GeoPro Talks: Adopting Digital Tools for Sustainable Remediation

Contaminated sites present unique challenges that require tailored approaches to investigation and remediation. Conceptual site models are conventionally based on snapshots of site conditions, but understanding how contaminant distributions evolve in the subsurface can provide deeper insights. Digital tools based on fundamental physical transport and biodegradation reactions can enhance these models and support decision-making. This […]
GeoPro Talks: Incorporating In Vitro Bioaccessibility for Arsenic and Lead in Soil in Human Health Risk Assessment

The United States Environmental Protection Agency (USEPA) defines bioavailability as the fraction of an ingested dose that crosses the gastrointestinal epithelium and becomes available for distribution to internal target tissues and organs. Bioavailability data can be used to provide realistic information on potential health effects of contamination and modify site-specific soil clean-up levels. Bioavailability is […]
