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 GIS software were used to evaluate the groundwater vulnerability of Chengting new district in Shijiazhuang, china. The groundwater vulnerability grades of the study area were divided by the model. The research results could provide scientific basis for the new district planning and construction.

Abstract The intrinsic vulnerability of groundwater aquifers refers to their sensitivity to all contamination coming from soil surface irrespective of the nature of the polluting. In order to improve the protection of groundwater, there must be a reduction in the infiltration of contaminants towards the reservoir through the impacting factors determination of this phenomenon by means of research. There are collected models that include particular number of factors which allow the determination of a sign of groundwater vulnerability of all superficial pollutions. The goal of the study centers on ascertaining the state of vulnerability and the risk of groundwater pollution of the Collo region with a new proposed method by Kherici. Generally, assessment methods of vulnerability and the danger of groundwater pollution employ parametric systems with numerical quotation, cartographic superposition where the analytical methods are based on equations. In this study, we consider the combination of criteria dependent on natural factors (thickness of the unsaturated zone, geologic facies, degree of auto-purification) and the causes of groundwater vulnerability to man-made pollution (anthropogenic factors).

Abstract Groundwater is a water resource that is still a mainstay for humans. The need for groundwater increases with the growth of population and the development of the industrial and agricultural sectors. The residents of Kediri City still use wells from shallow aquifers to fulfill their water needs. Shallow aquifers are prone to pollution due to the influence of shallow groundwater depths and human activities. The purpose of this study is to determine the vulnerability of groundwater pollution in Kediri City. Groundwater vulnerability was conducted by the GOD method (Groundwater Occurrence, Overlaying Lithology, and Depth of Groundwater) that consists of 3 parameters, namely the groundwater confinement, the type of overlying strata, and the depth of the groundwater level. The analysis results show that the level of groundwater vulnerability according to the GOD method in Kediri City consists of moderate and high classes. The western and the eastern part of Kediri City is classified as a high level of vulnerability. In contrast, in the middle of Kediri City, it tends to experience a moderate level of vulnerability.

The deleterious impacts of dumpsite activities and the associated risk on both theenvironment and human is consequential, hence this study assessedgroundwater vulnerability to pollution from dumpsite using a modified DRASTICmodel. Six hydrogeological factors: D- Depth to water, R- Net Recharge, AAquifermedia, L- Distance of well to dumpsite, T- Topography, and C- Claycontent were used in the modification (DRALTC) based on peculiarity of thestudy area. Cluster analysis of groundwater data and Water Quality Index (WQI)were also evaluated. The groundwater vulnerability index was characterized bytwo zones; forty five percent (45%) moderate and fifty five percent (55%) highzones. The dendogram showed three clusters of chemical dissimilarities. TheWQI showed values between 61.8 and 205, indicating good, poor and very poorclass of water. The analysis of the groundwater samples showed nitrateconcentration ranging from 7.60 to 35.6 mg/L and from 8.56 to 32.4 mg/L in dryand rainy seasons, respectively. The DRALTC model was validated using nitrateconcentration. Though, there appeared relative groundwater protection fromcontamination, there is still need for measures to mitigate further contaminationand associated risk in the moderate vulnerability zones. DRALTC model is proveda good tool in groundwater management.

Abstract The risk of diffuse pollution of groundwater by nitrogen substances from agricultural land is perceived as a result of the interaction of groundwater vulnerability (determined by the characteristics of the environment overlying groundwater in relation to water transport or soil solution) and loading of overlying environment by nitrogen. Index of groundwater vulnerability was assessed on the basis of four parameters, namely, the amount of effective rainfall in the period from October to March, the capacity of soil to accumulate water, the average depth of the groundwater table and the permeability of the rock environment. Assessment of the index of loading of overlying environment by nitrogen was based on two parameters, namely, nitrogen balance and crop cover on agricultural land in the winter half on districts level in 2012, which corresponds with current state of the load. The resulting risk of groundwater pollution by nitrogen was expressed by the formula counting with the transformed values of groundwater vulnerability index and the index of loading of overlying environment by nitrogen. From practical point of view, the above mentioned indexes, as well as the subsequent risk of diffuse groundwater pollution, were spatially expressed via three associated categories. Based on the evaluation of relevant parameters, 5.18% of agricultural land falls into the category of very high and high risk, 42.20% in the medium risk category and 52.62% in the category of low and very low risk of diffuse pollution of groundwater by nitrogen from agricultural land.

Groundwater is the greatest significant source of water in the Bahr Al-Najaf area. In this research the DRASTIC technique has been utilized, to produce a map of ground water vulnerability for the area. Because of the relation between LULC (Land Use and Land Cover) and groundwater pollution, the LULC map was applied with the standard DRASTIC technique to confirm accuracy of vulnerability for pollution. A LULC map is extracted from Enhanced Thematic Mapper (TM) satellite imagery utilizing several methods in GIS. The LULC map shows that three portions of LULC can be recognized (Agricultural land, Wet land and Barren land). The LULC map was weighted and rated then changed to LULC index map. That index map is a supplementary factor that was combined to the standard DRASTIC technique to modify DRASTIC vulnerability in study area. The final vulnerability was obtained by the DRASTIC technique that varies from (70 to 140). The LULC index map as a modified DRASTIC with ranging of (95-175). The modified LULC of DRASTIC technique has a higher correlation (Pearson’s factor) 0.87 per concentration of nitrate values and is suggested as the best suitable technique to be utilized for the area of study.

Groundwater Sampling

The groundwater vulnerability to pollution refers to the ease of pollutants reaching groundwater, so the groundwater will be polluted. The concept shows a probability that pollution will occured which basically bases on the assumption that the physical environment can prevent the flow of pollutants into the aquifer. The purpose of this study was to predict the vulnerability of groundwater in the study area against pollution. To achieve these objectives beside base on secondary data, also measured the depth of phreatic surface, slope and groundwater sampling. Location of measurement and sampling is determinated by considering location of infiltration measurement ever done by Purnama in 2017. To conduct groundwater vulnerability analysis on pollution in the study area, carried out by SINTACS Method which bases on a numerical system of weight and rating. Weight are determined based on the significance of the effect of the parameters on groundwater pollution, while the rating is determined based on the significance of the influence of variables in each parameters against groundwater pollution. As a result, it is known that groundwater vulnerability indeks in research area range from 117,0 to 189,9. According to criteria of SINTACS, the value are classified as moderate vulnerability and rather high vulnerability. Areas that include moderate levels of vulnerability generally located in Sentolo Formations that consist of limestone and has grumusol soil type. Areas that classified as rather high vulnerability is located in Yogyakarta Formation that consist of volcanic rock and has regosol soil type. Based on this phenomena, it can be said that geological aspect and type of soil greatly affect the vulnerability of groundwater to pollution in the research area.
