Review article: Phytoremediation Potential for Lead-Contaminated River Sediments, by Wendi Goldsmith, Senior Bioengineer.
"Recent developments in the application of wetlands for wastewater treatment and of phytoremediation for heavy metal uptake from upland soils suggest the feasibility of managed wetland plantings for uptake and removal of heavy metals from contaminated sediments. ... Engineered wetlands for removal of lead from riverine sediments appear to offer a theoretically sound approach provided that vegetation is regularly removed."
Poplar Treatment Systems
"Since 1989, CH2M HILL has pioneered the permitting, design, research, installation, management, and monitoring of poplar tree treatment and remediation projects. Demand for services related to this innovative technology has been high. In just 7 years, CH2M HILL has implemented 30 successful poplar tree projects, three of which were award winners. CH2M HILL has received positive recognition by regulators and major associations and has earned a reputation as the leader in the field."
"To be effective, phytoremediation projects must successfully integrate both the plant-based and engineering aspects of a system; this requires an interdisciplinary approach. CH2M HILL brings together the right team of agricultural and environmental engineers, plant and soil scientists (agronomy and soil physics, chemistry, management, and classification), hydrogeologists, and others with the skills to address each remediation project's specific problems. It is CH2M HILL's combined expertise and the ability to seamlessly integrate the technical disciplines that makes it unique among firms who use phytoremediation technologies."
Iowa City, Iowa.
"Current contracts call for removing lead and depleted uranium from firing ranges and industrial sites; extracting trace metals from water at a utility; and reclaiming tungsten from abandoned mines. With a partner, Edenspace is developing ways of reaching deeper into the earth with elecrokinetic techniques. Recently, the firm announced new commercial and retail applications for its patented hyperaccumulation technology."
Edenspace Systems acquired the phytoremediation business of
Inc. in mid-1999.

Occidental Petroleum Corp., Los Angeles, California
"Air Quality Solutions Naturaire® Systems harness the cleansing power of nature to remove common pollutants from indoor air. Naturaire® Systems, tested at the University of Guelph, remove up to 90 percent of common pollutants, significantly improving indoor air quality in an environmentally sustainable manner."
Assessment of Phytoremediation as an In-Situ Technique for Cleaning Oil-Contaminated Sites - A Report
"Phytoremediation, the use of plants and their associated microorganisms for the in situ treatment of contaminated soils, is a steadily emerging technology with potential for the effective and inexpensive cleanup of a broad range of organic and inorganic wastes. Based on a review of the relevant literature, we provide examples of the phytoremediation of petroleum hydrocarbons and discuss the key mechanisms as well as the special considerations involved in petrochemical phytoremediation. The benefits, limitations, and costs of phytoremediation compared to alternative approaches – including natural attenuation, engineering and bioremediation – also are discussed. Initial indications are that phytoremediation is effective at degrading and containing petroleum hydrocarbons in soil as well as transferring these compounds from soil to the atmosphere. The literature suggests that the degradation of petroleum hydrocarbons by microorganisms in the rhizosphere of plants is the primary loss mechanism for these compounds. Based on available information, it appears that phytoremediation of petroleum hydrocarbons is quicker but more expensive than natural attenuation and, conversely, slower but less expensive than most engineering techniques and traditional bioremediation methods. Preliminary screenings indicate that there are native and introduced plants that could be used in phytoremediation efforts in the Prairie and Boreal Plains Ecozones. Little published information exists, however, on the application of phytoremediation to oil-contaminated sites in Canada. Likewise, only a handful of studies examine in detail the specific mechanisms of petrochemical phytoremediation."
