Hydrogeochemical characterization and quality assessment of groundwater resource in Savar - an industrialized zone of Bangladesh.

Savar Upazila in the Dhaka District is a rapidly expanding city with a diverse range of industries and agricultural activities. This expansion poses environmental challenges including the threat to groundwater contamination. Based on these considerations, the objective of this research is to carry out ashallowgroundwater hydrogeochemical characterization and an assessment of the suitablity of the groundwaterfor drinking and irrigational purposes using a geochemical approach, multivariate statistical techniques, and some indices ofgroundwater quality. Thehydrogeochemical analyses of 42 groundwater samples from shallow depths (18 - 76m) showed that the order of concentrations of cations, anions, and metals was Ca2+ > Na+ > Mg2+ > K+, HCO3- > Cl- > SO42- > NO3-, and Cr > As > Pb > Mn > Fe, respectively. Weathering of silicates was found to be the most significant hydrogeochemical process governing the chemistry of groundwater. Cation exchange also plays a significant role in the evolution of thegroundwater chemistry. Principal component analysis and hierarchical cluster analysis suggested that anthropogenic activities are influencing groundwater quality. A drinkingwater quality index map showed that about 91% of the groundwater samples were in the excellent category and suitable for human consumption, with only a few samples exceeding the standards of theWHO and Bangladesh for concentrations ofCa2+, Mg2+, HCO3-, Fe, Mn, and As. An analysis of irrigation quality parameters found that most of the groundwater samples were eitherexcellent or good for agricultural uses, except for one samplein the Tetuljhora Union that was unsuitable based on residual sodium carbonate. This finding may be useful to local governments in understanding the current status of groundwater quality, tracking potential threats of contamination, and initiating appropriate measures for long-term groundwater resource management.

Groundwater Characteristics and Quality in the Cascades Region of Burkina Faso

In the context of low rainfall, groundwater abstraction is the main source of water, especially in rural areas. For better water management, a good knowledge of water resources is necessary. The Cascades region depends, like most regions, on the use of groundwater, especially in rural areas. However, this region has been subject to a strong anthropogenic impact in recent years, in association with mineralization. This study aims to establish the status of groundwater quality in order to strengthen the knowledge of groundwater resources, for better planning of preservation strategies and sustainability of actions. Fifty-eight borehole water samples were collected using techniques and methods for assessing groundwater properties. The results indicate that the electrical conductivity (EC) values of the water show slight mineralization. The waters are aggressive, with severe-to-significant corrosion, and with calcite saturation in relation to the geological facies. Principal component analysis allowed us to conclude that residence time and leaching due to anthropogenic activities have an impact on quality. The chemical and bacteriological quality of the groundwater systems is of great concern, as some parameters exceed the Burkina Faso guidelines.

Groundwater quality status based on a modification of water quality index in an arid area, Iran

AbstractIncreasing population, high demand for food, and uncontrolled abstraction of aquifers have severely affected the water quality. This study aimed to evaluate the water quality of 17 deep agricultural wells in Bahabad plain from the perspective of irrigation and drinking. In order to determine the water quality of wells and analyze the water quality index (WQI), a set of statistical methods such as a fuzzy analytic hierarchy process (FAHP) and TOPSIS were used. WQI is considered one of the primary methods for assessing drinking water quality. Still, due to the discrepancy between the results and the WQI (WHO), it was decided to modify the WQI method. The integrated use of FAHP-WQI and the TOPSIS method led to significant changes in the grading and the classification of water wells. The results showed that these two methods combined could be used as a good and complementary technique to eliminate ranking inconsistencies by WQI. Combining WQI results with GIS also allows for a deeper analysis of drinking water quality. The results showed that most of the water quality problems are due to wells in the northern region of the plain, and more than 41% of wells in this region are not in good condition.

Identification of Groundwater Contamination using MODFLOW: A Case study of Chhatral Area, Gandhinagar

Abstract: In India, groundwater is a primary source of freshwater and used mainly for agriculture and irrigation purposes. Approximately 80% of the population is dependent on groundwater for household and agricultural purposes in India. The pace of urbanization in Gandhinagar has been accelerated since the capital of Gujarat state was formed; hence a study is carried out to identify the status of groundwater quality in the Chhatral area of Gandhinagar city. In this study, MODFLOW and MT3DMS software are used to identify contaminated groundwater status in particular study areas. MODFLOW software helped in simulating ground water quality under various hydro-geological conditions. After the initial simulation, the area was assigned to MT3DMS, a three-dimensional multi-species solute transport model where arsenic and fluoride concentrated chemicals are figured out above the permissible limit authorized by WHO and BIS for drinking purposes. The results of this study demonstrated that there is need to take necessary steps to control ground water quality in the study area. Groundwater quality modelling will help the stakeholders, government organizations & users to get the exact groundwater quality status for future use. Keywords: Groundwater contamination, Arsenic, Fluoride, MODFLOW, and MT3DMS

Impact of climate change on groundwater hydrology: a comprehensive review and current status of the Indian hydrogeology

Groundwater is the second largest store of freshwater in the world. The sustainability of the ecosystem is largely dependent on groundwater availability, and groundwater has already been under tremendous pressure to fulfill human needs owing to anthropogenic activities around various parts of the world. The footprints of human activities can be witnessed in terms of looming climate change, water pollution, and changes in available water resources. This paper provides a comprehensive view of the linkage between groundwater, climate system, and anthropogenic activities, with a focus on the Indian region. The significant prior works addressing the groundwater-induced response on the climatic system and the impacts of climate on groundwater through natural and human-instigated processes are reviewed. The condition of groundwater quality in India with respect to various physicochemical, heavy metal and biological contamination is discussed. The utility of remote sensing and GIS in groundwater-related studies is discussed, focusing on Gravity Recovery and Climate Experiment (GRACE) applications over the Indian region. GRACE-based estimates of terrestrial water storage have been instrumental in numerous groundwater studies in recent times. Based on the literature review, the sustainable practices adopted for optimum utilization of groundwater for different purposes and the possible groundwater-based adaptation strategies for climate change are also enunciated.

The background of this research is that most of the rural communities, one of which is Banyuajuh Village, Kamal, Bangkalan, utilizes clean water sources from ground water. However, people do not pay attention to how to build wells with the characteristics and distance from the pollutant source correctly. Therefore, this study aims to determine the construction and distance of the well from the pollutant source, the quality parameters of Temperature, pH, Turbidity, TDS, CaCOs, and Total Coliform based on the quality standard of the Minister of Health of the Republic of Indonesia No. 32 of 2017 and the water quality index at the research site using the Pollution Index (IP) method by conducting a preliminary survey then followed by sampling 2 times at 3 sampling locations referring to SNI 6989.58 2008 for sample testing. After that, an analysis was carried out using the Pollution Index (IP) method for determining the status of groundwater quality which will be presented in a qualitative descriptive form. Based on the results of the study obtained the result that there was construction and the distance between the well and the pollutant source at location A for the floor of the well, the diameter of the well covering the well, the hoist and the distance between the well and the pollutant source were not qualify. At location B for all constructions and the distance from the well to the pollutant source does not meet the requirements. At location C, the height of the well lip, the diameter of the well, the cover of the well, the hoist and the distance between the well and the pollutant source, do not meet the requirements. The groundwater quality parameters (wells) exceed the quality standards in the form of temperature at locations A1: 29°C, A2 30°C and total coliform parameters at locations A1 21,100 CFU/100m, A2 22,600 CFU/100m, B1: 24,000 CFU/100m, B2 : 24,500 CFU/100m, C1: 180, C2: 840 CFU/100m Meanwhile, the water quality index based on the IP method is moderately polluted at location A (with Plj 8.28) and location B (with Plj 8.16) and lightly polluted at location C (with Plj 4.88).

Impact of road transport on groundwater quality

Road transport is one of the sources of groundwater pollution. The aim of the article is to find out whether the largest roads in Poland have a negative impact on groundwater quality and to assess the extent of their influence. The water chemistry in the area of roads with heavy traffic in north-west and central Poland in 2007–2020 was analyzed. The groundwater quality status and the dynamics of changes in concentrations of selected chemical constituents were assessed. Data was taken from the national chemical monitoring network managed by the Polish Geological Institute - National Research Institute. The results of monitoring tests at 42 selected points were subject to detailed statistical analysis. The mentioned points were located within 100 m from the roads. A statistical analysis of selected chemical parameters and a correlation matrix for selected components were performed. The distribution of electrolytic conductivity in the analyzed 42 points in 2019 is presented in the form of a contour map against the background of the main roads in the analyzed area. Based on archival data, a 7-year prediction of changes in concentrations of selected chemical components, using the autoregressive method, was made. The predicted distribution of concentrations of individual chemical components in groundwater indicates that the vicinity (up to 50 m) of roads may negatively affect the groundwater quality. The increased concentration of chloride and sodium ions was found in most sites. An upward trend was also observed for specific electrolytic conductivity.

Arsenic Contamination in Groundwater and Potential Health Risk in Western Lampang Basin, Northern Thailand

This research aimed to investigate the spatial distribution of arsenic concentrations in shallow and deep groundwaters which were used as sources for drinking and domestic and agricultural uses. A geochemical modeling software PHREEQC was used to simulate equilibrium geochemical reactions of complex water–rock interactions to identify arsenic speciation and mineral saturation indices based on groundwater quality and hydrogeochemical conditions. In addition, the potential health risk from arsenic-contaminated groundwater consumption was assessed based on the method developed by the U.S. Environmental Protection Agency. The study area is located at the western part of the Lampang Basin, an intermontane aquifer, Northern Thailand. The area is flat and situated in a floodplain in the Cenozoic basin. Most shallow groundwater (≤10 m depth) samples from dug wells were of Ca-Na-HCO3 and Ca-HCO3 types, whereas deep groundwater from Quaternary terrace deposits (30–150 m depth) samples were of Na-HCO3 and Ca-Na-HCO3 types. High arsenic concentrations were found in the central part of the study area (Shallow groundwater: <2.8–35 mg/L with a mean of 10.7 mg/L; Deep groundwater: <2.8–480 mg/L with a mean of 51.0 mg/L). According to geochemical modeling study, deep groundwater contained toxic As(III), as the dominant species more than shallow groundwater. Arsenic in groundwater of the Lampang Basin may have been derived from leaching of rocks and could have been the primary source of the subsurface arsenic in the study area. Secondary source of arsenic, which is more significant, could be derived from the leaching of sorbed arsenic in aquifer from co-precipitated Fe-oxyhydroxides in sediments. Quantitative risk assessment showed that the average carcinogenic risk values were as high as 2.78 × 10−3 and 7.65 × 10−3 for adult and child, respectively, which were higher than the acceptable level (1 × 10−4). The adverse health impact should be notified or warned with the use of this arsenic-contaminated groundwater without pre-treatment.

A mathematical approach to groundwater quality and pollution of Adyar sub-basin, Tamil Nadu, India

The quality of drinking water sources in the Adyar river sub-basin of northern Tamil Nadu is assessed in this study. This research uses a combined water quality index (WQI) and pollution index (PI) to assess and characterise groundwater quality. Water samples will be collected from nine locations in the study area for the assessment. The water quality index was calculated based on Total Dissolved Substances (TDS), Nitrogen oxides (NOx), Calcium (Ca), Magnesium (Mg), Sodium (Na), Potassium (K), Chloride (Cl), Sulphate (SO4), Bicarbonate (HCO3), Fluoride (F), Power of Hydrogen (pH) and Electrical Conductivity (EC). These twelve parameters were analysed and characterised according to standard methods and the Indian standard, which were then used in calculating the water quality index. Groundwater quality and pollution status of the Adyar river basin were assessed using the Groundwater quality index and comprehensive pollution index for the years 1990, 2005, and 2020. A result reveals that the groundwater quality has decreased from 1990 to 2020. Around seven parameters exceeded the permissible limits in 1990, nine parameters exceeded the permissible limits in 2005, and around eight parameters exceeded the allowable limits in 2020. The pollution status of the groundwater has considerably reduced from 1990 to 2020. Eastern parts of the study area were highly polluted and had low groundwater quality.

Groundwater quality assessment for drinking and industrial purposes in transboundary aquifers of Gurdaspur district, Punjab, India

ABSTRACT The study of groundwater quality for drinking and industrial usage is critically important for the conservation and sustainable management of groundwater resources. The main purpose of this study was to evaluate the drinking and industrial groundwater quality status of five blocks of Gurdaspur district, Punjab, India, falling along international boundary of India–Pakistan thus serving as transboundary aquifers, by investigating spatial distribution of drinking and industrial groundwater quality indices using GIS approach. To study the drinking water quality, Groundwater quality index (GWQI) method was applied. The spatial distribution map of GWQI showed that the groundwater quality was poor in the Dera Baba Nanak block as compared to the other blocks. Further, corrosion and scaling indices namely Langelier saturation index (LSI), Aggressive index (AI), Ryznar stability index (RSI), Puckorius index (PI) and Larson-Skold index (LS) were calculated with the help of water quality parameters of all the samples. LSI, AI and RSI indicated the scaling tendency of sampled groundwater while, the other two indices, PI and LS suggested the corrosive behaviour of majority of the sampled groundwater. The findings of GWQI and industrial indices indicated that the groundwater quality was by and large not suitable for drinking and industrial usage in some areas. Therefore, regular and appropriate monitoring of groundwater quality is suggested in the study area and particularly in the regions where groundwater quality issues are reported so as to sustainably manage the groundwater resources.

Groundwater quality assessment for irrigation use in the Godavari Delta region of east coast India using IRWQI and GIS

Abstract The present work was carried out in the deltaic region of the river Godavari in coastal Andhra Pradesh of southern India to evaluate the status of groundwater quality for irrigation. Groundwater is predominantly used in these productive agricultural fields. Saline water intrusion in fresh groundwater aquifers, which is mainly due to the excess withdrawal of groundwater, was recorded in the study area. A total of 80 groundwater samples were analyzed for physical and chemical parameters using standard chemical procedures. The groundwater mainly represents Na+–Cl− type, which shows the mixing of fresh water with saline water. The high correlation between Na+–Cl− and Mg2+–HCO3− explained that the intermixing of aquifer waters and the leaching of secondary salts influenced the region. Evaporation-fractional crystallizations are the main processes in the groundwater of the study area. The irrigation water quality index was calculated using different quality indices including Na%, sodium adsorption ratio, residual sodium bicarbonate (RSBC), permeability index (PI), magnesium hazard (MH), Kelly's ratio (KR), and potential salinity (PS), Cl−:HCO3−, Mg2+:Ca2+ and Na+:Ca2+ to estimate the suitability of groundwater quality for irrigation. Spatial distribution maps were prepared using raster interpolation in GIS. The assessment revealed that the areas covering 67.6% of electrical conductivity, 100% of total dissolved solids, 57.5% of Na%, 21.3% of RSBC, 66.3% of PI, 16.3% of MH, 65% of KR, and, 100% of PS required severe to moderate restrictions. Overall, the groundwater in the study region showed potential salinity due to geogenic and anthropogenic activities, and thus it must be monitored for sustainable agriculture.

Evaluation of Groundwater Suitability for Irrigation and Drinking Purposes in an Agricultural Region of the North China Plain

Groundwater is an irreplaceable resource for irrigation and drinking in the North China Plain, and the quality of groundwater is of great importance to human health and social development. In this study, using the information from 59 groups of groundwater samples, groundwater quality conditions for irrigation and drinking purposes in an agricultural region of the North China Plain were analyzed. The groundwater belongs to a Quaternary loose rock pore water aquifer. The depths of shallow groundwater wells are 20–150 m below the surface, while the depths of deep groundwater wells are 150–650 m. The sodium adsorption ratio (SAR), sodium percentage (%Na), residual sodium carbonate (RSC), magnesium hazard (MH), permotic index (PI) and electrical conductivity (EC) were selected as indexes to evaluate the shallow groundwater suitability for irrigation. What’s more, the deep groundwater suitability for drinking was assessed and the human health risk of excessive chemicals in groundwater was studied. Results revealed that SAR, Na% and RSC indexes indicated the applicability of shallow groundwater for agricultural irrigation in the study area. We found 57.1% of the shallow groundwater samples were located in high salinity with a low sodium hazard zone. The concentrations of fluorine (F−) in 79.0% of the deep groundwater samples and iodine (I−) in 21.1% of the deep groundwater samples exceeded the permissible limits, respectively. The total hazard quotient (HQ) values of fluorine in over half of the deep groundwater samples exceeded the safety limits, and the health risk degree was ranked from high to low as children, adult females and adult males. In addition to natural factors, the soil layer compression caused by groundwater over-exploitation increased the fluorine concentration in groundwater. Effective measures are needed to reduce the fluorine content of the groundwater of the study area.

A novel approach to baseline water quality assessment at local and catchment scale: a case study from Berambadi, India.

Optimal design and maintenance are necessary for the sustainability of wastewater treatment systems. In this study, we present the outcome of a novel approach to baseline assessment conducted prior to the design and deployment of a decentralized wastewater treatment system at a school in rural India. The baseline water quality monitoring protocol was deployed to assess (a) the quality and quantity of wastewater (greywater and blackwater) flows from the school and (b) the status of surface water and groundwater quality in the catchment. Hourly greywater flows and water quality trends were monitored across four seasons at the school. Average freshwater consumption at the school was 518 ± 322 L/day for hand washing and 287 ± 97 L/day for cooking meals. Greywater generation showed high hourly variations in COD levels. Greywater generated from hand wash and kitchen sources contributed to 110g/day and 96g/day of BOD5 respectively and 214g/day and 141g/day of COD respectively. Based on additional data from a self-reporting sanitation survey, the organic contaminant load generated from the toilet was estimated to be 1.5 ± 0.1kg COD/day. At the catchment scale, both groundwater and surface water quality were monitored seasonally to assess the impact of raw sewage and stormwater inputs. Compared with borewells, high nitrate-N levels (> 10mg/L) were observed in the village hand pump samples throughout the year. Maximum nitrate-N (16mg/L) and fecal coliforms (3.9 log MPN/100mL) levels were observed in surface waters during monsoons, indicating the impact of sewage and surface runoff on water quality. The proposed approach is useful to estimate data on freshwater use and wastewater generation at the school and hence to make the case for, and design of, a sustainable water management intervention.

Health Risk of the Shallow Groundwater and Its Suitability for Drinking Purpose in Tongchuan, China

Studying the quality and health risks of groundwater is of great significance for sustainable water resources utilization, especially in arid and semi-arid areas around the world. The current study is carried out to evaluate the quality and potential health risks of groundwater in the Tongchuan area on the Loess Plateau, northwest China. Water quality index (WQI) and hydrochemical correlation analysis were implemented to understand the status of groundwater quality. Daily average exposure dosages through the oral and dermal contact exposure pathways were taken into consideration to calculate the health risks to the human body. Additionally, graphical approaches such as Piper diagram, Durov diagram and GIS mapping were used to help better understand the results of this study. The WQI approach showed that 77.1% of the samples were of excellent quality. The most significant parameters affecting water quality were NO3−, F−, and Cr6+. The health risk assessment results showed that 27.1% and 54.2% of the samples lead to non-carcinogenic risks through oral intake for adults and children, respectively. In contrast, 12.5% of the groundwater samples would result in carcinogenic risks to the residents. This study showed that the WQI method needs to be supplemented by a health risk evaluation to obtain comprehensive results for groundwater quality protection and management in the Tongchuan area.

All the analyzed parameters were compared with national and international drinking and irrigation water quality standards to understand the overall groundwater quality status of the study area. The study showed that the water samples of almost all the locations were suitable for consumption and irrigation.

Source apportionment and natural background levels of major ions in shallow groundwater using multivariate statistical method: A case study in Huaibei Plain, China

Understanding the sources, natural background levels (NBLs), and threshold values (TVs) of the major ions in groundwater is essential for the effective protection of water resources. In this study, a total of 70 shallow groundwater samples were collected in Suzhou, Huaibei Plain, China. A variety of statistical methods and cumulative probability distribution techniques were performed to identify the sources, NBLs, and TVs of the major ions. The major ion concentrations found in decreasing order as follows: HCO3− > SO42− > NO3− > Cl− and Na+ > Ca2+ > Mg2+. Piper diagram for hydrochemical types shows that groundwater types were Mg–HCO3 (36%), Ca–HCO3 (34%), and Na–HCO3 (30%). According to the factor and the Unmix model analysis, anthropogenic (agriculture-related) and geogenic source (water–rock interactions-related) were identified to be responsible for the chemical composition of the groundwater in the study area, and their mean contributions for the major ion concentrations are 47.9% and 52.1%, respectively. The NBLs for Na+, Ca2+, Mg2+, Cl−, SO42−, and NO3− were determined to be 29.5–44.2, 26.2–38.9, 18.9–39.5, 1.0–9.9, 12.9–19.4, and 2.1–16.5 mg/L, respectively, and the TVs were calculated as 122.1, 169.5, 39.5, 129.6, 134.7, and 18.3 mg/L, respectively. Moreover, this study shows the feasibility and reliability of using these multivariate statistical methods and natural background levels to evaluate the status of groundwater quality.

Identification of Seawater Intrusion in Kota Lama Semarang and Surrounding Based on Geoelectrical Resistivity Survey

Kota Lama Semarang is a tourism potential that causes a high demand for groundwater, which can cause seawater intrusion. Seawater intrusion can affect groundwater quality and soil conditions. This research aimed to determine the depth and distribution of seawater intrusion in the Kota Lama Semarang and surrounding. The research used electrical resistivity tomography (ERT) and vertical electrical sounding (VES). Geoelectrical resistivity surveyed consist of 4 ERT lines and 3 VES lines with a line length was 100 to 160 m. Lines were scattered north and south of the Kota Lama to determine the distribution of seawater intrusion. Inversion processing used Progress for VES and Res2DInv for ERT. The content of chloride as well in Kota Lama was measured as supporting data. At this location it was estimated that it has 3 layers: top soil, sand and sandy clay. The sand layer at a depth of 3 to 11 m was the layer affected by seawater intrusion. Seawater intrusion on the north side was higher than on the south side. This was indicated by the lower resistivity value of the groundwater layer on the north side. The resistivity value of the groundwater layer on the north side was 0.96 Ωm while the south side was 3.76 Ωm. This result was appropriate to the chloride content which indicates a higher concentration on the north side of the Kota Lama Semarang.
