GROUNDWATER SOURCES IN THE CONTEXT OF RURAL DEVELOPMENT – CASE STUDIES

摘要

Groundwater sources used for drinking water in rural areas are affected by natural contamination (natural chemical compounds present in raw water source), or artificial pollution resulted from the use of fertilizers and pesticides (chemical contamination) and uncontrolled discharges of domestic waste (microbiological contamination). In this study it were analyzed three central water supply systems from Romania rural localities with raw water sources bacteriologically or chemically contaminated. Water quality analyses showed changes in water distributed to the population by identifying microbiological contamination or high levels of nitrates concentrations. This paper aims to discuss the groundwater sources for drinking water threatened by their location in rural areas of developing agro-zoo-technical domestic or industrial activities. Identification of hazards and contamination in critical points must be the basis of risk assessment in drinking water supplied for the population.
