Superfund sites. We often team with engineering firms to remediate contaminants such as industrial solvents, fuel hydrocarbons, perchlorate, nitrate, metals, sulfate, arsenic, and chromium. A key component of this work is developing numerical models to evaluate and optimize remedial strategies, which helps clients manage the costs and risk associated with long-term remedies. M&A has effectively applied chemical and biological approaches to localized contaminant source areas to increase mass removal and decrease remediation time.
