“…Group D is Alkalineearth water with higher alkali content bicarbonate predominated, consisting of SB-1, SB-3, SB-9, SG-1, SG-2, SG-4, SG-6, SG-7, MA-1, MA-3, and MA-4. This group indicates the groundwater has flowed away from the recharge area [9]. The result supports the isotopic analysis, which shows that most groundwater in this group is affected by evaporation and oxygen shifting during flowing and infiltration.…”

“…Group A is alkaline-earth water bicarbonate predominated, consisting of SB-2, SB-4, SB-5, SB-7, SB-10, and MA-2. This condition indicates that groundwater comes from local recharge areas with a tendency dominated by clay minerals [9,16]. The isotope analysis also confirms this result that shows their relationship with the RMWL.…”

Raimanuk and its surroundings are a potential agricultural area in Indonesia. Sufficient groundwater in this area was a significant factor for supporting agricultural activities and household needs. Therefore, identifying the aquifer connectivity is essential to determine the groundwater utilization pattern in this area. This research aims to determine the aquifer connectivity based on stable isotopes and hydrochemical from the groundwater and the meteoric water (rainwater). The groundwater samples were taken from ten deep wells, six dug wells, and four springs. While the meteoric water samples were taken from four rainfed locations, samples were analyzed using Los Gatos Research DLT-100, Ion Chromatography Metrohm 830IC, and acid-base titration. The result shows there are four groups of groundwater. Group I is the springs that come from local meteoric water. Group II consists of the dug wells that evaporated and showed a relationship to the meteoric water that falls in higher elevations. Group III was the drilled well groundwater from the local flow system. Furthermore, Group IV is the drilled well groundwater with a more enriched δ18O isotope ratio due to water-rock interaction. Even though they are in a different group, there is a hydraulic connection between Group III and IV.

“…Sungai Varahi berada di dataran tinggi dengan elevasi +761 m dpl, dan juga menunjukkan bahwa memiliki kandungan alkali yang lebih tinggi (Ca 2+ dan Mg 2+ ), kandungan asam kuat yang lebih tinggi (Cldan SO4 2-) serta merupakan zona campuran, dimana pasangan kation dan anion seimbang. Hasil pengeplotan karakteristik kimia yang menyatakan bahwa kandungan alkali tanah melebihi kandungan alkali dapat disebabkan oleh batuan vulkanik dan batuan mineral lempung yang banyak mengandung Ca 2+ , Mg 2+ [11]. Selain itu, munculnya ion Ca 2+ di seluruh sampel air menunjukkan bahwa terdapat pertukaran ion antara air tanah dengan batuan breksi gunung api [5].…”

The objective of this study was to know the chemical characteristics of surface water in a segment of Sumpil River and the groundwater on its surrounding. The location of this study was in 3 cross sections, consisting of 1 well on the right of the Sumpil River, 1 well on the left of the Sumpil River flow, and 1 point on the Sumpil River flow. The chemical characteristics of the water were determined by the concentrations of cations and anions in the water sample using the Piper Trilinear Diagram with the GW Chart 1.30 computer program. Based on the results of the study, it was shown that the chemical characteristics of the Sumpil River water and the groundwater at the location of this study were the same, where all water samples had an alkaline earth metals content over the alkali content (zone 1), had a strong acidic content exceeding the weak acidic content (zone 4), have a balanced cation and anion pairs, none of which exceed 50% (zone 9), and shown that all of the water in the location of this study were fresh water.

Groundwater plays important role as the main water resource for human needs. The vulnerability of groundwater to contaminants both naturally and by human activities can be not avoided as a trigger for groundwater quality degradation. Hydrogeochemical become important highlights in groundwater studies because groundwater conditions in quality and quantity influenced by the geological formation of rock minerals in aquifer. Naturally, the condition of the research area which consists of peat swamps can also affect the characteristics of groundwater. The aims of this research are to determine groundwater types and groundwater facies in study area with an analytical approach using stiff diagram and piper diagram. The method used was purposive sampling by collecting data from dug wells at the research site. 5 samples from dug wells were used as representatives in the groundwater facies analysis. The groundwater facies analysis was carried out by measuring the concentration of major ions such as Na, K, Ca, Mg, Cl, SO4, and HCO3. The highest groundwater level was in the northern part of study area (7,84 m) while the lowest groundwater level was in the southwest part of study area (2,05 m). The results showed three types of groundwater based on stiff diagram as sodium chloride (NaCl), sodium sulfate (NaSO4) and magnesium sulfate (MgSO4). The lithology conditions that composed the aquifer affected the facies or origin of groundwater. The alluvium layer in the research area which rich in sodium (Na+) minerals with chloride (Cl-) or sulfate (SO42-) anions forms chloride sulfate facies (Cl+SO4) which were located in the middle to the south of the study area and sodium (potassium) chloride (sulfate) facies (Na(K)Cl(SO4)) which were distributed in the northern part of study area.
