Water quality information is needed to assess the state of water contamination in a variety of community, including those that rely primarily on unimproved underground sources of drinking water. The study was carried out with an aim to assess the quality of ground water in particular sites of the Kathmandu valley. The ground water samples were collected from shallow well, tube well and deep tube wells located at specific places of the valley. The research was focused on physiochemical and bacteriological analysis of underground water from sites near to Bagmati river (≤20 meters) and from sites far from Bagmati river (>50 meters). The sampling sites were scattered from Sinamangal to Minbhavan. Total sample size was 100, with 50 in each stratum. Study processing was done during the period from February 2013 to May 2013. Six physiochemical parameters namely pH, Conductivity, Ammonia level, Chloride level, Nitrite level, Nitrate level and Biological parameters (Coliform and Fecal coliform) of each sample was tested. Based on the research work, it was recorded that the underground water close to river (≤20 meters) has comparatively high physiochemical and biological parameter (Fecal Coliform) than underground water that were farther from the river (>50 meters). Fecal Coliform was predominant 58% (29/50) in water nearer to river rather than in water farther from the river 20% i.e. (10/50).  Similarly, the values of physiochemical and biological parameter increased comparatively with more distance i.e. ≤10 meters from river. The finding indicated that the underground water near to river is more polluted than far from the river.Nepal Journal of Biotechnology. Dec. 2017 Vol. 5, No. 1:21-26

Underground water is extracted by wells that are connected through underground canals. Thus, the levels of pollutant elements in ground water could be evaluated directly from water samples collected from the wells. This study was conducted in the city of Samara / Salah-Aldeen province – Iraq. The samples were taken from 29wells within the study area for the period 2012-2014 with a supervision from the General Authority for Groundwater / the Iraqi Ministry of Water Resources. GIS technology was adopted to calculate the pollution elements at Samara water table. The concentrations of chemical elements [K, Na, Mg, Cl, Ca] and compounds [SO4, HCO3] were manipulated and calculated for the entire area. The results of laboratory analyses showed that the groundwater in this area is not suitable for use as drinking water for humans, since the concentrations of the chemical elements and the compounds exceeded the permissible limits and are not in accordance with WHO standards. However, the results also indicated that the groundwater in the covered area is suitable for agriculture irrigation.

The problem of arsenic in drinking water, which causes a violation of human health, is revealed. The main ways of arsenic ingress from the lithosphere into drinking water are shown. In the earth's crust, arsenic is contained in rocky rocks, from where it under the influence of weathering processes passes into sedimentary rocks, alluvium and silts. When underground water passes through a section of the earth's crust containing arsenic in the form of its minerals, the water is saturated with arsenic. Chemical reactions of arsenic transition to easily soluble forms and its main compounds in natural waters are presented. The mechanism of arsenic migration in natural surface and underground waters is explained. In Bangladesh, about 60 million people use arsenic-contaminated groundwater as drinking water and are therefore at risk of poisoning. Detailed map of the world on the risk of arsenic contamination of natural fresh water. It is shown that in Kazakhstan there are numerous geogenic deposits and ore occurrences of arsenic, which naturally infect groundwater. The West Kalba ore belt, which is about 800 km long and 80-100 km wide, has been identified only within Eastern Kazakhstan, and its ore objects are represented by gold-arsenopyrite (with an arsenic content of up to 2-5 %) ores. In addition, Kazakhstan has a significant technogenic component of arsenic water pollution due to the influence of the mining industry: only in the dumps of the Ust-Kamenogorsk metallurgical plant, more than 300 thousand tons of arsenic mineral products have already accumulated, with an annual increase of 11 thousand tons. The method of disposal of such waste, as well as localization of arsenic from underground polluted waters on technogenic geochemical barriers, is described.

Human beings require potable water for drinking to keep them healthy. Clean, safe and adequate fresh water is vital to the survival of all living organisms. Drinking water affects the health of human beings due to the presence of various dissolved chemical constituents. Problems arising out of chemical constituents in drinking water are different from the problems of microbial contamination. Therefore, consumers should have at least minimum knowledge on quality of drinking water. People across the world depend on ground water for drinking. Ground water is a major source, so based on the importance of the matter; a research topic is taken up on the assessment of quality of groundwater in the selected areas of villages in Veeraghattam and Palakonda Mandals of Srikakulam District, Andhra Pradesh. This preliminary study assessed the quality of physical and chemical characteristic properties of underground water in the selected locations of 40 villages in Veeraghattam and 39 villages in Palakonda Mandals of Srikakulam District. Some physico chemical characteristic parameters are estimated in the samples and the results obtained are compared with the available standard values such as WHO and BIS.

The quality of water resources in Morocco is degraded by pollution from agriculture, industry and urbanization. In this work we have realized a comparative study of two groundwater pollution zones: M’nasra (Kenitra) and Sfafaa (Sidi Slimane). In general, the results of this study showed that most water wells are strongly mineralized as the conductivity far exceeds the standard of drinking water. Sodium chloride (NaCl) concentration is between 33.9 and 1184.6 mg / l and shows some of the wells are loaded with salts. The pH is generally basic in all wells. Pollution by nitrates two regions showed that the ground water is strongly affected M’nasra zone terms of the permeability of the soil of the city. The concentration of nitrate can reach high values compared to the results obtained on the ground water at Sfafaa zone whose nitrate concentrations around 20 mg/l. Further pollution of groundwater in the two regions of the shows values of organic matters that go far beyond the standards of drinking.

A source of clean drinking water is essential, and the Aztecs were quite advanced in providing it. While London still drew its drinking water from the polluted Thames River as late as 1854, the Aztecs brought potable water to Tenochtitlán from springs on the mainland by means of the aqueduct built by Nezahualcoyotl between 1466 and 1478. A second aqueduct was constructed in 1,499–1,500 by the ruler Ahuizotl when the first aqueduct became inadequate. Although the Aztecs had no citywide drainage system, and much of the wastewater ended up in the lake surrounding the city, they had a system to handle human waste by means of privies in all public places and many private dwellings from which excrement was collected in canoes. The excrement was applied as fertilizer to chinampas (floating parcels of land) or sold in the market to be used for tanning animal hides. Urine was collected in pottery vessels to be used later as a mordant for dyeing cloth. The Tenochtitlán environment was obviously healthy for its time, especially in comparison to European cities. Public and personal hygiene contributed to minimize the incidence and severity of illnesses.

The Paris drinking water system has the particularity of being supplied by many different sources: surface water from the Seine and Marne rivers and underground water from sixty-three springs. This diversity of origins of the water and the existence of a gridded network leads the company in charge of the production and the quality of the water in Paris, Sagep, to partly mix the water in the network. Knowing the impact of the mixing on the physical parameters, and consequently on the quality of this mixed water, Sagep had searched for a tool to control the water origins in the network in order to limit extreme changes. A study led Sagep to develop a new kind of real-time water mixing model.
