CONSIDERATIONS REGARDING WATER SUPPLY IN DOLHASCA TOWN, SUCEAVA COUNTY

Geomorphologically, Dolhasca town is located in the east-southeastern part of Suceava county, in the contact area of Suceava Plateau with terraces from the right part of Siret river at the confluence of the Siret and Somuzul Mare rivers. Geologically, the studied area is located on the Moldavian Platform and is characterized by the presence of Sarmatian and Quaternary deposits. Hydrogeologically, on the basis of data provided by wells located in this area, two types of aquifers: shallow and confined were separated. Shallow aquifer has been intercepted in the meadows of the Siret and Somuzul Mare rivers and consists of one or two porous-permeable layers, in the range of approximately 3-16 m depth. This aquifer has been identified in four wells belonging to the National Hydrogeological Network. Confined aquifer is accumulated in the Lower Sarmatian (Volhynian) deposits, in a depth range of about 20-250 m. Drinkable water sources that supply the Dolhasca town are made from two production wells: Poiana production wells constituted by six wells and Budeni production wells constituded by two wells. For delimitation of the sanitary protection areas for Budeni and Poiana production wells, the Wyssling analytical method was used. The hydrogeological protection perimeter boundary of two production wells was drawn taking into account the geomorphological conditions, the hydrographic network but also the regeneration area of groundwater resources.
