Groundwater outflows are an important feature of water circulation in nature, which is why they are extremely important in the natural environment. The main purpose of the study was to identify groundwater outflows across the fringe zone of Lake Wieprznickie as well as their hydrochemical characterization. Studies were conducted four times per year in the period from November 2010 to October 2013 for three hydrologic years. Fieldwork has shown the presence of 9 groundwater outflows northwest of the studied lake. The elevation of the outflows ranged from 150 to 155 meters. The outflows were found to be hillslope outflows that yield water continuously throughout the study period. The total mean discharge for all 9 outflows was 0.73 dm³•s⁻¹, which can be regarded as weak and average. The obtained results indicate that groundwater outflows to the Lake Wieprznickie provide 4% of the lake's volume. Most outflows created clusters of two or three outflows that formed the spring. Physical conditions such as specific conductivity and water temperature were subject to significant seasonal changes, while large stabilization was observed at individual measuring points. Total mineral content ranged from 320 to 610 mg•dm⁻³. Calcium was the main cation identified in the study and bicarbonate was the main anion, which is characteristic of shallow groundwater.

地下水流出是自然界水循环的重要特征，这就是为什么它们在自然环境中极为重要。该研究的主要目的是确定横跨Wieprznickie湖边缘地区的地下水流出及其水化学特征。从2010年11月到2013年10月，每年进行4次研究，历时3年。野外调查表明，在所研究的湖泊西北部有9个地下水流出。流出的海拔范围为150至155米。发现流出物是山坡流出物，在整个研究期间不断产生水。所有9次流出的总平均流量为0.73 dm ³ •s ^-1，这可以算是平均水平。获得的结果表明，流入Wieprznickie湖的地下水占该湖总体积的4％。大多数流出形成了由两个或三个流出组成的簇，形成了弹簧。诸如电导率和水温之类的物理条件会发生明显的季节性变化，而在各个测量点上都观察到较大的稳定性。总矿物质含量为320至610mg•dm ^-3。钙是研究中确定的主要阳离子，碳酸氢根是主要阴离子，这是浅层地下水的特征。
