Presenters: Fayaz Lakhwala, PhD (Evonik Industries AG) & Wahid S. Khan, PE, LSRP (Roux) 

Thursday, October 12 at 9am-12:15pm EST

This course will provide a background in the understanding of reaction chemistry and treatment options for metals in groundwater as well as allow environmental practitioners to better understand contaminant behavior and available treatment options to remediate groundwater contaminated with metals.

This 3-hour presentation will provide discussion on the following topics:

• Regulatory framework for heavy metal remediation
• Challenges for in situ remediation of heavy metals
• Removal mechanisms for major heavy metals
• Chemistry: Solubility and Stability of Heavy Metal Hydroxides and Heavy Metal Sulfides
• A detailed look at chromium, arsenic, and lead
• Treatability studies to select the right reagent for field application
• Design considerations for field applications
• Addressing commingled plumes
• Case studies and implementation
