What We Do

The Ecosystem Processes Division (EPD):

• Uses state-of-the-art targeted and non-targeted analytical methods to generate data on the presence, concentration levels, and ecological effects of emerging priority chemical contaminants and their degradates in natural and built environments.
• Develops data and predictive tools to evaluate and prioritize chemical and nonchemical stressors based on the potential for human and ecological exposure, health impacts, and ecosystem degradation.
• Develops next generation cloud-based hydrology, water quality, and ecology modeling platform to facilitate data provisioning services, modeling workflows, mobile apps to support effective management of watersheds and ecosystems.
• Develops cost effective, reliable, and documentable means to identify, monitor, and control vapor intrusion into homes and buildings to reduce or prevent potential occupant exposures and associated health impacts.
