The aim of the project was to analyse the infl uence of small-scale sewage treatment on the
groundwater quality in areas with scarcity of freshwater. The content of chloride, nitrate,
heterotrophic bacteria and coliforms was analysed in 42 wells at the island of Ramsö, eastern
Sweden. Statistical analyses were carried out as well as calculations of chloride vulnerability
and a groundwater balance calculation. The study showed that the groundwater quality
was affected by the type and location of the sewage systems in various natural conditions
and that it is possible to develop a model for nitrate contamination on drilled wells taking
several signifi cant natural and technical factors into consideration.
