In this study, hydrochemical properties of groundwater in delta of Kızılırmak River, which is the third longest river of Turkey and is located in the north-central part of the country were identified. For this purpose, physical properties pH, EC, TDS of samples taken from 48 wells in each period in June and October 2017 were determined, and major anion cation analyzes were performed. The hydrogeochemical properties of the waters were investigated by evaluating the data obtained and the effects of seawater intrusion in groundwater in the region were revealed. According to the analyzes results, the aquifer are not suitable for drinking and domestic purposes since EC values are higher than 2500 μS / cm for each period and Na, SO4 and Cl are above the limit values according to the Turkish Drinking Water Standard. Groundwater in the Kızılırmak Delta area were evaluated by using the Stuyfzand Classification System and the effects of the sea water intrusion were revealed. According to this; while the chemical character of groundwater in the Kızılırmak delta area is of changes NaCl towards the eastern part of the delta. In addition, there is a transitional zone between fresh groundwater and seawater. NaCl water type indicates the presence of seawater intrusion in the delta area and based on hydrogeochemistry 46% of the groundwater in the study are under the influence of seawater. To prevent salinization of the groundwater in area and detorioration of their quality, pumping must be stopped, and new wells must not be drilled in the area. [ABSTRACT FROM AUTHOR]

The need for drinking, use, energy and water for many purposes is increasing day by day as a source of life for all living things. Unplanned use of water resources is one of the most important problems today. Due to overuse, water resources are adversely affected and polluted by environmental factors. The management of water resources in this framework is important not only in terms of water quantity but also in terms of its quality. In this study, hydrochemical properties of water samples taken from 17 different points in Trabzon city Söğütlü River and its branches were determined and the basin was classified in terms of different water quality parameters by using spatial analysis techniques. Dissolved oxygen (DO) values at Söğütlü Stream ranged from 2.76 to 11.24 mg/l; Hardness values (FS) vary between 50.75-218.48 mg/l. pH value in surface water is between 6.63 and 7.5; the electrical conductivity (EC) value is between 61-258 µS/cm and the total dissolved solids (TDS) is between 58-223 mg/l. Surface water of Söğütlü Stream classified as Fe, Mn and Al is in II., III. and IV category according to "Classifications of Inland Surface Water Resources". In terms of NO2 and NO3 pollution parameters, also water class is in II., III. and IV. category. Physical, chemical and pollution analyses made on the surface water of Söğütlü River show that surface water has been polluted in recent years due to unfavorable environmental conditions.

The paper reports a study of the surface and ground water in Solaklı Basin, Trabzon, from an assessment of 33 sampling points. Many of the parameters analysed are only marginally acceptable as potable water, even though the samples were collected during the wet season. The highest concentrations of contaminants were found downstream of the centres of population. The results indicate regular monitoring is required and some measures should be taken to protect the limited resources. [ABSTRACT FROM AUTHOR]
