Sustainable Water Supply

Bolivia is among the countries with the highest availability of freshwater globally. However, many of its natural sources are impacted by anthropogenic activities, such as mining. Water is intimately linked to public health and is essential to achieving sustainable development. It is necessary to preserve water resources by designing and validating monitoring programs that help control the quality of the sources that supply important population centers. The study area in this research is the upper part of the Milluni micro-basin, whose lagoon system supplies water for two large cities. Milluni is close to illegal and abandoned mining areas, making the region highly vulnerable to heavy metal contamination. This study aimed to optimize the resources available for monitoring Milluni. The frequency of monitoring was statistically determined, and the correlation between parameters measured in situ (pH and conductivity) and metal ion concentrations to determine low-cost indicators to monitor the presence of heavy metals. A multivariate analysis of friction of the results of the pilot year of the monitoring program designed for Milluni, considering the characteristics and economic limitations, is presented. An approximation of the quality of the surface water resources of Milluni is presented as a result of the monitoring operations.

The water resources in Rajasthan State are facing a crucial stage even after average/good rainfall. Temporal distributions as well as the spatial variability of rainfall within the state were investigated by applying an analysis of variance (ANOVA) test. The effect of change in catchment characteristics and anthropogenic activities on overland flow are also investigated in this paper by applying a regression technique. Inflow to the surface water resources of the state is regularly decreasing. Time series analysis and sequential cluster analysis reveals that 1994 was the critical year, which divides the two consecutive non-overlapping epochs viz. pre-disturbance and post-disturbance. Due to increasing population and the subsequent increase in agriculture (specifically using groundwater sources) having increased catchment interceptions, there is a regular decreasing trend of surface runoff and surface water availability. The study highlights that, in spite of an increasing trend of rainfall witnessed during the last 100 years, inflow to the surface water resources of the state is decreasing at a fast pace owing to a decrease in the percentage area contributing to surface runoff.

Abstract The oasis of Moghrar is located in the wilaya (province) of Naama, in the southwest of Algeria. It is well known for its Ksours, its palm groves and the good quality of its fruit and vegetables, especially the dates and their varieties. This region contains important groundwater and surface water resources. For several centuries, domestic water supply and irrigation have been carried out using traditional techniques of water harvesting such as pendulum wells and foggaras. Currently, this hydraulic heritage is meeting technical and social problems, particularly with the contribution of drilling and motor-pumps. The main issues are water table drawdown, the drying-up of water sources and degradation and decay of traditional techniques. The objective of this study is to make an inventory of all water sources in the study area, to study the impact of the contribution of modern techniques on ancestral techniques and finally to propose recommendations for safeguarding the hydraulic heritage.

Due to industrialization and over population, surface water resources are out of reach from many people so consumption of ground water is the only choice to overcome the water scarcity. Naturally, ground water is one of the significant and potable water resource but some geographical conditions and anthropogenic activities deteriorate the water quality and make it objectionable for drinking. This study was conducted to evaluate the ground water quality of Karachi, Pakistan. For this, 42 ground water samples were collected from different districts of Karachi and analyzed their physicochemical and microbiological characteristics and compared with both international (WHO) and national (SEQS) drinking water standards. Observations of the study declared that overall contamination (physicochemical and microbial) in the ground water samples of different districts of Karachi was as follow West (21%), South (20%), Central (17%), Malir (16%), Korangi (14%) and East (12%). Physical assessment of the study area declared that pH and turbidity of the ground water samples varies in the range of (6.54-7.9) and (0-1.01 NTU) which exist in the standard prescribed limit. Whereas, detection of chemical contaminants particularly TDS (457-12090 mg/L), hardness (118.8-3645 mg/L) and chloride (190-4918 mg/L) content in most of the samples were also exceed from the prescribed limit. Additionally, arsenic was abundantly present ranging from 3.52-13.63 mg/L in all collected samples of Karachi city while the concentration of cadmium (range: 0.0005-0.5012 mg/L) and lead (range: 0.201-1.817 mg/L) were also high in few samples, from the permissible limit of drinking water. Microbial contamination was also detected in which coliforms were present in the range of 0-150 CFU/100mL, which also unfit the water quality. This deteriorated ground water quality of Karachi can be improved by maintenance of proper sanitary conditions of the communities and implementation of water treatments, otherwise consumption of such water may develop serious health related consequences in the consumers.

Climatic changes influence on surface water resources directly and in that way, more or less, more quickly or more slowly, by means of waterfalls, the quantity and quality of ground waters or hydrogeological resources, namely their sustenation. The conclusion about the influence of climatic changes on ground waters can be drawn on the basis of isotope research (2H, 14C) by means of which their origin and age are determined most reliably. Present investigation results of the origin and age of ground water resources at the most famous hydrogeothermal regions, as well as the sustenance forecast of their quality and reserves depending on still existing and future climatic changes will be shown in this paper.
