This site was heavily contaminated due to the burning and disposal of warfare and industrial chemicals since 1940 through the 1970s.
Phytoremediation and root zone cleaning system.
Using green plants to clean up contaminated soil groundwater and wastewater.
However phytoremediation suffers several limitations.
Gies that might more efficiently clean up these sites.
Phytoremediation is however limited to the root zone of.
The root zone waste water treatment system takes into account the natural slope of the ground so that water flows from one device to another without any external energy input such as motor pump.
Once the reed plants create an established stand usually after the first growing season the reed bed requires little or no maintenance.
This introduction is intended to provide a tool for site regulators owners neighbors and man agers to evaluate the applicability of phytoremediation to a site.
This document defines terms and provides a framework to understand phytoremediation applications.
Phytoremediation is a bioremediation process that employs varieties of plants to eliminate transfer maintain extract or degrade contaminants in the soil and groundwater.
The contaminating material should always be present within the root zone of the plants to make it accessible to the roots.
Phytoremediation can be used to clean up organic contaminants from surface water ground water leachate and municipal and industrial wastewater.
And 3 the need to.
Also phytoremediation is a slow process and a contaminated site needs to be large enough to grow enough plants.
2 expiration is often not optimal because of less effective groundwater extraction through the tree root system.
Classification of phytoremediation on the basis of mechanisms.
The plants used in phytoremediation are generally selected on the basis of their growth rate and biomass their ability to tolerate and accumulate contaminants the depth of their root zone and their potential to transpire groundwater.
1 contaminated groundwater usually exceeds the 25 feet ft 7 6 meters m below ground surface bgs threshold for effective vertical tree root growth.
Plants also produce enzymes such as dehalogenase and oxygenase which help catalyze degradation.
As a cleanup system at a site with zinc contamination in the root zone of some of the trees.
Phytoremediation of contaminated sites should ideally not exceed one decade to reach acceptable levels of contaminants in the environment.
It is a compilation of.
