Abstract:

Development of agricultural and mining activities and the rapid growth of the population (3.8%) in Oumé’s area, constitute a potential risk of groundwater’s pollutions. This study interested Oumé’s area and aims to elaborate a map of vulnerability to pollution for a better management of groundwaters. The database is constituted by various data in particular, geological, hydrogeological, geomorphological, pluviometric data and satellite image. Methods DRASTIC and GOD were used in this study. Results of DRASTIC method indicated that 31.86% of study area have a very low vulnerability, 68.12% a lo

Abstract The increasing population density can contaminate groundwater. So far, groundwater is still the primary source to fulfill clean water and drinking water in Muntilan, Salam, and Ngluwar Sub-District. Studies on groundwater vulnerability are essential to minimize the contamination risks as a piece of basic information for land use planning. This research aims to assess groundwater vulnerability in Muntilan, Salam, and Ngluwar Sub-District. The simple vertical vulnerability (SVV) method with GIS was selected to develop a groundwater vulnerability map. The parameters of this method consis

This map provided information distribution on the level of vulnerability to groundwater contamination in an area. The impact made considered in making regional decisions to create a sustainable development framework. The DRASTIC method is an instrument for evaluating the vulnerability of groundwater pollution. The DRASTIC methods can use evaluate vulnerabilities of groundwater contamination which seven parameters: the depth of the groundwater table (D), rainPL (R), aquifer media (A), soil textur

Abstract:

The Wonosari Basin and the Gunungsewu Karst Transition Zone have enormous groundwater resources but are hydrogeologically vulnerable to contamination. To achieve sustainable groundwater protection and management, it is imperative to study groundwater vulnerability. Th e research aimed to determine the spatial distribution of groundwater vulnerability in both areas. The COP method, which integrates the concentration of flow (C-Factor), overlaying layer (O-Factor), and precipitation (P-Factor), was used to assess the groundwater vulnerability. Based on the analysis, the groundwater was lowly to

Abstract:

As the Qujing citys industrial development, how to use and protect groundwater is the primary problem of urban development because of the non-uniformity distribution of groundwater. This paper establishes a two-story DRASTIC fuzzy evaluation model using analytical hierarchy process, by Qujing basin groundwater survey and data analysis. The model was applied to evaluate the groundwater vulnerability of Qujing basin and the east and west sides of the mountain with the consideration of depth to the water table, net recharge, aquifer material, soil type, topography, impact of vadose zone and hydra

Abstract:

The Gharb aquifer plays a critical role as a source of drinking water and irrigation in Morocco. However, rapid economic growth and increased use of chemical fertilizers have led to groundwater pollution and land degradation. To address this issue, a vulnerability assessment was conducted using the Susceptibility Index (SI) method. Five parameters including depth to groundwater, effective recharge, slope, soil type, and land use/land cover were considered to evaluate groundwater vulnerability. The vulnerability assessment revealed index values ranging from 31 to 160. The study area was categor

Abstract:

Given the weight in groundwater vulnerability assessment, entropy weight combined with DRASTIC model is considered to assess the groundwater vulnerability. The assessment index weight is assessed by entropy weight and the model is ultimately applied to the assessment on the vulnerability of the groundwater in Weining Plain of Ningxia Hui Autonomous Region. Firstly, based on the seven assessment index attribute partition charts, the assessment index weight is calculated by entropy weight; then, by the ARCGIS grid image overlay tool to overlay the seven index grid images, the composite index cha

Abstract:

Accurate vulnerability assessment methods are essential for effective groundwater management and protection, allowing the identification of areas vulnerable to pollution. The widely used DRASTIC method has been modified to improve groundwater vulnerability assessment in regions where Quaternary sediments form a confining layer above the main useful aquifer. This study applied the modified DRASTIC method to two study areas in Estonia with heterogenous Quaternary sediments. The results were compared to the original DRASTIC method and a groundwater vulnerability assessment method used formerly in

Groundwater contamination is a ubiquitous problem, especially in developing countries such as Indonesia. Groundwater vulnerability assessment is an effective tool that provides information about the status of groundwater and potential contaminants. This approach helps in groundwater conservation and management. This study conducted an intrinsic groundwater vulnerability assessment to anthropogenic contamination in Kasihan, Yogyakarta, Indonesia.

Abstract:

Groundwater is an important component of water resources. Compared with surface water, groundwater has slower flow rate and lower capacity of diluting and self-purification. It is difficult to treat the groundwater pollution. Therefore, it is important to protect the groundwater from being polluted for planning and management of groundwater resources. It is considered as an effective method for decision makers and administrators to identify the high risk level of groundwater pollution through groundwater pollution vulnerability assessment. In this study, the most widely used DRASTIC model and

Abstract:

The possibility of contaminants percolating and diffusing into the groundwater system is referred to as groundwater vulnerability. When groundwater once gets polluted it is very difficult to process/clean it so, measures must be taken to assess the vulnerability of the groundwater for effective groundwater conservation and management planning. This study aims to evaluate and map the vulnerability of Raipur city using the SINTACS and DRASTIC models and to compare their effectiveness between them.

Abstract:

Groundwater vulnerability assessments are vital for protecting valuable resources by revealing susceptibility to contamination. This study developed an enhanced index model to assess the intrinsic vulnerability of a supplied karst aquifer in Qingduo, Henan Province. The model considered the 3-D geological structure and modified indices to account for Northern China’s mild karstification. Emphasizing the absolute infiltration capacity of surface contaminants, the model also integrated the groundwater sources and sinks (SS) index. The vulnerability map revealed that over 60% of the aquifers, inc
