With the increasing environmental pollution, access to clean water has become an important issue all over the world. Therefore, it is quite important to obtain new water resources or to use existing resources more effectively. In this regard, the usability of groundwater for drinking and irrigation use was investigated in Karabuk province in Turkey. The locations of wells in Karabuk province were determined and the effects of industrial and agricultural pollution on groundwater were evaluated. Groundwaters were sampled at 22 different sampling points to determine the effects of industrial pollution on water quality. Samples were collected seasonally (wet and dry season) during the 12-month project from selected sampling points. Flow rate, temperature (T), pH, electrical conductivity (EC), total dissolved matter (TDS) and pH measurement were performed in situ for the determination of groundwater quality. Analyses of major ions (Ca, Mg, Na, K, CO₃, HCO₃, CI, SO₄), trace elements (B, Li, Sr, Fe, Mn, Cu, Pb, Zn, As, Se, Ag, Hg, Cr, Cd, Co.), nitrite (NO₂) and nitrate (NO₃) in water samples are carried out to investigate chemical properties. As a result of the analyses the following parameters were found to be elevated in groundwater during the wet season: pH (up to 9.62), sulphate (476 mg/l) and iron (0.28 mg/l). Elevated levels of the following parameters were also measured in the dry season: pH (up to 9.77), sulphate (up to 614 mg/L), nitrate (up to 50.50 mg/l) and iron (up to 0.439 mg/l). All other values of measured parameters were found to be below the upper limits in terms of drinking water. Evaluation of the study data showed that, only well (K5) was found to be in the “Usable-Doubtful” class for irrigation during the wet season.

土耳其卡拉布克省用于饮用水和灌溉目的的地下水质量评估

随着环境污染的加剧，获得清洁水已成为世界范围内的重要问题。因此，获得新的水资源或更有效地利用现有资源非常重要。在这方面，在土耳其的卡拉布克省调查了饮用水和灌溉用水的可用性。确定了卡拉布克省的水井位置，并评估了工农业污染对地下水的影响。在22个不同的采样点对地下水进行了采样，以确定工业污染对水质的影响。在为期12个月的项目中，从选定的采样点按季节（湿季和干季）收集样本。流量，温度（T），pH，电导率（EC），现场进行总溶解物（TDS）和pH测量，以确定地下水质量。分析主要离子（Ca，Mg，Na，K，CO₃，HCO ₃，CI，SO ₄），微量元素（B，Li，Sr，Fe，Mn，Cu，Pb，Zn，As，Se，Ag，Hg，Cr，Cd，Co。），亚硝酸盐（NO ₂）和硝酸盐（NO ₃）在水中进行样品以研究化学性质。分析的结果表明，在雨季期间，地下水中的以下参数升高：pH（最高9.62），硫酸盐（476 mg / l）和铁（0.28 mg / l）。在干旱季节还测量了以下参数的升高水平：pH（最高9.77），硫酸盐（最高614 mg / L），硝酸盐（最高50.50 mg / l）和铁（最高0.439 mg / l） 。发现所有其他测量参数值均低于饮用水的上限。对研究数据的评估表明，在雨季，只有一口井（K5）被认为属于“可疑”灌溉等级。
