The threat posed by illegal mining to the quality of water resources in Ghana has become a major public concern due to the closing down of some water treatment plants in the country. This study aimed to investigate heavy metal pollution in Fena River due to the illegal mining activities. The study was based on 72 samples from six sampling points for a period of 12 months (January–December). Six heavy metals such as lead (Pb), cadmium (Cd), copper (Cu), mercury (Hg), iron (Fe), and zinc (Zn) in water were investigated from Fena River in the Amansie Central District in the Ashanti Region of Ghana. The ranges of the heavy metals in water were BDL–1.041, 0.01–0.703, BDL–0.24, 0.17–16.43, 0.46–1.02, and BDL for Pb, Cd, Cu, Fe, Zn, and Hg. Three metals exceeded the safe drinking water guidelines making water generally unsafe for drinking and domestic purposes. According to Nemerow’s pollution index results, three metals, namely, Cd, Pb, and Fe, were the principal metal pollutants in the study area, whereas Hg, Cu, and Zn were found not to contribute to the pollution effect. However, of the polluting metals, only Cd polluted all the six sampling sites, whereas Pb polluted five out of the six sampling sites. The most striking of the results is the absence of mercury in all the sites studied. The findings from the water quality index confirm that only two of the sites recorded marginal water quality, whereas the remaining four sites recorded poor water quality. The high levels of heavy metals polluting water and the deteriorating water quality are due to the illegal mining activities occurring within and around Fena River.

Introduction: Inappropriate management of mining activities may bring about water pollution and pose a heavy complication on aquatic ecosystem and humans. The study aimed to evaluate the effect of Qorveh gold mining activities on the quality of nearby groundwater. Materials and Methods: The concentration of seven eco-toxic metals along with some general hydrochemical parameters were investigated for 27 sampling stations in the study area using Atomic Absorption Spectrometry (AAS) and conventional hydrochemical methods. The analysis results were further applied to compute pollution indices, namely heavy metal pollution index (HPI) for irrigation purposes. Results: The main elements were within the World Health Organization (WHO) and Iranian National Water Standards (INWS) for irrigation water quality, except for NH4+ in some sampling points. The concentration of heavy metals followed the order Cu > Zn > Pb > Hg > Cd > As. The contents of Hg, As, Cd, and Cu in most sites were higher than the recommended values. Except for two stations, the value of HPI based on the mean concentration was found to be far beyond the critical pollution index value of 100, suggesting that the area is highly polluted with some heavy metals. Conclusion: Elevated concentration of trace elements found in groundwater of this area represented the release of harmful elements from gold mining activities on surrounding environment.

Abstract The existence of river environmental components or sediment and river pollutions are influenced by domestic, industrial, and agricultural waste, it will reduce water quality. The purpose of this study was to determine the index of water quality and sedimentation due to anthropogenic activities. Pollution Index (PI) method for water quality and Sediment Quality Guidelines (SQGs) method for sedimentation. The Krueng Woyla and Krueng Meuruebo watersheds include have the highest intensity of anthropogenic activity at West Aceh District. Surrounding the Krueng Woyla watershed has illegal mining such as class C minerals like sand and stone and gold mining. In the Krueng Meureubo watershed, there are mining activities to dispose of company waste flowing through the Meureubo tributary accompanied by sand mining activities. These activities result in the pollution index (PI) calculation. It shows that there has been a decrease in the water quality of the Meuruebo and Woyla rivers with 1.0 <PI< 5.0 classified as lightly polluted river water quality conditions. The highest pollution index value is in the Krueng Meruebo downstream watershed which is 2.41 classified as “Slightly Polluted”. Based on the Sediment Quality Guidelines (SQGs) and equations for a mercury concentration of 0.915, it is found that sediment has medium a negative effect index of heavy metals on river biota.

Taking in consideration that drinking water is a vital element without which the normal existence of humans and other living things in our planet cannot be thought of, we are motivated to research the wells and springs used for drinking in the villages of Bajgora, Kovacica and Kaqandoll. The suspicion that the waters of this mountain massif contain heavy metals due to the presence of mineral ores also prompted us to investigate the degree of presence or not of heavy metals in these waters. To assess the water quality of these wells, in the monitoring network that includes these three villages, we have pinpointed five monitoring points, determining the organoleptic, physic-chemical, and microbiological and heavy metal parameters. During the research process, in order to evaluate the water quality as accurately as possible, classical and instrumental methods of chemical analysis were applied. We have compared the results of the analysis with the standard values of AI16 / 2012- Administrative Instruction of Kosovo that has to do with the quality of water for human consumption and that is in full compliance with EU Directive 98/83 EC. The obtained results denote the presence with heavy metals of Pb, Zn, Cd and Ni, in four of the five samples taken for research. Therefore, we have come to the conclusion that the presence of these metals results as a consequence of the geological composition and ore-rich underground layers of this mountain massif.

The coastal zone of Losari Beach is located in a strategic position and rich in potential coastal resources, but the high density of human activities has decreased the quality of the surrounding waters.This study aimed to examine water quality based on meiofauna abundance and pollution index in the coastal zone of Losari Beach, Makassar. It employed a quantitative descriptive approach with purposive sampling method. The identified total meiofauna abundance was117,176 individuals/m2consisting of 138 species from 13 phyla. Ostracoda, olygochaeta, sarcomastigophora, ciliophora, and polychaetawere phyla with the highest abundance because of their high adaptability to polluted aquatic conditions. Meanwhile, tardigrada and aelosomatidaewere found in very low abundance because both phyla only thrive in pollution-free environments and have a pattern of high migration flow from one habitat to another. As for aelosomatidae, the habitat of its speciesis limitedto brackish or saline waters. A good-quality aquatic environment is a habitat for all benthic organisms and enables their even distribution. It explains the discovery of true and temporary meiofauna with uniform or even compositions in the bottom of the waters. The waters in the coastal zone of Losari Beach are heavily polluted. The stationslocated around the traditional Paotere harbor, hotels, restaurants, Losari Beach Platforms, the waste disposal outlets of Stella Maris Hospital, Fort Rotterdam canals, and Jeneberang River mouthhad very high pollution index. Some of these stations had low meiofauna abundance levels, and the poor water quality in their surroundings was caused by anthropogenic activity. Even though the area around TanjungMerdeka Beach had relatively low pollution index, it was categorized as severely contaminated because the index score was >10.

The Kura–Araks Basin is facing problems with insufficient water availability for all needs and poor water quality, which results in high rates of waterborne diseases. The riparians of the basin struggle with management of water resources within their national borders, as well as internationally, across the basin. With international rivers, interdependency among countries is created, where the upstream country can impact the quantity and quality of water downstream. This study focuses on the upstream–downstream relationship with the Kura River between Azerbaijan and Georgia. The analysis uses a game theoretical framework, which incorporates several issues in the negotiation space. Specifically, water quantity and water quality are analyzed separately and combined into an aggregated isolated game. The analysis compares the aggregated isolated game, where the outcome of each game is negotiated separately, with an interconnected game, where the two games are jointly negotiated. Using realistic parameters, results show that due to the repeated nature of some of the payoffs, cooperation is unlikely to be achievable in each game independently, since at least one country has an incentive to deviate. In contrast, the interconnected game can achieve full cooperation and increase the welfare of both countries.

In Guatemala 90 % of urban water has a rural origin and 70% of the sources are superficial. We selected three rivers of the upperbasin of Sis Icán (Chita, and Sacobá Ixconá-Sis; Pacific coast) to assesdrinking water. The watersheds have agriculture and livestock farms,as well as urban and rural populations. Water quality was assessed in the origin and end of each river, in 2012. The variables measured were:NO3, NO2 =, SO4 =, Fe, Cl, Mn, hardness, total coliforms and fecal coliforms.We applied the water pollution index, which is the average of the ratios between observed parameters and regulated standard values.We found statistically significant inputs for chemical and microbiological contaminants (total and fecal coliforms). The level of chemicalcontaminants does not compromise the quality of water for human consumption, but the biological contamination does.

Abstract The quality of Hindon River, western Uttar Pradesh, India was benchmarked with 19 sampling sites by analysing seventeen water quality parameters and eight heavy metals for pre and post-monsoon seasons to assess the existing quality of water which is a milestone for preparing roadmap for its betterment. Indices associated with water quality and heavy metals were computed to scale the accurate state of risk associated to its use for drinking and irrigation. During the pre and post-monsoon seasons, only four and five sites were found having safe water quality index (WQI) values respectively. The average WQI (2015–2019) for pre and post-monsoon seasons ranged between 8.69–706.47 and 7.20–341.56 respectively. During pre-monsoon and post-monsoon seasons w.r.t. drinking purpose, heavy metal pollution index ranged between 0.76–4470.78 and 0–1425.31 respectively; heavy metal evaluation index ranged between 0.21–163.11 and 0.00–57.70 respectively; contamination evaluation index ranged between -7.79–155.11 and –8.00 to 49.70 respectively. During pre-monsoon and post-monsoon seasons w.r.t. irrigation purpose, heavy metal pollution index ranged between 0.82–1492.71and 0.00–300.06 respectively; heavy metal evaluation index ranged between 0.10–20.44and 0.00–5.66 respectively; contamination evaluation index ranged between -15.97–10.03and –17.00 to –6.08 respectively. The heavy metals were positively correlated where highest value observed between Cu and Mn (correlation coefficient value 0.95). For physico-chemical parameters, observed adj-R2 value ranged from 0.50 for pH to 0.98 for total hardness and calcium. PCA analysis achieves three principle components (PCs) for physico-chemical and three PCs for heavy metals that explained 88.67% and 89.68% variability of the original data set, respectively.
