Phytoremediation of organic contaminants, energetic materials and metals is mostly in the demonstration stage; there are no full-scale applications to date. Problems and needs are the slowness of the process—5 to 10 years—and what to do with the resultant biomass. Phytosensors can be used as indicators of phytoremediation progress, and coupled with GPS to guide management of crops, to monitor agro-security, and to detect explosives (e.g. buried landmines The Interstate Technology Regulations Council, is a group of about forty state regulatory bodies that banded together to share regulation information and eliminate repetition and duplication.
