Drinkable Water

AbstractWater pollution is one of the most dangerous problems which is commonly ignored in our country. Pakistan ranks very low in the world, regarding drinkable water. Both surface and underground water are contaminated with toxic metals and pesticides and arsenic (μg/L) were found to be 50. The quality parameters set by the WHO are persistently violated. The water quality is seriously affected by improper disposal of industrial, domestic waste and agrochemicals. These pollutants are responsible alone, or along with other factors for a variety of health problems. This article discusses drinking water being supplied in Sahiwal (Pakistan) to students living in the hostel along with an emphasis on the major pollutants, their effects and consequent health problems. The data presented in this article have been collected in Sahiwal. The water samples were collected from the main supply and the blood samples were of the consumers of that water.

Water pollution is one of the significant dangers to general wellbeing in Bangladesh. Drinking water quality is inadequately overseen and checked. Bangladesh positions at number 86 among 142 countries with respect to drinking water quality. Drinking water sources, both surface and groundwater are debased with coliforms, harmful metals and pesticides all through the nation. Different drinking water quality parameters set by WHO are every now and again damaged. Human exercises like uncalled for transfer of civil and mechanical effluents and aimless utilizations of agrochemicals in agribusiness are the principle factors adding to the crumbling of water quality. Microbial and substance contaminations are the primary elements mindful solely or in mix for different general medical issues. This paper presents a detailed layout of water quality in Bangladesh with unique accentuation on significant poisons, sources and causes of pollution. The information introduced in this paper are extracted from different surveys and reports distributed in national and global journals. Likewise reports discharged by the government and NGO associations are incorporated.BIBECHANA 15 (2018) 97-112

A total of 111 water samples were drawn from 15 wells. These samples were subjected to bacteriological examinations to determine the suitability of the monitored wells as source for drinking water. Significant levels of bacterial pollution indicators were detected in the underground water samples during the period of study. Total bacterial counts ranged between 10-104CFU/ml. Faecal streptococci was the most common and detected in 9 6% of water samples. Lower percentages of samples (92, 55 and 45%) were contaminated with total coliforms, faecal coliforms and total clostridia, respectively. Faecal coliforms: faecal streptococci was less than 0.7 in 86% of the examined samples. Anaerobic bacteria were detected in the examined well water samples. Only 101 water samples were tested for anaerobic spore-formers and all showed positive results. Most examined wells do not meet the water quality standards for drinking water. Accordingly, the necessity of controllin bacterial pollution in ground-water through disinfection was clearly confirmed. Testing the underground water for more than one indicator represents an important approach for water quality assurance.

AbstractThis study aimed to determine the quality of drinking water supplied in different types of food stalls in Jashore Municipality, Bangladesh. A total of 35 water samples were collected from different tea stalls, street side fast food stalls, normal restaurants and well-furnished restaurants. The water quality was evaluated by determining the distinct physical, chemical and biological parameters. The results revealed that the water used in the food stalls and restaurants for drinking purpose was in desired quality in terms of turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), sulfate (SO42−), phosphate (PO43−), chloride (Cl−), sodium (Na) and potassium (K) concentrations. The values were within the permissible limit proposed by the Bangladesh Bureau of Statistics and the World Health Organization. Concentrations of calcium (Ca) and magnesium (Mg) found in several samples were higher than the World Health Organization standard. Iron (Fe) concentrations were higher than the permissible limit of the World Health Organization. Only 46% exceeded the permissible limit of Bangladesh Bureau Statistics. The threatening result was that the samples were contaminated by fecal coliform, indicating that the people of Jashore Municipality may have a greater chance of being affected by pathogenic bacteria. The drinking water provided in the street side fast food stalls was biologically contaminated. The findings demonstrate that the drinking water used in food stalls and restaurants of Jashore Municipality did not meet up the potable drinking water quality standards and therefore was detrimental to public health.

<p>Forested watersheds are critical sources of the majority of the world’s drinking water. Almost one-third of the world’s largest cities and two-thirds of cities in the United States (US) rely on forested watersheds for their water supply. These forested regions are vulnerable to the increasing incidence of large and severe wildfires due to increases in regional temperatures and greater accumulation of fuels. When wildfires occur, increases in suspended sediment and organic carbon can negatively affect aquatic ecosystem health and create many costly challenges to the drinking water treatment process. These effects are often largest in the first year following a wildfire. While past research has shown the likelihood of source water impacts from wildfire, the magnitude of effects remains uncertain in most regions. In our study, we will quantify the projected short-term effects of three large (>70,000 ha) wildfires on key water quality parameters (sediment and organic carbon) in two important forested source watersheds in the Cascade Range of Oregon, US. We calibrated and validated a modified Soil and Water Assessment Tool (SWAT) to simulate streamflow, sediment loads and transport, as well as in-stream organic carbon processes for a historical period prior to wildfire. The calibrated model parameters were then modified based on literature values and burn severity maps to represent post-fire conditions of the three large wildfires. The parameter adjustments for simulating wildfire will be validated with post-fire water quality field samples from the wildfires. We will present estimations of future water quality impacts in the burned watersheds under different precipitation conditions at a daily scale for the first year following the wildfires, which will provide testable hypotheses. Additionally, we will determine catchment characteristics most critical in determining the post-fire water quality response. This work will help predict the magnitude of effects from these historic wildfires, which can inform forest and drinking water management decision making.</p>

In the 21st century, the world had advanced through lots of innovations; its parallel impact in the form of pollutions, global warming and climatic change crisis are being raised. These crises create a gap in terms climatic changes, poor air quality, and unsafe drinking water for the population around the world. Among all pollutants, water pollution is a thrust area as it is a prominent parameter in the food chain of living things. There are huge numbers of diseases that are attributed due to polluted water. The water sources are mainly polluted due to untreated sewage and industry discharges. But mainly industrial wastewater discharge contributes to the accelerated pollution in the water bodies. The proposed design focuses on monitoring the water quality parameters like pH, TDS, TOC, and Chlorine content, conductivity etc., using wireless Sensor Nodes around open ponds and wells near tannery units. The data is transmitted to the cloud, and further information is given to the people through GSM. Repository of data is maintained in order to take it for further analysis. Results obtained from the model indicate the values of the above mentioned parameters.

Water Charges

Governments in developing countries face financial constraints to ensure supply of clean drinking water. They may benefit from increasing water charges for those who are be willing to pay little extra in lieu of their demand for improvement in water quality and service. To check the plausibility of this proposal, we investigated drinking water supply and quality, and welloff consumers demand for improved service delivery in Shah-Rukun-e-alam and Mumtazabad towns in Multan city of Pakistan. Qualitative data obtained through a questionnaire survey was analyzed using descriptive and regression techniques. Qualitative information obtained through semi structured interviews was helpful in designing survey questionnaire and to elaborate quantitative results. Results reveal that the respondents accord high importance to the provision of safe drinking water than to other daily household needs. The demand for improvement in water supply parameters exceeds the demand for improvements in water quality parameters, with the reliable supply being the most demanded improvement. Majority realize the government’s budget constraints in improving service delivery. Most respondents would pay PKR 100 in addition to what they are paying now. Their willingness to pay (WTP) this amount correlates with their awareness on water and health nexus, and depends household income, number of children under 14 years age and awareness of actual water quality tested through laboratory. Besides recommending raise of water charges by PKR 100 per month per household in both towns, the service quality improvement may consider interventions such as mobile water testing laboratory and awareness campaigns motivate citizens to pay for safe drinking water.

The Impact

Gomati River originate from Madhoganj Tanda village in Pilibhit district, U.P. it passes through the district of Shahjahanpur, kheri, Hardoi, Sitapur, Janpur and ultimately merge in Ganga. River water is significant for every living organism as well as aquatic life. Water pollution is a major global problem. Modernization and urbanization have polluted the river water and degraded the status. All over the world we are seeing that drain is the main source of water pollution especially for rivers flowing within the city. This drain generally carries industrial effluent, domestic waste, sewage and medicinal waste resulting in poor water quality. Gomati River receives industrial as well as domestic waste from various drains of Lucknow city. As Gomati river is the only source of surface water near the communities. A total 20 parameters namely Temperature, pH, Turbidity, Conductivity, Total dissolved solids (TDS), Total suspended solids (TSS), Total solids (TS), Dissolved oxygen (DO), Biological oxygen demand (BOD) Chemical oxygen demand (COD), Alkalinity, Total hardness, Calcium as ca, Magnesium as Mg, Chloride, Fluoride, Sulphate as So4, Nickel as Ni, Lead as Pb, and Zinc as Zn where analysed and their variation is discussed to obtain the impact of effluents on water quality. From the result it was found higher than the permissible limit of WHO and BIS.

The Status

Novelties of this study include a synthesis of water quality parameters for the upstream sub-basin of the Dnieper River. This upstream sub-basin includes the Desna River. The synthesis revels new insights on the sources of the water pollution and the status of the water quality for different purposes such as drinking, aquaculture and recreation. The main research objective was to identify the main sources of water pollution and how those sources could decrease the water quality. As a result of our analysis, we conclude the following. The levels of ammonium-nitrogen and nitrite-nitrogen in the Desna River (upstream sub-basin) are by 2-43 times and up to 53 times higher than the water quality thresholds, respectively. This poses a risk for recreational activities since too much nutrients often lead to blooms of harmful algae. We also find an increased level of biological oxygen demand in the river for drinking purposes. For aquaculture, decreased levels of dissolved oxygen are found. Climate change has an impact on water quality. For example, extreme floods caused by too much precipitation can bring pollutants to nearby waters. Monthly average temperature has increased by +2.7 degrees contributing to increased microbiological processes that could stimulate blooms of harmful algae. Main sources of water pollution are sewage discharges in cities, agricultural runoff and erosion activities after floods.
