“…The total value of the indicator in the first measurement series was 99.67. The WQI result (close to 100) obtained for the Zimny Sztok source from the first measurement series can be compared with WQI values from the area of typical waste landfills [48]. In the case of drinking water sources, the values of this indicator should be in the range of 0-25 [49,50].…”

Enabling citizens to have access to good-quality water is an important challenge in the 21st century. Water quality in springs located in urban areas may deteriorate as a result of natural and anthropogenic factors. The quality of water in springs is influenced not only by rock weathering, evapotranspiration and climate change but also by the lack of sustainable resource use. Anthropogenic activities, including industrial and domestic and agricultural activities, may not only lead to an increase in pollutants such as nitrates, chlorides and heavy metals but also to the development of dangerous bacteria. Research on water quality was conducted in two series of measurements at the Zimny Sztok spring (southern Poland), located in an urban space. The results of the analyses indicate that the waters of this spring, despite anthropogenic pressure, exceeded the permissible values for drinking water only in terms of the total number of microorganisms. Unfortunately, this was not confirmed by Water Quality Index (WQI) values. These were approximately equal to 99 in the first measurement series and about 41 in the second series. Maintaining appropriate water quality is one of the goals of rational water management, and the constant control of selected parameters in the water falls within the scope of the concept of smart city/smart water. The example of this spring shows that the water was used by residents without information about its current physicochemical parameters and bacteriological composition. This problem can be solved in the future by implementing a monitoring system for this point. The aim of this work was to examine the quality of water in the spring, use the WQI to determine the potential risks and present the general problem of people consuming water from urban sources without knowing about their parameters.

Correctly assessing the impact of waste landfills on groundwater quality requires the development and use of comprehensive tools that consider the content of individual components in water, as well as those relating to the hydrochemical background. The article presents a comparative analysis of selected water quality indices used around the world to assess the environmental threat caused by sources of pollution. The paper includes the following indicators: Water Quality Index, Landfill Water Pollution Index, Nemerow Pollution Index, Backman Index, Canadian Water Quality Index, Horizontal Ratio, Enrichment Factor and Fuzzy Water Quality. Attention was paid to the values of individual indices, their applicability in municipal and industrial waste landfills, and limitations in their use. A literature review has proven that some indices, such as the Landfill Water Pollution Index and Nemerow Pollution Index, are used very often as they provide reliable results. Index methods help conduct rational water management, complement groundwater quality monitoring, and serve as a tool for making decisions in various water protection areas.

Groundwater resource plays a central role in every sector of life globally. Unfortunately, the roles of groundwater are often unappreciated in many parts of the world, especially in developing nations. The paper applied a combined geo-electrical method and hydrochemical analysis alongside physical surveys to investigate aquifer promising zones, the quality and the source of water supply in the selected regions. The geo-electric resistivity data were used to select the most aquifer-promising zone for groundwater development with a key interest in groundwater potential and aquifer overburden protective capacity overlying the water-bearing unit. Seventeen (17) vertical electrical sounding (VES) acquired in four regions reveals that the regional weathered/fractured unit which constitutes the aquifer unity extends from 13.4 m to 41.3 m in depth with the subsurface resistivity value varying between 53 Ωm–1013 Ωm in terms of resistivity values. The overburdened thickness (protective soil layers) stretches from 2.5 m to 13 m with a resistive layer of resistivity values ranging from 111 Ωm to 2877 Ωm, which could provide high aquifer protective cover for the regional groundwater systems. The computed aquifer transmissivity and hydraulic conductivity range from 0.54 $${m}^{2}/h$$ m 2 / h –15.85 $${m}^{2}/h$$ m 2 / h , and 0.95 m/day–9.19 m/day, respectively. The estimated average longitudinal conductance (0.2 moh) reveals that the regional groundwater systems are moderately protective against surface contaminants. In addition, the physicochemical water analysis was examined, which exposes the level of heavy metals (HMs) compositions in the regional groundwater systems and the possible public health risks compared to WHO permissible drinking water limits. The sample water from the Rivers had the highest concentration of HMs (0.089 mg/I–2.012 mg/l), followed by the hand-dug wells (HWDs) (0.033 mg/l–1.555 mg/l) and the lowest in the borehole (0.011 mg/l–0.511 mg/l). In contrast, the borehole water sample shows a moderation where the HMs presence falls within the WHO standard for drinking water. The outcomes of the study show that 63% of the investigated region consumed water with a high concentration of HMs above the WHO permissible standard allowance for drinking water, while only 37% took water that falls within the WHO permissible standard. In conclusion, the study showed significant impacts of anthropogenic activities on the regional water quality, which provides vital information about the regional groundwater systems and the quality of water supply for adequate groundwater development and sustainability.
