Summary

The goal of this Remediation Guide is to assist field personnel in restoring impacted soil to a state consistent with the original land use. Sections I through IX of the guide are intended as a field reference for remediation of salt and/or hydrocarbon impacted soils. Documentation of basic soil science used to develop the field guide is included as appendices E (Soil Properties) and F (Soil Chemistry).

Summary

FoamFlex200 is a proposed innovative, patented oil absorbent technology for hydrocarbons and their derivatives. The product is an open-cell oleophilicpolyurethane foam with a hydrophobic effect greater than 95%. This allows the intact recovery of spilled hydrocarbons with less than 5% water. It can absorb about 30 times its own weight of any hydrocarbon.

Summary

Pyrolytic treatment offers the potential for the rapid remediation of 15 contaminated soils. However, soil fertility restoration can be highly variable, 16 underscoring the need to understand how treatment conditions affect soil 17 detoxification and the ability to support plant growth. We report here the first 18 pilot-scale study of pyrolytic remediation of crude-oil-contaminated soil using a 19 continuously fed rotary kiln reactor.

Summary

Pyrolysis of hydrocarbon-contaminated soils offers the potential for rapid remediation without destroying soil fertility. Here we elucidate the fundamental mechanisms of pyrolytic treatment and advance understanding of the surface properties of pyrolyzed soils. Using thermogravimetry and evolved gas analysis, we identified the two stages of pyrolytic remediation.

Summary

Pyrolysis of contaminated soils at 420 °C converted recalcitrant heavy hydrocarbons into “char” (a carbonaceous material similar to petroleum coke) and enhanced soil fertility. Pyrolytic treatment reduced total petroleum hydrocarbons (TPH) to below regulatory standards (typically <1% by weight) within 3 h using only 40−60% of the energy required for incineration at 600−1200 °C.

Summary

Thermal treatment technologies hold an important niche in the remediation of hydrocarboncontaminated soils and sediments due to their ability to quickly and reliably meet cleanup standards. However, sustained high temperature can be energy intensive and can damage soil properties. Despite the broad applicability and prevalence of thermal remediation, little work has been done to improve the environmental compatibility and sustainability of these technologies. We review several common thermal treatment technologies for hydrocarbon-contaminated soils, assess their potential environmental impacts, and propose frameworks for sustainable and low-impact deployment based on a holistic consideration of energy and water requirements, ecosystem ecology, and soil science.

Problem

An underground leaking motor oil storage tank went unnoticed and unidentified for 15 years. Two areas of soil were contaminated with motor oil.
