| Abstract: | Phytoremediation has received attention recently, due to promising field test results that indicate potential cost savings when compared with conventional treatments. The various plant-based technologies that comprise the category phytoremediation have some similarities, many differences, and different possible applications. Each application will be site specific and must be evaluated on a case-by-case basis by a regulator. A treatment remedy must be “protective of human health and the environment, maintain protection over time, and minimize untreated waste” (40 CFR 300.430). The regulator's view of phytoremediation is the same as for any proposed remediation technology and asks the basic questions, “Why do you think this technology will decrease risk to human health and the environment, and how will you show that it works?” This article reviews issues related to acceptance of the technology and discusses some of the regulations that may be applicable to phytoremediation. |
