    The largest reservoir of freshwater in the world, representing more than 97% of all available fresh water reserves is groundwater. Much of the rural community in the Republic of Moldova (90%) use as source for drinking and household water - springs and wells.Springs as outflow of groundwater to the surface are the only natural water bodies. Theey are associated with many legends and customs, historical and cultural value representing the location. The water of springs is used to treat various diseases. Spring is a kind of indicator of environmental status of land. Shortcomings spring water consumption is that it can be consumed only water sources safely, systematically monitored the water quality. This paper includes information about water quality of springs in Orhei, Soldanesti Telenesti districts, where it is used for drinking needs. In research it was estimate the location in space and physicochemical characteristics of water springs, water pollution sources highlighted, set the type and qualification of water using.

    A spring is a component of the hydrosphere, where water flows on to the surface of the Earth from below the surface. This it is where the aquifer surface meets the ground surface. It may be the result of karsts topography where surface water has infiltrated the Earth’s surface, becoming part of the area groundwater. As sources of water supply in the Republic of Moldova underground waters constitute 15,2% (bore holes, springs and wells). The present work includes water quality investigations and aims to reveal local sources in river Nistru hydrographic basin (Rezina district) for drinking water provision in villages. Chemical composition of investigated spring’s water shows that in Rezina district 19% of springs are polluted with nitrogen compounds. Water of only 9% of springs is in conformity with the standard for drinking water. Water from 102 springs meets the requirements of irrigation that doesn’t present the risk of soil salinization (K > 18) – 1 383 L/min.

    THE WATER SPRINGS - SOURCES FOR WATER SUPPLY AND IRRIGATION IN THE NISTRU RIVER BASIN
    (2013) Sandu, Maria; Tărâță, Anatolie; Lozan, Raisa; Gladchi, Viorica; Duca, Gheorghe; Țurcan, Sergiu; Moșanu, Elena; Prepeliță, Afanasie
    The present study estimates chemical composition and status of the groundwater from the Nistru (Dniester) river basin (about 360 springs and fountains). Research includes defining of springs/fountains location, evaluating physicochemical features of water, highlighting of main pollutants and pollution sources, establishing of water type and quality. It was established that springs/fountains with water that meets the criteria for drinking scope constitute 21%, sanitary acceptable for consumption is water from 129 springs/fountains, with high content of dissolved salts (mineralization >1000 mg/dm3) and hardness exceeding 10 me/dm3 (very hard water) were in 18.5% of sources and approximately 25% of the springs are water polluted with nitrates and its content is more than the MAC from 1 to 6 times.
