Role of phytoremediation for treatment of road runoffs through vegetaed filter strips
Abstract
Within the framework of the present feasibility study, the properties of the substrate DrainGarden® in combination with various plant consortia with regard to salt and heavy metal retention from road runoffsare to be tested. The substrate is characterized by high capability of storing and accumulating water and is able to release the moisture over a longer period of time to the surrounding soil organisms and plants. This circumstance offers the opportunity for additional purification of accumulated water volumes on site through suitable plant growth, thereby creating the framework conditions for ecosystem services such as water and air purification. The aim of this study is the on-site storing and accumulation of runoff water on high-traffic roads, their cleaning using plant-microbial processes and evaporation through the vegetation. Expectations exist with regard to reducing the environmental impact of runoff streams, reducing costs of existing water protection facilities, closing material cycles and contributing to a sustainable design of traffic problems.
