The legislation from the European Commission and various other guidelines are discussed in the context of microbiological standards for drinking water. Difficulties in applying these standards are identified and reference is given to the quality control procedures adopted by Anglian Water. Pressures to achieve other drinking water standards, especially trihalomethanes, and the possible need to achieve higher microbiological quality objectives than those regulated currently, could lead to major changes in UK treatment practice.

An important aspect of modeling water quality in water distribution system (WDS) is to predict the temporal and spatial distribution of disinfectant, and the formation of disinfection byproducts (DBP). Consistent efforts have been made to investigate the kinetics of chlorine decay and trihalomethanes (THM) formation in WDS, which are caused by the reaction of chlorine with natural organic matter (NOM). NOM is a heterogeneous mixture of complex compounds. Each specific compound shows individual reactivity with chlorine. Therefore, to better understand and predict the kinetics of chlorine decay

Abstract:
This chapter focuses on water quality violations in America. Most Americans have access to safe drinking water. However, there are pockets of American communities that are afflicted with high levels of contaminated water. In 2015, almost 10% of Americans were drinking contaminated water that violated water quality standards. The chapter then evaluates research at the University of California, Irvine, which examined water quality violations across the United States from 1982 to 2015. Researchers analyzed geographic and temporal patterns, with the goal of helping state enforcement agencies focus their attention on areas at high risk of contamination. The researchers cite decreasing population size and incomes as common obstacles faced by rural populations trying to follow water purification standards. Indeed, rural towns often rely on outside funding and low-interest government loans to support infrastructure to correct water quality violations. However, as of June 2017, over $600 million in grant funding was cut from Environmental Protection Agency drinking water programs. Such cuts, coupled with attempted environmental deregulation, threaten the public’s health.

Abstract:
Water is very significant in the development of a stable community, but many societies are confronted with the challenges of poor wastes management system with indiscriminate waste disposal and bad land practices, which easily pollute water sources and consequently degrade water quality. This study was to analyze the physicochemical properties of ground water from multiple point sources in Jalingo, Taraba state of Nigeria. Water samples were collected from twenty seven (27) sites from the study area during the raining and dry seasons. The analysis was carried out to determining the physico-chemical properties of the ground water and comparing with the World Health Organization (WHO) standard for drinking water. The physicochemical properties of ground water analyzed include; odor, taste, temperature and electrical conductivity were tested in the field using water meter tester. Whereas pH, total dissolved solids, alkalinity, hardness, salinity, iron, manganese, fluoride, nitrate, nitrite, chloride, sulphate and dissolved oxygen were analyzed in the laboratory using Wagtech potable water testing equipment. The physical properties of water analyzed were temperature, odor, taste, and turbidity. Whereas the chemical properties of water analyzed were pH, electrical conductivity (EC), total dissolved solids (TDS), alkalinity, hardness, salinity, iron (Fe), manganese (Mn), fluoride (F−), nitrate (NO3−), nitrite (NO2−), Chloride (Cl−), sulphate (SO42−), dissolved oxygen (DO).The result shows the range of the mean values of the temperature(26.7–33.1) oC, p H(6.5–8.9), Fe (0.01–0.08 mg/L), NO3−(0.01–38.5 mg/l), NO2−(0.01–0.09 mg/l), Mn (0.01–0.17 mg/l), F(0.01–0.82 mg/l), alkalinity(39-204 mg/l), salinity (42-508 mg/l), SO4(14-93 mg/l), total dissolved solids (6–637) mg/l, turbidity(0.4–10.6 mg/l), hardness(48-187 mg/l), and fecal coliforms(1–4)fcu/100mi, dissolved oxygen(1.1–6.87)mg/l, EC(10.99–1066)ohm/cm, Cl (10-320 mg/l). All except alkalinity and hardness are within the WHO permissible standards of quality drinking water. The highest alkalinity (204 mg/l), hardness (187 mg/l) and low dissolved oxygen (6.87 mg/l) attributed to the high concentration of dissolved salts and basic cations in the water. The methodology applied in the study was effective in analyzing the physicochemical properties of water in the study area. Therefore, it was recommended that there should be frequent water source testing by stakeholder in water resources with the view to treating the water. Policy maker should also enforce the regulation of the use of chemical fertilizers, agro-chemicals and the indiscriminate waste disposal.

Abstract:
Southeast Asia, with most of its area receiving an annual rainfall of more than 2000 mm, is a region of positive water balance. It is also an area where unfulfilled demand for water is not unknown. Such a contradiction happens at times in its towns and cities. Several Malaysian urban settlements, for example, suffer occasionally from water shortage in a country with an average annual rainfall of about 3000 mm. Kuala Lumpur went through a prolonged period of water shortage in 1998 (Hamirdin 1998) in spite of large allocations made earlier in various five-year plans towards developing water supply infrastructure. Such shortages are common during long dry periods associated with El Niño. Regional water shortages may become more common in future, especially with the rising population and economic expansion. The shortages are the result of an inability to meet the rising demand of water in cities driven by both increasing population and progressive prosperity. Serious shortage occurs in large cities such as Jakarta, Bangkok, and Manila where a significant proportion of their population has no immediate access to municipal potable water. Even where piped connection exists, supplies are not available round the clock and often do not meet the required water quality standards. In many cities the local sources are inadequate and water has to be brought in from rural areas. The demand for water in a city has to be met on both quantitative and qualitative terms. For example, drinking water supplied to households by a municipal administration has to meet a given standard (WHO 1993). Ideally a city should have enough water to drink, to meet industrial demand, and to be able to store an adequate volume under pressure for firefighting and street cleansing. Supplying a city with water requires water sources, a treatment system, a distribution system, and arrangements for treating waste water and its disposal. In this chapter we review the current status of water supply in urban Southeast Asia and the sources that are available, concentrating on the major cities. We indicate the success stories as well as the shortcomings.

Abstract:
One of the main challenges facing the potable water production industry is deterioration of the quality of raw water. Drinking water that does not meet quality standards is unfit for consumption. Yet, this quality is a function of various factors, key among them being quality of the raw water from which it is processed. This is because costs related to potable water treatment are related to the nature of raw water pollutants and the degree of pollution. Additionally, survival of aquatic species depends on self-purification of the water bodies through attenuation of pollutants, therefore, if this process is not efficient it might result in dwindling of the aquatic life. Hence, this chapter presents spatial and temporal water quality trends along uMngeni Basin, a critical raw water source for KwaZulu-Natal Province, in South Africa. As at 2014 the basin served about 3.8 million people with potable water. Results from this study are discussed in relation to uMngeni River’s health status and fitness for production of potable water treatment. Time-series and box plots of 11 water quality variables that were monitored at six stations over a period of eight years (2005 to 2012), were drawn and analysed. The Mann Kendall Trend Test and the Sen’s Slope Estimator were employed to test and quantify the magnitude of the quality trends, respectively. Findings showed that raw water (untreated) along uMngeni River was unfit for drinking purposes mainly because of high levels of Escherichia coli. However, the observed monthly average dissolved oxygen of 7 mg/L, that was observed on all stations, suggests that the raw water still met acceptable guidelines for freshwater ecosystems. It was noted that algae and turbidity levels peaked during the wet season (November to April), and these values directly relate to chlorine and polymer dosages during potable water treatment.

Abstract:
Governments in developed countries specify water quality standards to be applied in their own countries. Recently the allowance values of harmful metals are getting tighter for environmental water and industrial wastewater throughout the world. For example, World Health Organization (WHO) recommends the criterion value of 3 ppb for cadmium for protection of human health, furthermore, governments of some countries provide the wastewater standard for zinc for conservation of aquatic life. High-performance analytical instruments such as AAS, ICP, and ICP-MS have been employed as official analytical methods of ultra-trace elements. Besides the costly initial and running expenses and the material and energy consuming of the instruments, specific technical skills and long analytical time are required for sample pre-treatment. Therefore, simple yet highly sensitive and eco-friendly on-site methods have been demanded for quick judgment of industrial and environmental water in developed countries as well as evaluation of drinking water in developing countries.

Abstract:
This work aims to evaluate the quality of drinking water in the communities of Baiacu, Sao Francisco do Conde, Santo Amaro and Cachoeira. It was verified that in some places of Santo Amaro and Sao Francisco do Conde, from the microbiological point of view, it is not appropriate for consumption, because it was found that the presence of total coliforms in 50% of the samples and that the chlorine content is below the values indicated by the standards in 75% of the analyzed samples. Thus, the consumption of contaminated water can cause diseases, so it is recommended cleaning of residential reserv

Abstract:
There are several things in life that we take for granted. Water is very often one of them. Each of us uses this vital liquid, the most common substance on earth, everyday. And we rarely think twice about it. Governments and international legislative bodies worldwide are redefining what is “safe to drink.” The United States has led the way by passing into law an amended Safe Drinking Water Act. The European community is considering these standards and the World Health Organization (WHO) provides the impetus for issuing a minimum common standard for the European countries.

The assessment of the carcinogenic risk of the impact of drinking surface waters on the population health of the transboundary basin of the Selenga river in Mongolia is described in the article. We carried out expeditionary studies of the quality of drinking surface waters on the territory of four aimags, which represent different degrees of economic development and are completely included in the Selenga river basin: Khuvsgul, Arkhangai, Bulgan and Selenge. In this work, we used the methodology used by the US Environmental Protection Agency to quantify the carcinogenic risk of exposure to chem

Abstract:
The role of water resources at the present stage of human development becomes more and more significant every year and, actually, just the availability of water resources of required quality limits the further production force growth, city enlargement and the improvement of living standards and industry and agriculture development. The water supply deficit reduction and the water supply level increase are some of the priority national objectives, which are also related to the international obligations of the Republic of Kazakhstan. The prospects for fresh groundwater supply under anthropogenic

Abstract:
In the Republic of Moldova, 57,1% of the population are live in rural areas [23]. Wells and springs in rural areas serve as the main sources of drinking water. Thus, the study carried out in the Poganesti village (Hancesti district) has shown that the main pollution sources in the locality are, especially animal and domestic waste, that have great impact under the quality of drinking water. The study has showed that 55% of the wells, as well as the surface water (small river from the locality) are polluted with nitrogen compounds. Mineralization and total water hardness of the studied wells ex
