WHY AIRPORTS CHOOSE DIVISION 31 GEO
WHY D31 GEO?
Airports face unique environmental risks shaped by their operations, history, and surrounding land uses. PFAS is only one part of the picture.
Airports also encounter:
- Pesticides and herbicides used for vegetation control
- Contaminants migrating from nearby industrial or agricultural properties
- Legacy chemicals from historical operations
- Stormwater-driven transport of off-site pollutants
Division 31 GEO is the only aviation-focused environmental firm built around:
- Civil engineers, environmental scientists, soil scientists, microbiologists, analytical chemists, and construction professionals
- PFAS-exclusive investigation, remediation, and soil management expertise
- Regional aviation project teams supporting airports nationwide
- Proprietary tools that quantify PFAS and co-contaminant risk
- A philosophy centered on treating, stabilizing, and managing soils on-site whenever feasible
Every airport type has a distinct contamination profile - and we tailor our services to match those risks.

READY TO EVALUATE PFAS, PESTICIDES, AND CO-CONTAMINANT RISKS AT YOUR AIRPORT?
Let’s talk about your airport type, your operational history, and your contamination profile.
THE AIRPORT INDUSTRIAL ECOSYSTEM
Understanding the Full Contamination Landscape Surrounding Airports
AIRPORTS OPERATE INSIDE COMPLEX INDUSTRIAL ECOSYSTEMS
Airports do not exist in isolation. They sit at the center of dense, multi-layered industrial ecosystems where contamination can originate from on-site activities, off-site migration, and regional land-use patterns.
Understanding this ecosystem is essential for accurately assessing PFAS, pesticides, herbicides, petroleum hydrocarbons, solvents, metals, and other hazardous chemicals that may impact airport soils, groundwater, and stormwater systems.
Division 31 GEO specializes in identifying, characterizing, and managing contamination from all of these sources - not just PFAS.
