The individual water intakes are an important source of water supply for human consumption in Polish rural areas. The wells are often not covered by research in range of water suitability for human consumption, therefore, a significant number of rural inhabitants use water of unknown parameters, physico-chemical and biological likely to contain contaminants harmful to humans.The main goal of this research has been determination of changes in concentrations of phosphorus compounds in water from wells located in the village Przeździedza. The research has covered the period from March 2009 until February 2010. The six wells constructed of concrete rings or from a stone has been analyzed. The following parameters has been determined: phosphate. The results of this research indicate that, poorly protected wells are characterized by worse water quality. The results confirm the fact that, poorly protected wells are characterized by a poorer quality of water. However, the average concentration of phosphate in all wells was very low, and each of them corresponded to the obligatory standards in Poland.
