GW samples were collected from 32 locations across the municipality's nine administrative wards. The physical parameters, such as total dissolved solids (TDS): 383 ppm, pH: 7.4, and electrical conductivity (EC): 583 μs/cm were reported, respectively. Among the detected chemical components, arsenic (As): 0.16 mg/L, iron (Fe): 0.77 mg/L, and manganese (Mn): 0.75 mg/L were found beyond the standard values. Geospatial analysis and multivariate analyses, such as correlation coefficient analysis (CCA), cluster analysis (CA), and principal component analysis (PCA), were performed to determine the potential sources of contaminants in the GW of the selected study areas. The water quality index (WQI) and heavy metal pollution index (HPI) suggest that most samples are unsuitable for drinking and irrigation. Following the water quality indices, CCA indicates the significant impact of As and Mn on water quality. The CA and PCA suggest geogenic, anthropogenic, and natural processes are mainly responsible for releasing those contaminants in GW.</p></div>","PeriodicalId":100615,"journal":{"name":"HydroResearch","volume":"6 ","pages":"Pages 166-176"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49878904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rainwater is one of the finest boons of the nature which can reduce this problem. To utilize the rainwater properly, it is highly needed to make rainwater harvesting (RWH) structure in these regions. The major goal of this study is to find optimal sites for RWH structures to fulfill meet the needs of fresh water demand in Northwestern region of Bangladesh, by employing a multiple-criteria decision making technique based on geographic information systems. Seven spatial parameters, including, rainfall, land use &amp; land cover, slope, soil texture, road distance, drainage density, physiography were included in this study's site appropriateness analysis for RWH structures. The ultimate suitable map which is acceptable for installing RWH structure had been broken down into four categories such as excellent, good, medium and poor regions. The categories occupy the study area's territory in the following order: 21.94%, 59.57%, 15.93%, 2.16%. The study's excellent appropriateness rating for developing RWH structures includes the districts of Sirajganj, Gaibandha, Kurigram, Rangpur, Thakurgaon, Dinajpur, Panchagar, and Nilphamari, while its low appropriateness index includes Pabna, Natore, Rajshahi, Nawabganj, Naogaon, Joypurhat, and Bogra.

To assess regional and temporal changes, we conducted a trend analysis on mean monsoon rainfall and mean summer temperature in four Indian states with diverse climates: Karnataka, Gujarat, Rajasthan, and Maharashtra. The selection of these states as study areas was based on the monsoon's arrival time from the Arabian Sea. Using nonparametric statistical trend analysis techniques such as the Mann-Kendall test, Sen's slope estimator, Kendall tau and Mann-Whitney-Pettitt (MWP). we examined trends from 1951 to 2000 at a significance level of 5%. Additionally, we employed linear regression to identify climatic patterns. Our findings revealed both positive and negative trends in mean monsoon rainfall and mean summer temperature across all four states. Rainfall trends exhibited a decreasing pattern in all states, except for Maharashtra, which displayed a slightly negative trend despite an overall positive annual temperature trend. Conversely, temperature trends showed an increasing pattern in all states except Maharashtra. To further explore the relationship between summer temperature and monsoon precipitation, we investigated several urban centers within these four states. The results indicated varying trends, including increasing, decreasing, and no discernible trend across different stations. Our analysis demonstrated a general decline in yearly monsoon precipitation across most regions in the four states, coupled with recorded temperature changes. Notably, Karnataka exhibited a stronger positive correlation between rainfall and temperature trends. Maharashtra and Gujarat also exhibited a positive correlation, albeit at a moderate level. Conversely, Rajasthan displayed a very weak correlation (tau = 0.079), indicating no significant relationship between these two climatic parameters.</p></div>","PeriodicalId":100615,"journal":{"name":"HydroResearch","volume":"6 ","pages":"Pages 247-254"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49878869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, As concentration in the groundwater samples (depth: 52–70 m) of southwestern Bangladesh was evaluated using Atomic Absorption Spectrometer (AAS) to know the current status, possible source(s), and probable health risk of As. In addition, the other relevant water quality parameters (pH, temperature, EC, TDS, Na⁺, K⁺, Ca²⁺, Mg²⁺, Cl⁻, NO₃⁻, SO₄²⁻, HCO₃⁻, Fe, and Mn) were also measured using various instruments such as portable bench meter, Flame photometer, AAS, and Ion Chromatograph to evaluate the suitability of the water for drinking and irrigation purposes. Arsenic concentration (μg L⁻¹) ranged from 13.10 to 292 (mean ± SD: 156.9 ± 100.31), which is alarmingly, and 15 times higher than the WHO recommended value for drinking water. pH values of collected groundwater samples ranged from 7.17 to 8.09, which exhibits a lightly alkaline nature. The average abundance of major cation follows the order of Ca²⁺ &gt; Mg²⁺ &gt; Na⁺ &gt; K⁺, and the average abundance of major anions follows the order of HCO₃⁻ &gt; Cl⁻ &gt; NO₃⁻ &gt; SO₄²⁻, with Ca²⁺and HCO₃⁻ being the dominant cation and anion, respectively. Based on water quality assessments utilizing the water quality index and entropy water quality index, the groundwater in the region of interest was not suitable for drinking or irrigation purposes. The Piper tri-linear diagram suggests the dominant water type in the study area was the Ca-HCO₃ type, where Ca and HCO₃⁻ are the principal cations and anions, respectively. A bivariate analysis of different hydro-chemical parameters revealed that silicate weathering controls the hydrogeochemical processes in groundwater. Principal component and hierarchical cluster analysis indicate As in groundwater are geogenic in origin under reductive dissolution processes. The moderate correlation between As, Fe, and Mn indicate reductive dissolution of FeOOH and MnOOH plays a vital role in releasing As from sediment to groundwater.
