“…The Ca content is higher than the SO4 ion content, and the Cl content is more than Na. Generally, HCO3 in groundwater systems indicates the type of fresh water, while higher Cl-concentrations are influenced by seawater in coastal areas [26].This is also supported by the relatively low electrical conductivity value with an average of 512 μmhos/cm, indicating that the sample is freshwater [27]. The groundwater tested in this study is included in the bicarbonate category because it has the dominant ion, namely HCO3[28].…”

The uncontrolled underground water exploitation and inadequate domestic and industrial wastewater control systems have contributed significantly to groundwater degradation. The groundwater degradation potentially initiates the seawater intrusion especially on the coastal area. The present study aims to analyze the seawater intrusion using geophysical and geochemical approach in the coastal area of Belawan and Medan Industrial Area which close to the coastal area. 15 borehole water samples collected were analyzed to determine anions, cations concentrations, and facies. The results showed that the lithostratigraphy of the study area consisted of alluvial in form of watery gravel and clay layers. The investigation of the groundwater using the geoelectricmethod showed that the resistivity values for track 1 (GL-1) and track (GL-02) are 129Ω to 371Ω. These values are interpreted as layers of sand that have experienced seawater intrusion at a depth of 40-60 meters. Furthermore, the water quality tests at the point of wells 1 and 2 on the chloride parameter, where the highest chloride concentration with values of 205.8 mg/l and 203.2 mg/l, was polluted. The result proved that the seawater intrusion has stimulated the groundwater in the coastal area of Belawan and Medan Industrial Area, Indonesia.

“…The value of Cl determined the anion compound predominating the study area with an average of 453.84 mg/L in 2015. The maximum Cl concentration was observed throughout Pademawu coastline where salt drying pond area does exist (Gemilang & Bakti, 2019). This makes a consideration that the origin of Cl is yielded from salt deposit infiltrating groundwater and caused by other anthropogenic activities ( Selvam et al, 2018).…”

“…Based on the correlation between TDS vs Cl, TDS vs HCO3, and Na vs Cl, it showed a strong relationship with a correlation value almost 1. Therefore, it is interpreted that the groundwater in the study area is highly influenced by seawater yielded from salt pond infiltration (Gemilang & Bakti, 2019). The amount of adsorbed water to the surface of earth mainly relies on rainfall intensity, soil permeability, and land use type (Gopinath et al, 2021).…”

“…On the other hand, anthropogenic activities also play a significant role in polluting shallow groundwater aquifers, such as household, agriculture, and husbandry waste directly impacting the low quality of groundwater. The presence of salt agriculture is currently reported to enhance salinity in settlement artesian wells due to infiltration processes of saltwater to the shallow aquifer Gemilang & Bakti, 2019).…”

Surface Groundwater Pollution Dynamics Over 2015-2020 in the Salt Drying Pond of Pademawu Subdistrict, Madura, Indonesia

Pamekasan coastal area is the center of salt production concentrated in the Pademawu subdistrict with the ponds area of 740.96 ha. The sufficiently close distance of salt ponds to settlement areas allows several issues, such as shallow groundwater salinization. This study aimed to determine the salt pond’s degradation over five years (2015-2020) and its influence on the salinization issue in Pademawu. We compare groundwater quality parameters (conductivity, TDS, the depth of shallow surface groundwater, and salinity) surveyed in 2015 and 2020, correlated to salt pond area alterations. Over five years of measurement, it was found that conductivity declined, reaching 2779.94 µS/cm. Based on TDS deterioration, groundwater transformed from brackish to freshwater in 2020. By contrast, the depth of shallow groundwater-surface increased by almost one meter. The freshwater area also increased by 22% over five years based on conductivity classification. Groundwater quality dynamics are related to the alteration of the salt pond area. On the other hand, the significant increase in rainfall intensity, which is not beneficial for salt agriculture, results in the salt pond area deterioration, thereby declining surface groundwater salinity in Pademawu due to the less interaction between Cl and groundwater within aquifers. Although the groundwater pollution induced by seawater intrusion and salinization declined in 2020, re-organizing the distance between salt ponds and the settlement area in Pademawu is crucial to minimize further groundwater pollution.

“…The Pademawu Subdistrict is the center of salt farming area because of its gentle slope and proximity to the beach, allowing the seawater to easily transfer to the salt ponds via tidal fluctuations (Efendy et al 2014). The rapid transformation from land into salt ponds triggers several adaptations, such as groundwater pollution and salinization (Citrayati et al 2008), which impact the deteriorating quality of the water consumed by local communities (Gemilang and Bakti 2019).…”

The Pademawu coast has rapidly transformed into salt ponds, causing seawater intrusion and pollution. This study aims to examine the quality of groundwater in the surrounding settlement area of Pademawu and assess its eligibility for daily use. The psychochemical parameters of groundwater are measured in situ. Groundwater samples from several stations are analyzed in the laboratory and used to collect several chemical compounds, including Ca2+, Mg2+, Na+, K+, HCO3-, Cl-, SO42-, Fe2+, Mn2+, F-, NO2-, NO3, and CaCO3. The detected concentrations are then used to calculate TH, sodium adsorption ratio (SAR), %Na, PI, KR, and MH. Hydrochemical calculation and interpretation are also performed. The groundwater characteristics are determined according to TDS, conductivity, and water quality index (WQI). Results showed that the groundwater facies are predominated by Ca-HCO3 (50%) in the northern and middle study areas and Na-Cl (37%) in the salt farming area. The groundwater is categorized as SAR (C2S1) in the north and SAR (C4S2) in the south. The primary groundwater consists of Na+ and Cl- (dominant cation and anion) originating from salt farming. The TDS in the salt farming area ranges from 1000 mg/L to 3000 mg/L (slightly saline). The WQI ranges from 39.0 to 735.4, which encompasses excellent water, good water, very poor water, and unsuitable for consumption. Salt farming infiltration toward unconfined aquifers is the primary factor causing groundwater pollution. Mitigation efforts to minimize scattered infiltration must be applied in the Pademawu Subdistrict by modifying the system between salt farming and settlement areas.
