This research is based on information about approximately a hundred dug wells in five different areas in Finland. The fallout of sulphur compounds has determined the choice of the areas and the goal is to find out the degree of acidification of ground waters. The current situation has been compared to that 30 years ago as there was an investigation concerning the same wells at that time. The pH-value and degree of alkalinity of well water have systematically diminished in all the areas - most of all in areas of major sulphur compounds fallout. The observations and areas being few in number, no decisive conclusions should be drawn concerning the whole country.
