| Abstract: | This paper describes the results of a groundwater quality assessment conducted in two pilot areas, Balatina and Carpineni,
in the Republic of Moldova. Shallow groundwater is the main source of drinking water in rural areas, but reliable data on
its quality are currently insufficient for developing rural water-supply systems with standard designs. The main components
of the study included a field sampling program (including pesticides), an evaluation of the reliability of existing drinking-water
data, an analysis of land use and groundwater-pollution risks using GIS, and the formulation of recommendations to reduce
risks for public health.
Microbiological, nitrate, and selenium contamination are most serious in the villages. These contaminants should be given
priority in addressing drinking-water aspects for rural water-supply development in the two pilot areas. Pollution occurs
mainly due to poor sanitary conditions. In a few shallow wells, traces of selected pesticides were observed, but the effect
of these levels of pesticides on public health is still unclear.
Limited resources of shallow groundwater of good quality occur outside the villages. Additional pilot studies should be implemented
to prove the technical and institutional feasibility of developing and protecting these resources.
