This chapter presents a regulatory overview of on-site remediation, remedial investigations (RI), feasibility studies (FS), remedial technologies, and a simulated case study. The discussion of remedial investigations and feasibility studies also includes the development and selection of remedial technologies. The case study outlines a remedial investigation and feasibility study, as well as the selection of remedial technologies.

METLCAP A process for encapsulating hazardous heavy metal wastes in a proprietary type of cement. Developed and offered by Environmental Remediation Technology, Cleveland, OH. 

Recovery of spilled hydrocarbons has been occurring almost as long as petroleum has been refined. The earliest attempt reported was the use of pitcher pumps attached to shallow posthole depth wells along a breached pipeline. This pre-1900 effort was not driven by environmental concerns, but by its ease in recovery and the perceived economic value of the oil. Most recovery efforts were continued until the labor value exceeded the product value, and then stopped. Primitive equipment, coupled with a lack of understanding of the mechanics of product migration in the subsurface, and the relatively low value placed on the recovered product provided little incentive for the development of remedial technologies. 

Filtration is an efficient and inexpensive method for removing dust, particulates and bioaerosols from indoor air. High efficiency filters can remove up to 95 % of airborne particles as small as 0.3 microns. However, odor associated with gaseous VOCs cannot be removed by simple filtration and must be captured using adsorbents such as activated carbon and charcoal. Frequent replacement is needed since these adsorbents have finite capacity and cannot be regenerated. The aim of this project is to develop an effective remediation technology for common airborne VOCs found indoor. 

Pollution of soils and waters by human activities is an important and widespread problem. This pollution by, organic and inorganic substances can affect individual organisms, human populations, and ecosystems, each in its own unique way. In particular former military installations, often used for weapons production and nuclear power plants represent a ongoing and substantial threat to environment and human health because of the specific pollutants that can be released Solvents, explosives, fuels, radionuclides, heavy metals, and metalloids all have been identified in the environment around these installations. Remediation technologies for these contaminated sites have been developed based on conventional systems utilising physical and chemical treatments, such as excavation and incineration, pump-and-treat methods, ultraviolet oxidation, soil washing, etc. 

Some producers of triglyceride-based polyols have reported the development of odor-remediation technologies for their products, but these developments are proprietary and details are not available at this time.

Broach, and R. E. Dugan, Eds. in Proceedings of the SPIE 14th Annual International Symposium on Aerospace/Defense Sensing, Simulation and Controls, Detection and Remediation Technologies for Mines and Minelike Targets IV, April 5-9, 1999. 

The developer claims that the cost effectiveness of the technology with respect to initial, operating, and maintenance costs makes it a preferred water remediation technology. 

Soil vapor extraction is a commercially proven technology, and according to the vendor, the Vaportech enhanced volatilization method has been used in many full-scale remediations. The developer has performed held studies using hot air injection to further enhance the performance of this technology. The Vaportech technology is commercially available from Envirogen, Inc., formally MWR, Inc. 

According to the technology developer, the Trozone soil remediation system is a closed-loop, ex situ process that uses a mixture of technologies that include ozonolysis, reverse osmosis, and enzymes. 

The technology developer claims that the estimated cost for using the Trozone soil remediation system is 30 to 1000 per ton of waste treated (D102921, p. 23). 

According to the technology developer, the soil remediation system was used in full-scale cleanups at the following three sites with the indicated total project costs ... 

According to the technology developer, the total cost for using the in situ microbial filter technology is approximately half of the estimated pump-and-treat cost, while involving only about 10% of the usual volume of groundwater used in pump-and-treat remediation (D152103, p. 1). 

The TRUclean soil washing system is a patented, ex situ modular process that uses soil washing, size fractionation, and gravimetric separation techniques to remediate soils contaminated with radionuclides and heavy metals. The technology developer, Lockheed Martin Corporation, claims... 

The Micro-Flo has been tested by Environment Canada under the Development and Demonstration of Site Remediation Technologies (DESRT) Program. It is commercially available from see Environmental, of Newfoundland and Nova Scotia, Canada. 

Soil Technology, Inc., has developed remediation technologies based on electrolytically produced water, which is its term for water that has been electrolytically processed to adjust its pH and reduction and oxidation potential. All information is from the vendor and has not been independently verified. 

Terrapure Systems, L.L.C. (Terrapure), is currently developing palladized iron remediation technology (PIRT). The deposition of small amounts of palladium (approximately 0.05 wt%) on the surface of iron particles may result in a bimetallic surface that can cause the dechlorination of aqueous organic compounds. The developers claim that the technology can be used as an in situ or ex situ process and can be applied to aqueous contaminants and soil. PIRT has been evaluated in bench-scale tests and is not currently commercially available. 

According to the technology developer, the AVR system can only be used on sludge that contains cyanide. Viking Industries no longer offers remediation technologies, and this technology is not commercially available.
