Coastal Region of Kangkung, Kendal Regency, Central Java Province is one of the areas that experiencing water in the dry season. Groundwater exploitation is one way solution to meet the water needs for people in the area, especially in the dry season. Therefore it is necessary to study potency of ground water in coastal area of Kangkung. The research was  conducted to determine the potential of ground water in the confined aquifer in the Coastal Region of Kangkung, Kendal District which is expected to be utilized as a source of water to meet the needs of local communities. The method used in this research is  descriptive analysis to describe the condition of aquifer, however some things are delivered quantitatively. The aquifer condition was obtained from the interpretation of geoelectricity (resistivity) data supported by geological and hydrogeological observation data and pumping test data as secondary data. Groundwater quality analysis and simple hydrochemical analysis is with Chlorida - Bicarbonat Ratio (CBR) method to know the possibility of sea water intrusion. The results showed that the aquifer in the coastal area of Kangkung has the potential of 29.13 lt / sec ground water discharge which can be utilized to meet the needs of clean water 18,800 people. Although it is adjacent to the sea, the groundwater in the study area does not undergo sea water intrusion. Groundwater quality in this location is qualified as raw drinking water according to SK Menkes No, 492/Menkes/Per/IV2010 tentang Persyaratan Kualitas Air Minum. Keywords: ground water, geoelectric, intrusion  Wilayah Pesisir Kangkung, Kabupaten Kendal Provinsi Jawa Tengah merupakan salah satu daerah yang pada musim kemarau mengalami kekeringan. Pemanfaatan air tanah merupakan salah satu cara untuk memenuhi kebutuhan air bagi masyarakat di daerah tersebut, terutama pada musim kemarau. Oleh karena itu perlu dilakukan kajian potensi air tanah di daerah Pesisir Kangkung tersebut. Penelitian ini bertujuan untuk mengetahui potensi air tanah pada akuifer dalam (tertekan) di Wilayah Pesisir Kangkung, Kabupaten Kendal yang diharapkan dapat dimanfaatkan sebagai sumber air bersih untuk memenuhi kebutuhan masyarakat setempat. Metode penelitian yang digunakan dalam penelitian ini adalah diskriptis analisis untuk menggambarkan kondisi akuifer, namun demikian beberapa hal disampaikan secara kuantitatif. Kondisi akuifer diperoleh dari hasil interpretasi data geolistrik resistiviti dengan didukung data hasil pengamatan geologi dan hidrogeologi serta data sekunder berupa hasil pumping test. Analisa kualitas air tanah dan analisis hidrokimia secara sederhana dengan metode Chlorida – Bicarbonat Ratio (CBR) dilakukan untuk mengetahui kemungkinan terjadinya intrui air laut. Hasil penelitian menujukan bahwa akuifer di daerah Pesisir Kangkung mempunyai potensi debit air tanah 29,13 lt/det yang dapat dimanfaatkan untuk memenuhi kebutuhan air bersih 18.800 orang. Meskipun berbatasan dengan laut, namun air tanah di daerah kajian tidak mengalami  terintrusi air laut. Kualitas air tanah di lokasi ini memenuhi syarat sebagai bahan baku air minum sesuai SK Menkes No, 492/Menkes/Per/IV2010 tentang Persyaratan Kualitas Air Minum. Kata Kunci : air tanah, geolistrik, intrusi

Abstract Groundwater quality alludes to the state of the water that is arranged under the Earth's surface. Groundwater can accumulate in breaks in subsurface rocks and the centre of soil particles. Since various blends can break down in water and others can be suspended in water, there is a potential for pollution with harmful mixes including significant particles like Electrical Conductivity (EC), Total Dissolved Solids (TDS), and many others i.e. Ca, Cl, F, Mg, NO3, SO4, and Total Hardness. This study examines Groundwater Quality in the study area of the South-West zone of Surat city, Gujarat. The South-West zone of Surat city is situated on the shoreline, causes the groundwater of the concerned area highly affected by seawater intrusion. The present study determines the Ground Water Quality Index (GWQI) from the year 2006 to 2015. It also predicts the approximate ground water quality for the next 10 years. The outcome of this study suggests the need of certain improvement in ground water quality by an appropriate method such as Managed Aquifer Recharging (MAR). It will be beneficial for the people mainly dependent on the ground water, particularly living near the coastal region.

This paper presents the results of a groundwater quality assessment carried out in the karst coastal region of the West Aurunci Mountains (Central Italy). 55 spring and 18 well water samples, collected from 2016 to 2018, were analysed to study the main processes controlling the hydrogeochemical evolution and groundwater quality properties. In the study area, groundwater samples are mostly characterized by a Ca-HCO3 facies, indicating that the groundwater hydrogeochemical evolution is mainly controlled by the carbonate mineral dissolution/precipitation. The cationic and anionic concentrations confirm that groundwater samples belong to the order of Ca2+>Mg2+>Na+>K+ and HCO3−>Cl−>SO42−, respectively. Well water samples show, over time, an increasing mineralization with respect to the spring water samples. In more detail, the enrichment of Ca2+, Na+, and Cl- in well water samples is mainly due to the dissolution of calcite, dolomite, and halite minerals and secondly to a probable ion exchange related to seawater intrusion. Seawater intrusion, probably affecting the chemical composition of well water samples, was studied using ionic ratios, graphical approaches, and specific indices, such as the BEX index. Results suggest that carbonate weathering, ion exchange, and seawater intrusion in this karst coastal region are the major factors controlling groundwater geochemistry. This study shows that groundwater quality assessment, based on hydrogeochemical investigation techniques, has been a useful tool to characterize and model carbonate aquifers in Central Italy, with the aim of achieving proper management and protection of these important water resources.
