Petroleum hydrocarbons
Diesel and gasoline range organics, BTEX, hexane, methanol, and the wider VOC and SVOC set. Crude, condensate, lube and hydraulic oil, jet fuel, kerosene, bunker-C.
Pathway: accelerated biochemical treatment.
Soil & Water Remediation
Bring it to us, or we'll come to you.
Greenleaf remediates petroleum-impacted soil and water two ways: at our permitted facility near De Beque, or on your own site — using the same accelerated biochemical treatment either way.
Contaminants
Not just hydrocarbons.
Petroleum is the most common thing we're called for, but it is rarely the only thing in the ground. Greenleaf handles the rest of what shows up in a site investigation — and where a contaminant will not respond to biological treatment, we say so and use a different pathway.
Salts, chlorides & brine
Produced water releases, brine spills, and alkali or salt-impacted soils from habitat rehabilitation work. Chlorides, sulfates, phosphates, and nitrates in soil or water.
Pathway: excavation and disposal, or the Class I well for the liquid fraction.
Metals
Metals-impacted soils from industrial sites, sandblast media, scale, and legacy operations. Biology does not consume a metal, so nothing here is dressed up as treatment.
Pathway: characterization, then placement in a certified Section 3 cell.
Chemical spills
Self-neutralized acids and bases, glycols, methanol and ethanol, antifreeze, drum and vacuum truck rinseate, and the soil and absorbent that came into contact with them.
Pathway: depends on the chemistry — we will tell you which before you commit.
Impacted water
Monitoring and extraction well groundwater, pit and sump water, contact stormwater, dredge spoils and their wastewater, and process waters from industrial sites.
Pathway: Class I injection well or the lined pond system.
Low-concentration TENORM
Tank bottoms, filter socks, press cake, and residuals from cleaning pipelines, flow lines, and vessels — accepted below Colorado's administrative levels.
Pathway: characterization support, then certified disposal.
Most sites are a mixture
A tank farm release is hydrocarbon and metals. A produced water spill is salt and hydrocarbon. A legacy yard can be all three plus TENORM. Greenleaf handles the whole site rather than the one contaminant that suits a single process — which is the practical advantage of running a treatment capability, a Class I well, and certified cells at the same company.
The core capability
Accelerated biochemical treatment.
Two agents, applied together or alone depending on the season and the contaminant. The chemical releases hydrocarbon from the soil matrix; the biology consumes it.
Not conventional landfarming
Doses are typically applied once rather than repeatedly. Aeration is generally unnecessary. The process operates at high waste concentrations and is not oxygen-dependent. Where conventional landfarming runs for years, this completes in a treatment application plus a maturation period.
What it targets
- TPH-DRO and GRO — diesel and gasoline range organics
- BTEX — benzene, toluene, ethylbenzene, xylenes
- Hexane and methanol
- Other common VOCs and SVOCs in petroleum-impacted media
On the job
A crew working a client site.
Loader feeding the screening plant, dose applied on the way through, processed material stockpiled to mature. This is what the work looks like when we bring it to you rather than the other way around.
