摘要

The alluvial sediments in the Delčevo region are a two layer porous environment built of different granulometric and filtration characteristics. The lower layer is a coarse porous water-bearing environment present udas a gravel sandy series (K = 96 – 276 m/day) and finer-grained granulometric sands with clay interlayers the filtration coefficient being K = 1.73·10^-2 – 17.28 m/day, underlying a layer of rather weaker filtration characteristics made up of sandy clays (K = 2.16·10^–3 m/day), and dusty sands the filtration coefficient being K = 3.15·10^–2 m/day. The udlithological-hydrogeological characteristics of the cover sediments do not provide sufficient protection of ground waters against contamination of the Bregalnica alluvion in the Delčevo region and pertain to the waters endangered from contamination. ud
