Water is one of the vital needs of all living beings for daily activities like drinking, washing, bathing etc. It is the most important factor in shaping the land and regulating the climate. The quality of water for drinking and other activities if does not satisfy the standard conditions of physical, chemical and biological characteristics as prescribed it then becomes ineffective. The quality of water is usually described according to its. Hence it becomes necessary to find the suitability of water for various purposes like drinking, irrigation and Industrial purposes. Rapid industrialization and use of chemical fertilizers and pesticides in agricultural lands, discharge of voluminous municipal and industrial waste waters are causing deterioration of water quality vis-à-vis depleting of aquatic biota. This ultimately causes massive pollution not only to the rivers, ponds and wells but also drastically degrade the quality of groundwater. Research have been undertaken to use such type of waste water in different construction purposes. It is absolutely true that demand of fresh water by the construction sector is expected to increase due to high increase in the growth of construction activities in India (Dhanraj, 2017). Highly polluted Sutlej river in Punjab has been a constant encouragement to the environmentalists about reusing the contaminated water of the river. A total of 14 water samples from different point sources of pollution were collected and tested for physico-chemical parameters (pH, temperature, DO, BOD, COD, TSS, TDS), metals (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) and microbiological parameter using World Health Organization (WHO) and the Bureau of Indian Standards (BIS) standards to justify how the strength of concrete goes on varying with respect to using the river water directly. An attempt was made to justify the use of wastewater directly in preparing concrete for construction purposes by testing concrete cubes prepared by the untreated water and comparing them with the strength of standard cubes.

Nitrate groundwater contamination is of major interest all over the world. This problem arises in agricultural regions across Morocco. An excess amount of nitrate causes a serious problem in urban water networks and human health. Because of these health risks, considerable attention has been paid to find effective treatment processes to reduce nitrate concentrations to safe levels. The World Health Organization has set an acceptable level for nitrate in drinking water at 50 mg/L. The aim of this study is to reduce the nitrate concentration from groundwater using two membrane processes: Electrodialysis (ED) and Nanofiltration (NF). Efficiencies of these two technologies are compared in respect to nitrate ions removal, cost process and final quality of water. The results of technologies show that, for electrodialysis standards level can be achieved for a demineralization rate of 15% and the physico-chemical quality of the produced water is satisfactory. For nanofiltration we obtain a nitrate removal of 90% but the produced water is very de-mineralized and must be remineralized.

This study was done to determine the quality of water from hand-dug wells in Kuje, Federal Capital Territory Abuja Nigeria. The study area lies between latitudes 080 53’ 24’’N and 080 53’ 47’’N and longitude 070 14’ 24’’E and 070 14’ 35’’E. Water from twenty wells were randomly sampled. The physical properties investigated are pH, temperature, total dissolved solid (TDS) and electrical conductivity. The chemical analysis involved determination of the concentration of anions (SO42-, HCO3-, Fl-, CO3-, Cl-, NO3) and cations (Ca2+, Mg+, Na+,K+, Zn+, Fe2+, Cu2+. A piper diagram based on the relative percentages of the ions was plotted for classification according to hydrogeochemical facies of each water sample based on their dominant ions. The Piper diagram indicated Ca2+ and HCO3- as the dominant ions and therefore it is Ca−HCO3 water type. The physical properties of the water were found to be good based on World Health Organization (WHO) guidelines and National Drinking Water Quality Standard (NDWQS) and therefore water in the study area is safe for human consumption.KEYWORDS: groundwater, hydrochemical facies, anion, cation, piper diagram

The results of the study of ecological and geochemical features and assessment of the water quality of water sources located on the territory of the Semipalatinsk test site are presented. The studied waters are diverse in chemical composition: 14 % of the samples had hydrocarbonate, 69 % – sulfate, and 17 % – chloride types of waters. On the basis of the revealed features of the elemental composition of the underground waters of the Semipalatinsk test site, decreasing series of excess of the average concentrations of elements in water in relation to the composition of waters of the zones of hypergenesis and continental salinization were constructed: U14 > Mo8 > Sr8 > V3 (hypergenesis zone), U5 > Mo3 > Sr3 > V2 (zone of continental salinization). For the groundwater of the Semipalatinsk test site, specific elements were identified, such as U, Mo, Sr and V. The water quality was assessed for the studied chemical components based on comparison with the standards of the Republic of Kazakhstan and the World Health Organization (SaNPiN No. 209, WHO 2011).

The key to provide microbiologically safe drinking-water lies in understanding the various mechanisms by which water gets contaminated. This study assessed the risk of contamination and microbiological and chemical quality of water from protected dug wells in five selected Panchayats in Kollam district, Kerala state, southern India. Sanitary inspection was conducted for 70 protected dug wells using World Health Organization established procedures for risk of contamination scoring. Microbiological and chemical analysis of water samples was done. The areas with higher incidence of hepatitis A had a higher proportion of wells with high risk of contamination scores (p = 0.006). High risk of contamination scores for wells were associated with higher incidence of fecal pollution (odds ratio 11.80; 95% confidence interval 1.87–74.86). The study highlighted the need to make the wells safe in this area, for control of waterborne diseases.

The Impact

Water is a vital element for the development and maintenance of life on our planet, for which it is necessary to preserve and ensure the continual persistence of water, not only to provide man with a sufficient quantity for these needs but to assure him an ir upright quality of this water. The main objective of this work is to evaluate the physicochemical quality of the water of the Temara water and the comparison of this quality with Moroccan and international standards. Physico-chemical analyzes showed true variations in the different parameters studied, related to the impact of agricultural activities. The physicochemical characterization of the samples revealed a pH close to neutrality and relatively high salt contents. The chloride content was between 14.20 and 958.5 mg / l. For nitrate and nitrite load varies and 0.5 mg/L and 5.7 mg / L. These parameters of pollution were relatively high , compared to the average concentrations usually met for Moroccan drinking .The results obtained clearly exceed the standards of WHO (World Health Organization). Effluents therefore constitute a health risk. In conclusion, the pretreatment of these waters is strongly recommended.

Abstract An assessment of consumer quality perception, as well as some physical and chemical characteristics of water samples sourced from wells, boreholes, and rivers in the locality of Pelengana commune, in Mali, was carried out. The World Health Organization (WHO) Guideline (or other) Values (GVs) for drinking water quality was used as a benchmark. One-way analysis of variance (ANOVA) alongside Duncan's multiple comparison tests for significant differences, and Principal Component Analysis (PCA) were used in analyzing differences and correlations regarding the parameters investigated. Results revealed that the majority of the households (61.2%) regarded wells and river water as unsafe for drinking. The physical and chemical quality of water was affected by climatic season. Also, with the exception of iron (average values), the parameters studied met the WHO GVs. Based on the analyzed parameters, the quality of these different water sources is chemically acceptable.

Abstract This study investigated the quality of water in the Gomal Zam Dam and its tributaries, south Waziristan District, Pakistan. For this purpose, water samples were collected from the Gomal Zam Dam and its tributaries in the winter and summer seasons (n=24 in each season). Water samples were analyzed for the anions using a multi-parameter analyzer (CONSORT 6030, Belgium) and cations by the Atomic Absorption Spectrophotometer (AAS, AAnalyst 700, PerkinElmer). Water characteristics were compared and found within drinking water guidelines set by the world health organization (WHO), except turbidity. Water characteristics were evaluated for the water quality index (WQI) and sodium hazards such as sodium adsorption ratio (SAR) and sodium percentage (Na%). Based on WQI and sodium hazards, the water of Gomal Zam Dam and its tributaries were observed as good and in permissible levels for drinking and irrigation water, respectively. The winter season has slightly poor water quality compared to the summer season due to higher contamination. Gibbs’s and Piper's models showed that the water quality of Gomal Zam Dam and its tributaries was mainly characterized by the weathering of bedrocks. The studied water is classified as Na-Cl type and Mg-HCO3 types in the summer and winter seasons, respectively. Statistical analyses revealed that geogenic sources of rock weathering are the dominant factor for controlling the water quality of the area.

QUALIDADE DA ÁGUA UTILIZADA PARA IRRIGAÇÃO DE HORTALIÇAS NA REGIÃO DE BOTUCATU-SP  Ana Maria Morato Fávero de Fravet; Raimundo Leite CruzDepartamento de Engenharia Rural, Faculdade de Ciências Agronômicas, Universidade Estadual Paulista, Botucatu, SP, [email protected]  1 RESUMO Objetivou-se com o presente trabalho verificar a qualidade da água utilizada para irrigação por produtores de hortaliças da região de Botucatu-SP.Foram entrevistados 27 produtores que vendem hortaliças nas feiras livres de Botucatu. Dentre estes produtores, foram selecionados dez, sendo um de cada localidade.Foram coletadas três amostras de água de cada fonte. Os principais padrões para avaliar os resultados obtidos foram os da Resolução do CONAMA (Conselho Nacional do Meio Ambiente) N° 357, de 17 de março de 2005, que estabelece os padrões para classificação dos corpos de água.A Condutividade Elétrica foi avaliada segundo valor sugerido pela CETESB e a cor foi verificada conforme a OMS (Organização Mundial da Saúde), para água potável devido a Resolução do CONAMA não estipular um valor para classificação.Para a saúde pública, apenas os coliformes e o nitrato são as variáveis preocupantes por estarem relacionados com a incidência de doenças, assim, das águas analisadas, 40% delas (produtores A, F, H e J) oferecem algum tipo de risco para a saúde da população de Botucatu, segundo padrão estabelecido pelo CONAMA.Podemos concluir que, de maneira geral, essas águas, encontram-se em condições não alarmantes, pois não apresentam valores muito diferentes daqueles estabelecidos pela legislação. UNITERMOS: classificação dos corpos de água, saúde pública, coliformes, nitrato.   FRAVET, A, M. M. F. de; CRUZ R. L. QUALITY OF WATER USED FOR VEGETABLE IRRIGATION IN BOTUCATU AREA  2 ABSTRACT This study aimed to verify the quality of water used for irrigation by vegetable farmers in Botucatu area.27 farmers that sell vegetables in the street markets of Botucatu were interviewed. Among them, ten were selected. Each one was from a different place of the studied area.Three water samples from each water source were collected. In order to evaluate the obtained results, the main used standard was the one used by CONAMA (National Environment Council) resolution No. 357, March 17, 2005, because it establishes the standard for water classification.The Electric conductivity was evaluated according to values suggested by CETESB, but water color was verified according to WHO (World health organization) standard for drinking water because the CONAMA resolution does not determine classification values for that.For public health, just coliforms and nitrate are the preoccupying variables because they are related to the incidence of diseases. 40% of analyzed waters (A, F, H and J farmers) offer some risk to Botucatu population’s health, according to the standard established by CONAMA.We can conclude that in general analyzed waters are in non-alarming conditions and do not present very different values from those established by the legislation. KEYWORDS: water classification, public health, coliforms, nitrate.
