Hydrogeological characteristics of the alluvial sediments of the river Bregalnica at the Fortuna locality water supply, Stip

摘要

The total water capacity of the Fortuna wll system which uses the groundwater for the water supply for the town of Stip amounts to 171 l/s, but today this system yields only 50 l/s. The capacity of individual wells ranges frm 10 to 27 l/s with level variations ranging from 2,5 to 5.87 m. Water layers thickness is from 6 to 7 m. Mean filtration coefficient after test pumping is 0.4655 sm./s and after the granulometric sampling 0.2 sm./s. Mn content in the water is about 250 times higher than the maximum allowed.
