‘Phytoremediation is the use of plants and their associated microbes for environmental clean-up’(Pilon-Smits, 2005). It is a natural, passive and efficient way of cleaning contaminated soil, water, and air. Every year, there are reports of contamination of swimmers due to the contaminated canal water round the Marineterrein in Amsterdam. The goal of this research paper is to investigate the different technics of water phytoremediation susceptible to be used to passively and actively purify the Amsterdam canal water and determine their applicability on and around a building. The founding of this research will be used to develop a new type of green façade that can remedy to the major problem of water pollution around the MarineTerrein in Amsterdam.
