Boosting Stormwater Infiltration & Treatment
WEBINAR: April 1, 2026, 10:00AM - 11:00AM PT
Join the Caltrans Division of Research, Innovation & System Information (DRISI) for this upcoming webinar as they share new guidance on how soil amendments like compost and biochar can improve stormwater infiltration, remove pollutants, and help meet the National Pollutant Discharge Elimination System (NPDES) permit requirements.
You will also hear how this work was developed in collaboration with Caltrans Design, Environmental, Maintenance, and Construction teams.
Learning Objectives:
- How soil amendments help water soak in naturally
- How improved soil can filter pollutants like heavy metals and microplastics
- Where these solutions can be used along highways
- What the new guidance means for Caltrans practitioners
Presenter:
- Dr. Sanjay Mohanty, Associate Professor, Department of Civil & Environmental Engineering, UCLA

What is NPDES?
The National Pollutant Discharge Elimination System permit program addresses water pollution by regulating point sources that discharge pollutants to waters of the United States.
Created in 1972 by the Clean Water Act, the NPDES permit program is authorized to state governments by EPA to perform many permitting, administrative, and enforcement aspects of the program.
