Studies focused on limnology and quality of water bodies are essential to produce data that support the planning and management, diagnose the current situation and propose measures to minimize the possible negative impacts on water resources. The Tereza Botas creek drains the town of Poconé-MT, situated in the Pantanal border. In this sense, the objective of this study was to verify the variations in limnological characteristics along the longitudinal gradient and evaluate the water quality of the Tereza Botas watershed, identifying the impacts from anthropogenic activities of this important Pantanal watershed. Four sampling points along the longitudinal gradient of the water stream have been defined, and physical, chemical and microbiological variables were analyzed. The results indicated that the changes in limnological and water quality derive from the riparian vegetation removal, erosion and discharge of sewage in natura. In addition, high density of E. coli was observed in most of the sampled points, demonstrating that the lack of proper sanitation as well as the presence of rudimentary cesspit are negatively affecting water quality in the headwaters region.

The conventional technique of measuring the quality of water is to gather the samples manually and send it laboratory for analysis, but this technique is time overwhelming and not economical. Since it is not feasible to take the water sample to the laboratory after every hour for measuring its quality. The water quality measuring system can measure the essential qualities of water in real time. The system consists of multiple sensors to measure the standard of water, microcontroller and wifi modem to send the information to the watching center. It's a true time system which is able to endlessly measure the standard of water and can send the measured values to the watching center when each predefinedtime. During the past decade, water needs have increased unpredictably in India. Increasing demand of water supply has become a major challenge for the world. Wasteful usage of water, climatic changes and Urbanization has further depleted the resource. Conservation and management of the resource must be given utmost importance. In this paper, we present an IoT design for water monitoring and control approach which supports internet based data collection on real time bases. This paper proposes a system that addresses new challenges in the water sector -flow rate measuring and the need for a study of the supply of water in order to curb water wastage and encourage its conservation. We also measure the quality of water distributed to every household by deploying pH and conductivity sensors. The traditional water metering systems require periodic human intervention for maintenance making it inconvenient and often least effective. This system is designed to overcome for shortcoming of the existing models for a ubiquitous usage of wireless systems for smart quality monitoring and communicate datawirelessly.

The quality of water is crucial for the qualification of river beaches. The Cávado River watershed (Northern Portugal) contains five river beaches with a regular and specific mandatory monitorization. The main subject of this research is the evaluation of spatial and temporal water microbiological and physicochemical parameters to assess the water quality improvement and consequently watershed management. The results of monitoring surface water, considering microbiological parameters from the five river beaches (2015/19), and physicochemical parameters from three water points along the Cávado River (2018/19) were considered. The river beaches located upstream of the town of Braga has an “excellent” and “good” quality, while the river beach located downstream shows a lower water quality. The physicochemical water results indicated that there is a progressive degradation of water quality from upstream to downstream of the river, which is associated with the influence of domestic and industrial activities. To improve water quality, continuous monitoring will be necessary, with the implementation of adequate awareness-raising programs and strategic water quality management by the population and local agents.

Os intensos períodos de estiagem e pela concentração que a água adquire quando os níveis dos reservatórios estão baixos torna-se evidente a ausência da qualidade da água consumida pela população. O estudo teve como objetivo avaliar os parâmetros físico-químicos e microbiológicos da água para consumo no município de Itapiúna-CE. Estudo do tipo experimental, prospectivo, transversal e com abordagem do tipo qualitativo e quantitativo. Foram analisadas 4 amostras de 500 mL cada, uma do Açude Castro e de três locais escolhidos nas residências de pontos estratégicos de distribuição pela concepcionária, da água usada para consumo no município de Itapiúna-CE no mês de outubro de 2016. Para seleção das amostras foram adotados os critérios de inclusão: água do açude castro (Amostra A), e três amostras de residências, consideradas a água retirada diretamente do registro da Cagece, escolhidas aleatoriamente dos bairros do município. As amostras apresentaram cloretos alterados quando comparadas às quantidades estabelecidas pela Portaria 2914/2011 do Ministério da Saúde (MS). A respeito aos parâmetros como Sólidos Totais, Condutividade, Cloreto e Dureza, os valores também encontrou-se valores superiores. A amostra A (Açude Castro) obteve pH de 8.81 e apresentou alcalinidade devido a carbonatos (80 mgCO3/L) e a bicarbonatos (150mg CaCO3/L). Verificou-se que 50% das amostras apresentaram presença de coliformes totais e coliformes fecais, evidenciando contaminação da maioria das amostras analisadas. Contudo, de acordo com as análises realizadas, as amostras não obedecem ao padrão de potabilidade, tornando á água imprópria para o consumo humano. PHYSICAL-CHEMICAL AND MICROBIOLOGICAL QUALITY OF WATER FOR CONSUMPTION IN RESIDENCES OF A TOWN IN THE SERTÃO CENTRAL ABSTRACT Factors such as long periods of drought and the physical and chemical characteristics of water influence in the quality of water consumed by the population, leading to health problems. This study aimed at evaluating the physical-chemical and microbiological parameters of water for consumption in the town of Itapiúna-CE. Four samples of 500 mL each were analyzed, one from Açude Castro and three from chosen places in the residences of strategic sites of distribution by the water company for consumption in the town of Itapiúna-CE in October 2016. For sample selection it was adopted the inclusion criteria: water from Açude Castro (sample A), and three samples of residences, considered the water withdrawn directly from Cagece register, randomly chosen from neighborhoods of the town. The samples present altered chlorides compared to the established quantities by the Consolidation Ordinance No. 5 of September 28, 2017 of the Ministry of Health (MS). Regarding the parameters such as total solids, conductivity, chloride and hardness, were also found higher values. Sample A (Açude Castro) obtained pH of 8.81 and presented alkalinity due to carbonates (80 mgCO3 / L) and bicarbonates (150 mg CaCO3 / L). It was verified that 50% of the samples presented total coliforms and fecal coliforms, evidencing contamination of most of the samples analyzed. So, according to the analysis carried out, the samples did not obey the standard of potable water, making the water unfit for human consumption.

Leachate is a liquid generated by mixing of water with organic and inorganic material found in landfills. This liquid accumulates at the bottom of the landfill and has the potential to percolate through the soil to enter groundwater or other water bodies. Leachate contains various contaminants and toxins that can significantly diminish the quality of water it enters, which can become hazardous to humans and the environment. In this article, the water quality of two towns: Egg Harbor and Middle Township, New Jersey were analyzed and compared. Egg Harbor Township has a landfill located within the town, while the closest landfill to Middle Township is approximately 10 miles away. Water supply for both towns comes from the same aquifer, known as the Kirkwood-Cohansey water table system. The water quality results from community wells within Egg Harbor Township were compared to those of Middle Township. Water quality data for this study is from New Jersey American Water database. Based on the results, the water quality of Egg Harbor Township varies significantly from Middle Township. The levels of contaminants in Egg Harbor Township are much higher compared to Middle Township. Therefore, it can be concluded that communities near landfills, even well monitored and managed ones, are prone to have poorer water quality than those farther away from the landfill.

<p>There is huge number of disease which is caused through water drinking that being polluted was supplied to the consumer. This is something that cannot be underestimate because it can cause high cost of treatment or death. Its not only cause troubles to the consumer which is human, it is also included all aquatic life and surrounding ecosystem. There is way to overcome this problem that created before which is take the sample of water to the lab. The result of water being polluted or not will be released by the lab. But this system going to take lot of times because there are few process that should be followed. This system is not suitable anymore because it is not portable, easy and fastest. It should be upgraded to the IoT system because it can cut times, internet base and people will be more alert to the quality of water. Therefore, a real-time water quality monitoring system is proposed in this research to reduce number of fatality happened from water.</p>

From a phenomenological perspective, the reflective quality of water has a visually dramatic impact, especially when combined with the light of celestial phenomena. However, the possible presence of water as a means for reflecting the sky is often undervalued when interpreting archaeoastronomical sites. From artificial water spaces, such as ditches, huacas and wells to natural ones such as rivers, lakes and puddles, water spaces add a layer of interacting reflections to landscapes. In the cosmological understanding of skyscapes and waterscapes, a cross-cultural metaphorical association between water spaces and the underworld is often revealed. In this research, water-skyscapes are explored through the practice of auto-ethnography and reflexive phenomenology. The mirroring of the sky in water opens up themes such as the continuity, delimitation and manipulation of sky phenomena on land: water spaces act as a continuation of the sky on earth; depending on water spaces’ spatial extension, selected celestial phenomena can be periodically reflected within architectures, so as to make the heavenly dimension easily accessible and a possible object of manipulation. Water-skyscapes appear as specular worlds, where water spaces are assumed to be doorways to the inner reality of the unconscious. The fluid properties of water have the visual effect of dissipating borders, of merging shapes, and, therefore, of dissolving identities; in the inner landscape, this process may represent symbolic death experiences and rituals of initiation, where the annihilation of the individual allows the creative process of a new life cycle. These contextually generalisable results aim to inspire new perspectives on sky-and-water related case studies and give value to the practice of reflexive phenomenology as crucial method of research.
