The general water quality in domestic wells in Torsås municipality including spatial and temporal differences (English)
Abstract [en]

The purpose of this report was to investigate the general water quality from domestic wells within the municipality of Torsås. The purpose was also to investigate the spatial and temporal variation of the water quality, including comparisons with other regions in Sweden. The results are based on 771 samples from domestic wells. The results from this survey showed that 84 % of the water samples had deficient water quality and 25 % of the samples showed that the water should not be used as drinking water. This proportion was significantly higher than in a national survey, most probably related to the higher proportion of dug well in Torsås in comparison to other regions in Sweden. The water quality data from domestic wells did not show any significant long-term (2004-2015) change in Torsås. There were spatial differences of the water quality within the municipality. The water quality in the inland regions had in general a better water quality than drinking water along the coastal areas. Drinking water originating from domestic wells located closest to the land-use category coniferous forest had better water quality than drinking water originating from domestic wells located closest to the land-use category deciduous forest and cultivations field. The conclusion is that there is a high proportion of deficient water and that the water quality in Torsås is more deficient than other regions in Sweden. There is also a spatial variation in water quality within the municipality.
