Sundsvall, Sweden, about 80.000 inhabitants. This city is located on the coast line on the Gulf of Bothnia, called the “High Coast” and declared “World Heritage Site” by the UNESCO. This long-term project is based on the contrast between the industrial activities along the bay of Sundsvall and the life style of a small Swedish town. Although the relative care for the wide and unspoilt environment by the Swedish government (the stem emitted by commercial activities is only vapour), the allocation of industries should be retought, according to an economic model based on a less dangerous impact on the ecosystem. The presence of industries along the bay of the cities may represent a risk, in terms of contamination of acquifers: sensibilising the public opinion of Sundsvall, and generally, the European governments about the probable water contamination in case of industry accident and focusing on the public health and the habitat preservation is the aim of this project. The risk is enourmous: some industries along Sundsvall bay, characterised by blast furnaces which work constantly, embody treats for the microhabitat, and for the quality of life of its inhabitants, in terms of increase of acquifer contamination probabilities in case of flood, and the consequent impoverishment of flora and fauna variety.
