Abstract Groundwater resources are vital for residents in Muntilan Sub-District and its surrounding area in Central Java. The residents use groundwater for daily consumption by developing dug wells. Therefore, groundwater sources from contamination should be protected to guarantee sustainable groundwater use in this area. Groundwater vulnerability maps can be used as basic information to prevent groundwater contamination, land-use planning, and groundwater resources management. Therefore, this study aims to develop the groundwater vulnerability map in the Muntilan, Salam, Ngluwar Sub-Districts, Magelang Regency, Central Java. The vulnerability assessment used the DRASTIC method. The method has used the sum of the weighting of various parameters, including topography, net recharge, groundwater depth, the impact of the vadose zone, soil media, hydraulic conductivity of the aquifer, and aquifer media. The analysis results described that the DRASTIC Index (DI) value ranges from low to high levels, low levels, and the moderate level of vulnerability covers Muntilan sub-district and salam sub-district, while high levels of vulnerability are located in Muntilan, Ngluwar, and Salam Sub-Districts. Therefore, this vulnerability can be used for regional spatial planning and groundwater protection in the district.

The Impact

Groundwater vulnerability mapping is largely used as a modeling tool to delineate areas susceptible to pollution and to protect groundwater resources from this threat. The Zeuss-Koutine aquifer, which constitutes an important source of drinking water in the Southeastern Tunisia, is subjected to an intensive exploitation and threatened by pollution due mainly to the industrial zone of Koutine. The groundwater circulates in fissured and karstified limestone. Aquifer vulnerability has been assessed using the SINTACS method. The different parameters of the SINTACS model were collected from several sources and converted into thematic maps using ArcGis. Each SINTACS parameter was assigned a weight and rating based on a range of information within the parameter. The weight of each parameter depends on the impact of potential pollution. The analysis of vulnerability map to pollution shows that the Southeastern part of the aquifer and the Wadis beds are more susceptible to pollution. The measured nitrate concentrations of two sampling campaigns carried out in high and dry water seasons are coherent with the SINTACS model results.

Abstract The groundwater vulnerability assessment is normally applied to rural watersheds. However, urbanization modifies the hydrogeological processes. A modified DRASTIC model was adopted to establish a groundwater vulnerability map in an urbanized watershed. The modified DRASTIC model incorporated a land-use map, and net recharge was calculated taking into account the specificity of the urban hydrogeological system. The application of the proposed approach to the Mannouba watershed demonstrates that the groundwater vulnerability indexes range from 80 to 165. The study's results shows that 30 percent of the Mannouba watershed area has a high vulnerability index, 45 percent of the area has a medium index, and 25 percent of the study area has a low vulnerability index. To specify the effect of each DRASTIC factor on the calculated vulnerability index, sensitivity analyses were performed. Land use, topography, and soil media have an important theoretical weight greater than the effective weight. The impact of the vadose zone factor has the most important effective weight and affects the vulnerability index. The sensitivity assessment explored the variation in vulnerability after thematic layer removal. In this analysis, the removal of hydraulic conductivity and impact of vadose zone modified the vulnerability index. Groundwater vulnerability assessment in urbanized watersheds is difficult and has to consider the impact of urbanization in the hydrogeological parameters.

Abstract. The present study estimates the Kerman–Baghin aquifer vulnerability using DRASTIC and composite DRASTIC (CDRASTIC) indices with the aid of geographic information system (GIS) techniques. Factors affecting the transfer of contamination, including water table depth, soil media, aquifer media, the impact of the vadose zone, topography, hydraulic conductivity, and land use, were used to calculate the DRASTIC and CDRASTIC indices. A sensitivity test was also performed to determine the sensitivity of the parameters. Results showed that the topographic layer displays a gentle slope in the aquifer. Most of the aquifer was covered with irrigated field crops and grassland with a moderate vegetation cover. In addition, the aquifer vulnerability maps indicated very similar results, identifying the north-west parts of the aquifer as areas with high to very high vulnerability. The map removal sensibility analysis (MRSA) revealed the impact of the vadose zone (in the DRASTIC index) and hydraulic conductivity (in the CDRASTIC index) as the most important parameters in vulnerability evaluation. In both indices, the single-parameter sensibility analysis (SPSA) demonstrated net recharge as the most effective factor in vulnerability estimation. According to the results, parts of the studied aquifer have a high vulnerability and require protective measures.

Abstract Toxicity due to the presence of heavy metals in ground and surface water due to the release of effluents from industries holds the potency to cause temporary or permanent damage to the living organisms in the near vicinity of these industries. This paper aims to assess the vulnerability of groundwater resources owing to its contamination in Banthar Industrial Area. Using DRASTIC model in combination with Quantum Geographic Information System (QGIS), a groundwater vulnerability map was developed, which indicated that the dispersal of Chromium was in the range of 300–1000 µg/l. In order to study the impact of Chromium dispersion, the authors proposed a batch adsorption testing of the Hexavalent Chromium (Cr (VI)) using different bio-adsorbent materials, keeping a pH range of 3–9 and the contact time between 0–80 minutes. Adsorption isotherms and Kinetic studies were also considered. All adsorbents followed the Langmuir isotherm (R2 > 0.986), whereas Temkin isotherm stated the affinity of the adsorbents for the Cr (VI). The reactions between Chromium and the bio-adsorbents were found to follow pseudo-second order kinetics, which indicated that the reactions were exothermic. The results proposed that a modification in the bio-adsorbents caused an enhancement in the percent adsorption of Cr (VI) in comparison to the natural available bio-adsorbents.

The demand of groundwater has significantly increased during the past two decades to meet the food and fiber requirements due to constrained surface irrigation water. The groundwater has a major share to grow agriculture in Punjab-Pakistan, which produces more than 90% gains of the country. Beside the importance of groundwater, a major concern in recent years is the contamination of groundwater. The consecutive monitoring and mapping of aquifer water quality in large areas is a hectic job and not even economically feasible. Thus groundwater vulnerability maps are becoming more in demands to represents regional aquifer contamination potential. The aim of this research work was to find out the groundwater vulnerability potential zones in Faisalabad and its nearby areas, which is the fastest growing city of Pakistan. For this purpose, GIS based DRASTIC model was used to measure vulnerability related to agriculture in Faisalabad district. The inputs of the model are based on seven different layers. The results of the model were compared with groundwater samples. It was found that the DRASTIC model accurately identified the vulnerability of Faisalabad District with prediction efficiency of about 73%. The results revealed that more than 30% of study area was under high vulnerability potential. The areas under high vulnerable pollution are located in middle and upper part of Faisalabad District. The high vulnerable pollution in surrounding of Salarwala, Chak Jhumra and Khurianwala cities was due to shallow groundwater table, high recharge, gradual slope, sandy aquifer media and soil media consist of medium sand. The high vulnerable pollution in surrounding of Dijkot city was due to shallow groundwater table, gradual slope, vadose zone consist of course sand and high hydraulic conductivity. It is therefore recommended that Rainwater harvesting and ASR (Aquifer Storage and Recovery Wells) should be adopted in medium and high vulnerability areas to reduce water salinity.

The Impact

<p>Groundwater is vulnerable and more susceptible to contamination from various anthropogenic elements. Various steps are taken to measure the groundwater vulnerability for a sustainable groundwater development. The present study estimates the aquifer vulnerability by applying DRASTIC model in the Geographic Information System (GIS) environment. The DRASTIC model uses seven hydrological parameters which include depth to water level, net recharge, aquifer media, soil media, topography, the impact of vadose zone and hydraulic conductivity. DRASTIC index was calculated from DRASTIC model that ranged from 31 to 154. All these parameters characterize the hydrological setting for evaluating aquifer vulnerability. Sensitivity analyses have also been performed to determine the sensitivity of every individual DRASTIC parameter towards the aquifer vulnerability. Sensitivity analysis indicated that all the parameters have an almost similar influence on vulnerability index. Depth to water parameter inflicts larger impact on aquifer vulnerability followed by recharge, topography and soil Media. The whole of Kodaganar basin is classified into very low, low, moderate and high vulnerable zones. Nearly three- fourth of the basin has very low and low vulnerability. Incorporating DRASTIC model in the GIS environment has proved efficient in handling large volumes of data and in determining the groundwater vulnerability. </p><p> </p><div class="page" title="Page 1"><div class="section"><div class="layoutArea"><div class="column"><p><strong>Evaluación basada en el Sistema de Información Geográ ca a la vulnerabilidad de un acuífero a partir del método DRASTIC: caso de estudio en la cuenca Kodaganar </strong></p><p><strong><br /></strong></p><p><strong>Resumen</strong></p><p>El agua subterránea es vulnerable y más susceptible a la contaminación de varios elementos antropogénicos.

Este trabajo estima la vulnerabilidad del agua subterránea por la aplicación del método DRASTIC en el entorno del Sistema de Información Geográfica (GIS, en inglés). El método DRASTIC utiliza siete parámetros hidrológicos: profundidad del agua subterránea, recarga neta, litología del acuífero, tipo de suelo, topografía naturaleza de la zona no saturada y conductividad hidráulica del acuífero. El índice DRASTIC fue calculado a través de este método y que oscila entre 31 y 154 unidades. Estos parámetros caracterizan la configuración hidrológica para la evaluación de vulnerabilidad del acuífero. También se realizaron los análisis de susceptibilidad para determinar la respuesta de cada parámetro DRASTIC frente a la vulnerabilidad del agua subterránea. El análisis de susceptibilidad indicó que todos los parámetros tienen una influencia similar en el índice de vulnerabilidad. El parámetro de profundidad ocasiona un mayor impacto en el índice de vulnerabilidad, seguido por la recarga, la topografía y el tipo de suelo. Toda la cuenca de Kodaganar se clasifica en zonas de vulnerabilidad muy baja, baja, moderada y alta. La incorporación del método DRASTIC en el entorno GIS prueba la e ciencia en el manejo de grandes volúmenes de información y en la evaluación de vulnerabilidad de aguas subterráneas.</p>

AbstractGroundwater resources in the south Darb El Arbaein are currently threatened by agricultural impact and rock water interaction associated with over exploitation. Planning of Nubian sandstone aquifer is required, especially in this new invest area. It is implemented by GIS to establish vulnerability areas and to evaluate protocol plans for hydrogeological parameters and soil. The TDS concentration ranged from 750 to 1350 ppm, confirms the impact of non-point source (agricultural activity). It is because recharging Nile water has TDS concentration of 100–300 ppm. Aquifer vulnerability delineation areas by lithogenic and anthropogenic sources have been recently highlighted for water resources systems planning and management. The correlation among hydrogeological, geological, and hydrogeochemical characteristics was discussed and achieved. Ten stratified beds were matched by GIS with specified average weights to them according to their relative importance for groundwater vulnerability. The chosen layers are TDS, aquitard thickness, water depth, hydraulic conductivity, transmissivity, slope, total hardness (TH), sodium adsorption ratio (SAR), discharge rate (Q), and screen length. The groundwater impact distribution reflect five categories ranged from no to excellent aquifer potential levels. Class I (very low vulnerability) was in the northern part and contains 11.1% (16.02 km2) of the area. While very high vulnerability (class V) was in southeast, east, it represents 10.4% (14.96 km2). The preferred invested area was northeast rather than other areas; otherwise, the groundwater degradation enhanced. The vegetation/ or barren lands were established by band 4/band 3, band 3/band 4 ratios and composite RGB 7, 4, and 1 satellite images.

Este estudio se realiza con el  n de establecer los posibles efectos de las actividades de producción de energía y minería en las fuentes hídricas de la zona. Se elaboró un mapa de vulnerabilidad para las fuentes de agua subterránea en varias regiones del país, incluida el área de estudio. La iniciativa de este trabajo es determinar la vulnerabilidad si se remueve el lecho rocoso del esquisto bituminoso, que funciona como una capa de con namiento. Los resultados obtenidos evidencian que el esquisto bituminoso se torna bastante vulnerable a las actividades humanas debido a la presencia de estructuras geológicas, mientras que su vulnerabilidad es media o baja en aquellos lugares donde no hay estructuras geológicas. Además de los rasgos estructurales, existe la posibilidad de que la minería del esquisto bituminoso en las áreas de a oramiento podría descender hasta la capa freática y allí afectar los valores de vulnerabilidad.</p>

Water resources are essential to support everyone in the world, and one of its sources is groundwater. Many areas in Indonesia rely on groundwater to meet their daily needs due to the lack of surface water resources. However, not all-districts have detail information about groundwater resources such as in Tegal District, Central Java Province, Indonesia. Land use planning without the support of information on water resources will cause many problems. Therefore, this study aims to assess groundwater resources in Tegal District using the geoelectrical method and slug test. The research was conducted by geoelectrical survey in 8 locations, measuring groundwater level from the nearest point, and two slug tests. The result of the survey shows that five types of materials in the area are clay, silt, sand, breccia, and lava. The sand layer is an aquifer, and it consists of two layers. The sand layer has a permeability of 6.68 m d–1. However, the clay has a permeability of 1.46 × 10-3 m d–1. The moderate potential of groundwater resources with transmissivity value of more than 50 m2 d–1 lies in the middle of the district.
