Drinking water quality is an actual and stringent problem and the presence of nitrate and nitrite ions above limits imposed by legislation may produce methemoglobinemia and different types of cancer. Because nitrate is odourless, colourless and tasteless is undetectable without tests and well water is recommended to be evaluated from this point of view, especially when in the proximity of the wells are activities which may contribute to water contamination. The present research was carried out with aim to achieve nitrate and nitrite levels from wells located in three areas from Muntenia region: Chiajna (Ilfov), Letca Noua (Giurgiu) and Manastirea (Calarasi). The obtained results evidenced that 10 from 14 analysed wells contain nitrate levels were over imposed limit, one of them located in Manastirea (Calarasi) being even 4 times higher. Regarding nitrite, water from one sampling point is over 0.5 mg/L, all the rest being lower and much lower than imposed limit.

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 reservoirs, maintenance in pipes periodically, as well as the need for continuous monitoring of water quality and the intense participation of public agencies in these actions. Through these actions and the active participation of the population, one can preserve the environment and the lives of all those who transit in the communities of the Bay of All Saints

Access to safe drinking water and potential water degradation have played a role in many water-related investment arbitrations. This paper looks at two different types of investment cases that have emerged with an impact on water: First, it analyses cases that have arisen from privatizations in the water sector. They mainly concern problems connected with physical access to water and affordability. Second, it discusses cases concerning investments in other industries that have the potential to degrade water quality or to have a negative impact on the maritime environment. Using these typical constellations it focuses on the methodology tribunals adopt to deal with potential tensions between the right to water and investor rights.

Determination of the certain major and trace elements was carried out in drinking water supply scheme in three districts of Meghalaya. This work aims to identify trends resulting in the deterioration of drinking water which is also a potential source of environmental contaminants. About 50 samples, each from one district, were collected both from the source and various tanks and tap. The elements determined are Li, Na, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Ag, Au, Pb, Cd, Se, Ca, K, and Mg. The pH is slightly lower than neutral pH of 7 while the turbidity is very high even after treatment. The concentrations of Ca and Mg are found to be deficient. The elements Cr, Fe, Co, Ni, Zn, Mo, and Pb decrease after treatment while Mn, Cu, and Cd increase slightly after treatment. Se concentration is found to be much higher than expected. The results were compared with the standard recommendation values for the quality of drinking water. This study provides a general indication of where water-quality constituent concentrations met or exceeded water-quality standards and the data presented in this report will be useful from public health point of view.

In this study, microbiological quality of drinking water deriving from the private wells from Koprivnica-Križevci County was investigated. A total of 287 samples from different locations were collected during 2018 and analysed for the following microbiological parameters: total coliforms, Escherichia coli, Enterococcus spp., Clostridium perfringens, Pseudomonas aeruginosa, and the number of aerobic heterotrophic bacteria at 36 °C and 22 °C. The results showed that 24 % of the analysed water samples were of unsatisfactory microbiological quality, with high incidence of faecal contamination. Well water is still the main source of drinking water for many residents of this County, especially in its rural parts, so continuous monitoring and disinfection of drinking water deriving from private wells is of exceptional importance for the public health.

The expansion of unconventional oil and gas development (UD) across the US continues to be at the center of debates regarding safety to health and the environment. This study evaluated the water quality of private water wells in the Eagle Ford Shale within the context of community members perception. Community members (n=75) were surveyed regarding health status and perceptions of drinking water quality. Water samples (n=19) were collected from private wells and tested for a variety of water quality parameters. Of the private wells sampled, 8 had exceedences of MCLs for drinking water standards. Geospatial analysis showed the majority of well owners who did have exceedances self-reported their health status as poor. Surveys showed that the majority of respondents received their water from a municipal source and were significantly more distrustful of their water source than of those on private wells. The data also showed a high number of people self-reporting health problems without a healthcare provider’s diagnosis. Attitudes and perceptions of water quality play an important role in the overall perceived health status of community members in high fracking regions, stressing the importance of transparency and communication by the UD industry.

AbstractIron is one of the most common elements in the Earth's crust, which corresponds to it being a common constituent in drinking water supplies. Residents of Bithlo, an unincorporated community in east-central Florida, have observed that their drinking water tastes like metal and stains clothing and teeth. An evaluation of water samples collected from over 200 private drinking water wells revealed iron concentrations that exceeded the US Environmental Protection Agency's (EPA's) secondary standard of 0.3 mg/L. Households with and without point-of-entry treatment were found to have over three times (0.92 mg/L) and ten times (3.86 mg/L) more iron than the EPA's secondary standard, respectively. The human health-based threshold of 4.2 mg/L established by the Centers for Disease Control and Prevention was exceeded in 38.6% of untreated residences. Community-wide statistical and spatial water-quality trends were developed by combining the collected well water quality data with historically available water quality reports. Spatial analyses revealed that greater than 99% of the Bithlo community's private household supplies would exceed the EPA's drinking water secondary standard.

<span>Water quality monitoring is always the prior element to ensure the drinking water is safe to be consumed. A lot of researches have been carried out over the past decades to design and develop a robust and cost-effective water monitoring system. The conventional water monitoring techniques were based on laboratory instruments which is time-consuming and laborious. Furthermore, it is not suitable when the water sampling point is far from the commercial laboratory centres. These limitations were then been solved by the developments of portable testing kits and microwave technique. The microwave techniques such as spectroscopy techniques and microwave sensor approach have improved the water quality monitoring experience which is convenient without sacrificing the measurement accuracy and sensitivity. Its portability enables the on-site measurement at rural areas and thus reduce the transportation and manpower cost. This paper intends to review the water contaminant detection techniques which include standardized drinking water parameter testing and microwave-based in terms of physical, chemical and microbiological parameters. Furthermore, this review also emphasizes the current trend of the water quality testing method in microwave technique. At the end of this paper, a significant advantages and drawbacks of the techniques are summarized, and recommendations are provided for future development in the water quality monitoring.</span>
