Contaminated Drinking Water

People on Earth are under tremendous threat due to undesired changes in the physical, chemical and biological characteristics of water and soil. Due to increased human population, industrialization, use of unwanted amounts of fertilizers and man-made activities, water and soil is highly polluted with different harmful contaminants. Natural water and soil contaminates due to weathering of rocks and leaching of soils, mining processing etc. It is necessary that the quality of drinking water and soil should be checked at regular time interval, because due to use of contaminated drinking water, human population suffers from variety of water borne diseases. The study area, Gossaigaon sub-division of Kokrajhar district, Assam lies on the north bank of the Brahmaputra river and is slowly sloping towards south from the foothills of Bhutan upto an average height of 42 MSL. The tributaries of the Brahmaputra- Sankosh, Ripu, Dambra, Bura chara, Gadadhar, Gurufella, Madati, Hel, Gongea are flowing southward which have their sources in the Himalayas. In this paper an attempt has been made to assess the quality of soil of 10 different stations by considering the parameters like Colour, Temperature, pH value, Conductance, Alkalinity, Dissolved Oxygen, Hardness, TS, TDS, Chlorine, Fluorine, Sulphur, Nitrogen, Phosphorous, Iron, Calcium and Magnesium, Sodium, Potassium, Zinc, Nickel, Lead and Copper which have direct correlation with human health.

Three ultrafiltration membranes were prepared using phase separation techniques. The membranes were characterized by scan electron microscope, porosity, pore size distribution measurement, and mechanical properties. The membrane performance was carried out using synthetic solutions from humic acid and tap water to express the contaminated drinking water. The polyvinylidene difluoride (M2) has the highest tensile strength 33.2 MPa with elongation of 52.3%, while polyacrylonitrile (M3) has the lowest mechanical properties, tensile strength 16.4 MPa with elongation of 42.7%. Polyethersulfone membrane (M1) provides the highest removal of humic acid, which was 99.5, 98.8, and 98.2% using feed concentrations 0.1, 0.3, and 0.5 g/l, respectively, while M3 provides the highest permeate flux which was 250, 234.4, and 201.4 l/m2 h using feed concentrations 0.1, 0.3, and 0.5 g/l, respectively. Analysis of water samples indicates that the prepared membranes can be used to treat the contaminated drinking water which produced the high quality of drinking water after treatment.

Purpose. Assess the quality of drinking water of sources of decentralized water supply of rural settlements of Berezivka united territorial community of the enlarged Zhytomyr district. Methods. Field, laboratory-analytical, statistical. Results. As a result of research it is established that the greatest contribution to the pollution of drinking water is made by nitrates, the excess content of which was recorded on average in 50.7% of the selected samples, and in 57% of the studied settlements water belongs to quality class 4, "Limited" given undesirable quality. A critical situation was recorded in Bolyarka, Bondartsi, Dubovets and Cheremoshne villages, in which well water had increased content of nitrates in all selected samples. On average, 34% of the selected water samples do not meet the standard for the pH value in the direction of its reduction. In terms of pH, quality classes vary from "excellent", very clean to "good", clean water with a bias to the class of "satisfactory", slightly contaminated acceptable quality). The total iron content exceeded the standard by 6.6% of the selected samples. Conclusion. It is proved that the formation of the general class of water quality is significantly influenced by a group of general sanitary indicators, which is primarily due to the high content of nitrates in the studied sources of decentralized water supply. The calculation of the integrated ecological index of development of rural settlements according to the indicators of drinking water quality showed that such rural settlements as: Zamozhne and Sadky need priority attention; 11 settlements need improvement; only village of Vasylivka needs support at the same level.

Environmental contamination is still a pressing issue, in particular, contaminated drinking water sources and contaminated drinking water from centralized communal water supply systems, since it produces negative effects on human health. Our research goal was to estimate probable impacts exerted on overall morbidity in Samara by quality of drinking water taken from centralized communal water supply systems as a most significant environmental factor. Our research tasks included taking and analyzing drinking water samples from centralized communal water supply systems; calculating carcinogenic and non-carcinogenic health risks caused by analyzed chemicals. To fulfill the tasks and achieve the goals, in 2018–2019 we performed sanitary-chemical analysis of drinking water quality as per 20 sanitary-chemical parameters; our research object was drinking water taken from centralized communal water supply systems in 7 districts in Samara. Obtained actual data on contamination of water taken from centralized water supply networks in Samara were used as primary basis for calculating hazard indexes and carcinogenic risk coefficients using conventional exposure scenarios. In our research we revealed that maximum total non-carcinogenic hazard quotient was determined by arsenic and petroleum products introduction. Assessment of carcinogenic risks caused by contaminants in drinking water revealed that total health risk for children younger than 18 was within the second range as per its median; total carcinogenic risks for adults, within the third range. At the same time, arsenic contents did not exceed hygienic standards in all examined samples. So, we assessed carcinogenic and non-carcinogenic risks, basing on actual data on quality of drinking water taken from centralized communal water supply systems. It seems vital to perform a wider-scale controlled study in several regions in order to assess significance of revealed factors for morbidity among population.

Large dams play an important role in promoting economic and social development in many countries. However, the construction of such dams can have a detrimental effect on the environment. The aim of this study was to investigate perceptions of drinking water quality among inhabitants of selected communities within the Bui Dam environs. With the help of questionnaires, 100 respondents from communities “near to the dam” were randomly selected and interviewed. Their responses were compared with another 100 respondents selected from “far from the dam” communities. These were augmented with in-depth interviews, focus group discussion, and personal observation. Analysis of the results showed that, there were greater proportions (31%) of the participants who lived in “near communities” within the age category 20–25 compared to 19% of their “far communities” counterparts. There were significantly greater proportions of female respondents in the “near to the dam” (57%) compared to respondents in the “far from the dam” communities (52%). The study further showed that the perception of risk of consuming contaminated drinking water was more common among “far from the dam” communities (odds ratio = 4.57). The perception of the quality of water based on some physical properties was investigated as part of our study. Analysis of the results showed that significantly greater proportion of the “far from the dam” communities (35%) perceived their water had an objectionable smell compared to 7% of inhabitants of their other counterparts (p value = 0.001). The study further showed that significantly greater proportion of the study participants in the far from the communities perceived that their water had colour (65%) and they did not drink water from any other source (63%) apart from their stream. The study demonstrated that generally, inhabitants within the study communities perceived the construction of the Bui Power Project has negatively affected their drinking water quality.

The Impact

Проблема загрязнения питьевых вод является очень актуальной для урбанизированных территорий планеты. Подземные воды Северо-Осетинского артезианского бассейна сегодня являются одним из основных источников, обеспечивающих население Республики пресной водой. Вместе с тем подземные воды бассейна уязвимы, мало защищены от техногенного воздействия. Наличие на территории РСО-Алания предприятий горнопромышленного, металлургического и др. производств негативно сказывается на качестве подземных вод. В статье рассматривается его современное состояние. Цель работы – изучение техногенного воздействия на подземные воды, использование подземных вод Северо-Осетинского артезианского бассейна, его гидрогеохимические показатели. Методы исследования. Гидрологические и гидрохимические исследования водоносного копмлекса, проведенные за последние десятилетия в гидрогеологических скважинах, которые были пробурены с целью водоснабжения населения и промышленных предприятий столицы республики, показывают, что качество подземных вод соответствует требованиям, предъявляемым к питьевой воде. Результаты работ. Изменение качества артезианских вод бассейна происходит под влиянием интенсивности их добычи, как непосредственно из бассейна, так и в зоне питания водоносного комплекса. На Редантском месторождении отмечается понижение уровня воды эксплуатируемого водоносного горизонта, а также засорение скважин. Расположение Орджоникидзевского месторождения (выше Редантского) способствует низкому уровню выхода сульфидных вод на поверхность.Высокая интенсивность эксплуатации Орджоникидзевского месторождения приводит к понижению уровня вод в продуктивном водоносном горизонте, который приводит к смешению минеральных вод с водами, в которых имеется высокое содержание солей, от чего меняется ионный состав подземных вод, их оттоку в сторону формирования водоносного комплекса отложений рухсдзуар Северо-Осетинского артезианского бассейна. Также большое влияние на формирование химического состава вод оказывает бессистемная эксплуатация водоносного горизонта в северо-восточной части Владикавказа The problem of drinking water is very vulnerable to the urban areas of the planet. Groundwater of the North Ossetian artesian basin today is one of the main sources providing the population of the Republic with fresh water. At the same time, the underground waters of the basin are vulnerable, poorly protected from anthropogenic impact. The presence on the territory of North Ossetia-Alania of mining, metallurgical, and other enterprises negatively affects the quality of groundwater. The article discusses its current state. The aim of the work is to study the impact of the ground water use in the North Ossetian artesian basin and its hydrogeochemical parameters. Methods. Hydrological and hydrochemical studies conducted in recent years in hydrogeological wells, which were drilled to supply the population and industrial enterprises of the capital in republic show that the quality of groundwater meets the requirements for drinking water. Results. The change in the quality of artesian waters of the basin occurs under the influence of the intensity of their extraction, both directly from the basin and in the recharge zone of the aquifer. At the Redant field, a decrease in the level of exploited aquifer is noted. The location of the Ordzhonikidze field (above Redant) contributes to a low level of sulfide water output on the surface. The high intensity of exploitation leads to a decrease in the water level in the productive aquifer, which leads to a mixed content of mineral waters and water in which there is a salt content, which changes the ionic composition of groundwater, and their outflow towards the formation of rukhsdzuar aquifer complexes of the Ossetian artesian basin. Great influence on the chemical composition of water has a patternless exploitation of the aquifer in the north-eastern part of Vladikavkaz
