Assessment of quality of water wells in rural areas in Tirana City, Albania

Abstract

Supply of safe water remains a challenge for the city of Tirana. Despite the improvement of the distribution network and recent investments, in many rural areas near the city of Tirana, drinking water supply is still not provided by the Tirana water supply distribution network. The lack of tap water has led to alternative findings of residents of these areas. One of them is the construction of private wells. The water quality doesn’t monitor by Laboratory of quality of water or Sanitary Inspectorate of Tirana. The lack of water quality control can lead to an undesirable situation for well water users. Given this situation, we thought to control the quality of well water in these areas. In this study are presented the microbiological data for the quality of well water used by families who have migrated from different areas of Albania to live near the city of Tirana during the last 5 years. The depth of wells varies from 5-100 meter. Sampling was done from April to September 2018. The total of samples was 180 from five areas of Tirana. Number of wells analyzed is 30. The data of this study show that 100% of water wells are contaminated by the presence of Escherichia coli. In 30% of water, wells are observed the presence of Entreroccocus fecal. Based on the data of this study, the water wells not recommended consuming by these families. We suggest residents treat the water before using. The simple method is chlorinating of water after deposition in tank, to eliminate the microorganism because they can be caused human health effects.Supply of safe water remains a challenge for the city of Tirana.
