NATIONAL EXPERTISE IN PFAS & CONTAMINATED SOILS FOR EVERY AIRPORT TYPE
PROTECTING INFRASTRUCTURE. REDUCING RISK. DELIVERING CERTAINTY.
AVIATION INFRASTRUCTURE IS BUILT ON SOIL - AND THAT SOIL TELLS A STORY
Across the United States, more than 20,000 aviation facilities sit on land shaped by decades of fueling, firefighting, maintenance, deicing, industrial activity, and construction. For airport managers, owners, contractors, and environmental consultants, the challenge is clear:
Contaminated soils are everywhere - and PFAS has changed the rules.
D31 GEO provides turn-key, aviation-specific PFAS and contaminated‑soil solutions that reduce cost, eliminate surprises, and keep projects moving.
Our work spans commercial hubs, relievers, GA airports, heliports, seaplane bases, private strips, and military airfields nationwide.
Below, you’ll find airport‑type‑specific contamination profiles designed to help you understand the risks, the sources, and the value D31 GEO brings to each market.
COMMERCIAL SERVICE AIRPORTS
High-Risk. High-Complexity. High-Value for D31 GEO.
Commercial airports contain the highest density of historical contamination sources in the aviation system. Decades of firefighting, fueling, maintenance, and deicing create multiple overlapping soil impact zones that directly affect construction, permitting, and capital planning.
Primary Contaminant Sources
- ARFF training & legacy AFFF
- Hangar suppression systems
- Fuel farms & hydrant systems
- Deicing pads & glycol areas
- MRO solvents & maintenance waste
- Stormwater infiltration basins
- Former landfills & buried fill
Why Airports Choose D31 GEO
We deliver turnkey PFAS and co-contaminant soil solutions that reduce cost, schedule risk, and regulatory exposure.
RELIEVER AIRPORTS
High Activity. Limited Documentation. Hidden Risks.
Relievers support intense GA jet operations, business aviation, and maintenance - often without the environmental documentation found at commercial hubs.
Primary Contaminant Sources
- Jet‑A fueling & self-serve fuel
- Business jet hangars & MRO
- Legacy AFFF use
- Leaded avgas deposition
- Undocumented fill & burn pits
Why Airports Choose D31 GEO
We help relievers avoid construction surprises, manage PFAS soils, and maintain compliance during expansion.
PUBLIC-USE GENERAL AVIATION AIRPORTS
The Largest Airport Category - and the Least Characterized.
GA airports often have decades of undocumented environmental history, including fueling, maintenance, agricultural operations, and ad‑hoc fire training.
Primary Contaminant Sources
- Small fuel farms & USTs
- Piston aircraft solvents
- Lead deposition
- Ag chemical loading areas
- Foam testing & fire training
- Old dumps & fill areas
Why Airports Choose D31 GEO
We provide affordable, turn-key soil evaluation and PFAS management tailored to small‑airport budgets.
MILITARY AIRFIELDS AND JOINT-USE AIRPORTS
The Most Heavily Impacted Aviation Properties in the U.S.
Military airfields have systemic, well-documented contamination from AFFF, fuels, solvents, munitions, and landfilling.
Primary Contaminant Sources
- Fire training areas
- Crash sites & emergency response
- POL (petroleum, oil, lubricant) zones
- Munitions storage & handling
- Solvent-based maintenance
- Landfills & waste pits
Why Airports Choose D31 GEO
We align PFAS soil management with DoD cleanup programs, FAA construction, and local development.
HOSPITAL AND EMS HELIPORTS
Small Footprint. Concentrated Contamination. High Sensitivity.
Hospital and EMS heliports often have localized but intense contamination zones, especially where fueling, hydraulic fluids, or deicing occur.
Primary Contaminant Sources
- Mobile or fixed fueling
- Hydraulic fluid leaks
- Deicing chemicals
- Rooftop drainage
- Occasional foam discharges
Why Airports Choose D31 GEO
We help hospitals identify and manage impacted soils during helipad reconstruction and utility work.
CORPORATE AND INDUSTRIAL HELIPORTS
Aviation Contamination Meets Industrial Contamination.
These heliports are often co-located with industrial operations, creating overlapping contamination profiles.
Primary Contaminant Sources
- Fueling & maintenance
- Industrial solvents
- Fire suppression systems
- Waste handling areas
Why Airports Choose D31 GEO
We provide integrated soil characterization and PFAS management across aviation and industrial regulatory frameworks.
SEAPLANE BASES
Shoreline Complexity. Mixed Contaminant Profiles.
Seaplane bases often sit adjacent to industrial shorelines, military sites, or legacy fill, creating complex contamination patterns.
Primary Contaminant Sources
- Fueling & maintenance sheds
- Solvent use
- Metals & petroleum in shoreline fill
- PFAS from nearby aviation/military sites
Why Airports Choose D31 GEO
We deliver upland + shoreline soil strategies, including PFAS and sediment considerations.
PRIVATE-USE AIRPORTS WITH FUEL OR MATINENCE
Commercial-Level Risks Without Commercial-Level Documentation.
Private airports with real infrastructure often mirror small public GA airports - but with less documentation and fewer environmental controls.
Primary Contaminant Sources
- Fuel farms & USTs
- Hangar maintenance
- Ag operations
- Occasional foam use
Why Airports Choose D31 GEO
We provide rapid, cost-effective soil evaluation and PFAS solutions for private owners.
MINIMAL-INFRASTRUCTURE PRIVATE STRIPS
Lower Risk - But Not Zero.
These strips typically lack fueling, maintenance, or firefighting infrastructure, but small contamination zones can still exist.
Primary Contaminant Sources
- Minor fuel spills
- Lead deposition
Why Airports Choose D31 GEO
We offer light‑touch assessments that protect owners from unexpected costs during construction or sale.
D31 GEO - THE NATIONAL LEADER IN PFAS & CONTAMINATED SOIL SOLUTIONS FOR AVIATION
Every airport is unique - but the soil challenges beneath them follow predictable patterns.
D31 GEO helps airports, contractors, and environmental consultants anticipate risk, control cost, and maintain compliance across every phase of construction and development.
Whether you manage a major hub, a GA airport, a heliport, or a private strip, our team delivers clear answers, defensible strategies, and turn-key PFAS soil solutions that keep your projects moving.
