Water quality is closely linked to water use and to the state of economic development. Water pollution occurs when unwanted pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in water bodies and also to the natural biological communities. The present study is to assess the quality of river Khan at Triveni, Ujjain. Khan River flows from Indore via Sanwer it reaches Ujjain and joins Kshipra at Triveni. There are several industries in Indore, which throw their effluents in the river and it receives untreated sewage, drainage, run off from farms from the villages which are situated at the bank of this river. Though Bhangarh treatment plant has been setup at Indore to treat river Khan, only 30% of the river is being treated while rest of the water is untreated. Hence this source has been rendered unsafe for human consumption.

Critical Limit

One of the problems of functioning of coal industry enterprises is the formation of mine waters, which are discharged into water bodies and cause their dangerous pollution. The total volume of water pumped by the enterprise includes up to 15 % for the recycling cycle, the remaining 85% is discharged to surface water bodies. As a result, the ecological balance of coal regions is disturbed, their sanitary and hygienic state on the environment worsens, and the quality of coal is reduced due to the intake of polluted water for technological operations. The volume of mine water contamination increases during mining operations at deeper horizons and in difficult mining and hydrogeological conditions. In turn, this leads to pollution and depletion of underground aquifers and the formation of environmental risk factors. In Kuzbass, all these factors contribute to the development of water crisis, since the state of surface reservoirs has already reached a critical limit. Especially dangerous is the process of liquidation of mines. Closing mines and sections disrupt natural water flows, resulting in all water from the aquifers going to deeper horizons. More pollutants enter the water, which poison the underground hydrosphere of the regions. The paper analyzes the pollutants entering the underground and surface hydro grid at coal-fired plants and offers a Conceptual model for minimizing the risk of water pollution.

Untreated sewage has adversely affected the quality of marine recreational waters worldwide. Exposure to marine recreational water with poor microbial quality may pose a threat to bathers. The objectives of this study were to assess the effect of physicochemical parameters on Cryptosporidium and Giardia presence in marine recreational water of Sinaloa, Mexico, by Logistic Regression Analyses. Thirty-two 10-litre water samples were collected from two tourist beaches, Altata and Mazatlan, between November 2006 and May 2007. Water samples were processed by the EPA 1623 method and pH, temperature, salinity and turbidity were also determined. Cryptosporidium and Giardia were present in 71 and 57% of the samples collected from Altata, respectively. In Mazatlan, Cryptosporidium and Giardia were found in 83 and 72% of the samples, respectively. The overall concentration of Cryptosporidium ranged from 150 to 2,050 oocysts/10 L with an average of 581 oocysts/10 L and Giardia ranged from 10 to 300 cysts/10 L with an average of 73 cysts/10 L. The occurrence of both parasites increased in water with decreasing temperatures and increasing turbidity of the water.

The People

The development of an area must be accompanied by an ever-increasing population growth which will also increase the waste produced. Waste production will put pressure on the environment if it is not managed properly which will eventually end up in water bodies. The increased pollution load is also caused by the habit of people disposing of domestic waste, both liquid waste and solid waste directly into the water. Batujai Reservoir is one of the vital objects for the survival of the people of Central Lombok in particular, and the people of Lombok Island in general. Because of its vital role, the Batujai Reservoir needs to be saved so that the reservoir ecosystem can carry out its functions and benefits in improving the welfare of the people of Central Lombok. There are several community activities that are a source of direct reservoir water pollution (point source) such as fishing activities using floating net cages and disposal of domestic waste by the community which is directly channeled to water bodies. Pollutants collected in the Batujai Reservoir will reduce the water quality of the Batujai Reservoir. This research aims to analyze the water quality of the Batujai Reservoir which is caused by business activities and the community based on Government Regulation Number 82 of 2001 and to determine the water pollution index of the Batujai Reservoir. This study uses a quantitative approach by collecting primary data from direct observations in the field and secondary data based on previous research reports and government reports. The results showed that the average physical parameters were above the water quality standard threshold for class II water quality, the average chemical parameters were above the water quality standard for class III and class IV water quality, while the biological parameters were above the threshold. Water quality limits for class II and class III. The decline in water quality in the Batujai Reservoir is caused by various wastes entering the Batujai Reservoir water bodies. The analysis result with storet system shows that the water quality of Batujai Reservoir is in bad condition or heavily polluted.

The Impact

In recent years, sachet water known as "pure water" has gained the confidence of the Nigerien public because of its low price, availability, convenience, and quality perception by consumers. This study highlights the impact of storage on the quality of pure water sold in Niamey. Thus, eleven of the twelve analyzed physicochemical parameters have been monitored during six weeks of "pure water" storage in the sun and at laboratory ambient temperature. From the results obtained, the physicochemical parameters are in norms except the turbidity and the residual chlorine. On the Bacteriological plan, the total germs, the salmonellae, the fecal streptococci and the Escherichia coli have been identified. In addition, the monitoring of the evolution of the parameters analyzed during six weeks of storage revealed a change of the organoleptic quality that appears in the fourth week and a development of Escherichia Coli for the "pure water" exposed in the sun. This study showed, on the one hand, that these "pure water" would be unfit to the human consumption and on the other hand, their storage for a prolonged period and a high temperature affects their qualities. Les eaux conditionnées en sachet plastique, communément appelées "pure water", ont depuis quelques années, gagné la confiance du public nigérien en raison de leur faible prix, leur disponibilité, la commodité, et de la perception de qualité par les consommateurs. Ce travail étudie l’impact du stockage sur la qualité des "pure water" vendues à Niamey. Ainsi, onze parmi les douze paramètres physico-chimiques analysés ont été suivis pendant six semaines de stockage des "pure water" au soleil et à la température ambiante de laboratoire. A l’issue des résultats obtenus, les paramètres physico-chimiques sont dans les normes hormis la turbidité et le chlore résiduel. Sur le plan bactériologique, les germes totaux, les salmonelles, les streptocoques fécaux et les Escherichia colis ont été identifiés. Par ailleurs, le suivi de l’évolution des paramètres analysés pendant six semaines de stockage a révélé une altération de la qualité organoleptique qui se manifeste à la quatrième semaine et un développement des Escherichia colis pour les "pure water" exposées au soleil. Cette étude a montré, d’une part, que ces "pure water" seraient impropres à la consommation humaine et d’autre part, leur stockage pendant une période prolongée et une température élevée affecte leurs qualités.

The Assessment of seasonal changes in groundwater quality is an essential aspect for evaluating pollution level which can be a reflection of the source environment and the activities of man, including the use and management measures. This study examined the effect of seasonal variation on the physical, chemical, and biological properties of groundwater in the Bububu constituency which is located in the West district within the Urban –West region of Unguja Island. The study was conducted using cluster sampling.  Four clusters with a large number of wells were selected for further analysis. The number of wells from each cluster was sampled for physicochemical and bacteriological contamination levels. Samples were collected in two different seasons (Wet and Dry) to allow comparison between the two seasons. Analysis of water samples (N= 52) indicated that the sources are very vulnerable to microbial contamination particularly during the wet season at which 78.85% of the analyzed samples were contaminated with fecal coliform and unfit for human consumption. However, all measured physicochemical parameters were within the acceptable range except the levels of nitrate during the wet season in some samples taken at Kibweni and Sharifumsa which exceeded the recommended level by WHO. There is a need for adequate treatment of water particularly during the wet season as well as serious monitoring and proper regulation by the appropriate authorities to curb the menace and safe guard the lives of people to prevent a possible epidemic.

Introduction: Land use change and waste discharge from coffee processing may be affecting quantity and quality of water supplying urban areas in the coastal region of Oaxaca.Objective: To determine the level of contamination of aquifers and estimate surface water runoff in micro-watersheds of Pluma Hidalgo and Santa María Huatulco in Oaxaca, Mexico.Materials and methods: Seven water supply points were analyzed during the rainy season of 2019. The following physicochemical parameters were determined: pH, total dissolved solids, electrical conductivity, hardness, total solids, chlorides, and chemical oxygen demand (COD). Surface runoff was estimated using the Raws and Prevert methods.Results and discussion. Water bodies are within the permissible limits for human use. The Chacalapilla spring was classified as moderately hard (85 mg CaCO3∙L-1), while the seven water bodies exceeded the permissible limit for COD (40 to 200 mg∙L-1); therefore, water is in a contaminated classification range and is not suitable for human consumption. Surface runoff values suggest a medium conservation condition of vegetation cover; areas with higher cover recorded lower runoff coefficients.Conclusions. The physicochemical parameters indicated that water from Pluma Hidalgo and Santa María Huatulco is suitable for human use, but not for drinking

According to the latest SDG recommendations, guidelines on access to safe drinking water have enabled the construction of boreholes in remote areas of developing countries. In Togo,  particularly in the savannah region where access to drinking water remains a major problem for the population, many boreholes have been built for this purpose. The objective of this study is to evaluate the bacteriological quality of the waters of some boreholes built in four (04) prefectures of the savannah region in Togo. A total of 68 samples of drilling water intended for human consumption were collected between January and February 2019 for bacteriological analysis.  These analyses were  carried out according to the standardized routine methods of the French Association for Standardization (AFNOR). The parameters sought or counted in these  samples are those retained by  the 2007 European Union criteria for water intended for human consumption. The analysis reveal that the samples of borehole water are at 50% and 90%   of unsatisfactory hygienic quality respectively compared to the Total Coliforms (CT) and the Total Aerobic Mesophilic Flora (FAMT) which are indicative germs of hygiene failure. The correlation of the germs sought made it possible to distinguish two groups of indicators of contamination: those  responsible for  hygiene  failures and old fecal contamination (ASR) Conclusion: Since the majority of the borehole water analyzed is contaminated by germs indicating  hygiene deficiencies, adequate  treatment of these waters and monitoring of their quality  are necessary in order to protect the population of the savannah region against probable diseases linked to faecal contamination germs.
