56A RETROSPECTIVE-10 GROWING SEASONS USING POPULUS SPP. FOR POLLUTION CONTROL |
L.A. Licht, Ecolotree Inc., Suite 300, 505 E. Washington, Iowa City, IA 52240 |
Pollution control research using deep-rooted poplar began May 1988 with the University of Iowa's first riparian poplar buffer. The projects immediate purpose was reduction of fertilizer leakage to streams; the broader passion was to fundamentally change the engineered solution for cleaning up our polluted ecosystem using plants--starting with poplar.
The humble 16' x 400' tree strip planted by an unnamed stream near Amana, Iowa, was the subject of the doctoral thesis "Deep Rooted Poplar Tree Buffers Grown in the Ripanan Zone for Nonpoint Pollution Control and Biomass Production" ( 1990, Licht) and a patent pending titled "Method for Using Tree Crops as Pollutant Control" (1991, filed by Uof I). The EPA HSRC provided critical and necessary funding for proof of concept. Since then, over 60 projects designed by Ecolotree Inc., et al., are in the ground or on the drawing board around the U.S. and in Europe. This paper will be a retrospective of published and unpublished project results on costs, permitting, and treatment success for poplar-based phytoremediation. Key words: phytoremediation, poplar, permitting, Ecolotree, design
