The quality of drinking water flowing in a distribution network can possess corrosive characteristics that may cause the material degradation of pipes and accessories. This problem can result in reduction of the service life of pipes and create a major public health problem. The agreement between the physical-chemical water quality analysis and national standards are not enough to confirm the balance of the water quality in terms of corrosion. In order to predict pipe corrosion in water distribution system networks, the corrosive trend was evaluated using the Langelier (LSI), Ryznar (RSI), and Larson-Skold (LRI) indexes based on measurements of pH, temperature, total dissolved solids, alkalinity, calcium hardness, sulfate and chloride. This study was setup with 180 samples collected in six zones of the distribution network, from July to December of 2017, according to the standard methods for the analysis of drinking water. The results indicate a variation of the LSI from -1.22 to -1.68; RSI from 9.75 to 10.52 and LRI from 0.46 to 0.77. A linear model was fitted for each index to predict the corrosion with the water quality conditions of this study case. Therefore, the drinking water of the city of Azogues, Ecuador has a corrosive tendency from significant to severe. Corrosion indices were calculated to provide useful information on the water's corrosiveness. These results indicate the need to constantly monitor the corrosion rate in the distribution network and conduct a laboratory study to adjust effective parameters such as pH, in order to control corrosion.

“…Water quality is a global issue which requires both environmental and human health evaluations or assessments (Monteiro et al, 2014;Omaka et al, 2015;Sanches et al, 2015). The Water Safety Plan (WSP) is an innovative risk assessment and management approach aimed at ensuring the safety of water for human consumption in the entire drinking water supply system (DWSS), from catchment to consumer (Collivignarelli, 2017).…”

The Water Safety Plan (WSP) approach is an iterative method focused on analyzing the risks of water contamination in a drinking water supply system, from catchment to consumer, in order to protect human health. This approach is aimed at identifying and drastically reducing water contamination in the entire drinking water system, through the identification and mitigation or, if possible, elimination of all factors that may cause a chemical, physical, microbiological and radiological risk for water. This study developed a proposal of WSP for the drinking water supply system (DWSS) of Mortara, Italy, in order to understand which are the preliminary evaluation aspects to be considered in the elaboration of a WSP. The DWSS of Mortara (a town of 15,500 inhabitants, located in northern Italy) consists of three drinking water treatment plants (DWTPs), considering the following main contaminants: arsenic, iron, manganese and ammonia. Potential hazardous events and associated hazards were identified in each part of the water supply system. The risk assessment was carried out following the semi-quantitative approach. The WSP proposal for Mortara was very useful not only as a risk mitigation approach, but also as a cost-effective tool for water suppliers. Furthermore, this approach will reduce public health risk, ensure a better compliance of water quality parameters with regulatory requirements, increase confidence of consumers and municipal authorities, and improve resource management due to intervention planning. Further, some new control measures are proposed by the WSP team within this work.Keywords: arsenic, drinking water, risk assessment, risk management, water safety plan. desde a captação ao consumidor, visando à proteçãoda saúde humana. Objetiva-se identificar e reduzir drasticamente a contaminação da água em todo o sistema de água potável pela identificação e mitigação ou, se possível, a eliminação de todos os fatores que podem causar um risco químico, físico, microbiológico e radiológico para a água. Este estudo desenvolveu uma proposta de PSA para o sistema de abastecimento de água potável de Mortara (Itália), a fim de compreender quais são os aspectos de avaliação preliminar a serem considerados na elaboração de um PSA. O sistema de abastecimento de água potável de Mortara (uma cidade de 15.500 habitantes, localizada no norte da Itália) consiste em três estações de tratamento de água, considerando os seguintes contaminantes principais: arsênio, ferro, manganês e amônia. Eventos perigosos potenciais e riscos relacionados foram identificados em cada parte do sistema de abastecimento de água. A avaliação do risco foi realizada seguindo a abordagem semi-quantitativa. A proposta do PSA para o sistema de abastecimento de água potável de Mortara contribuirá para reduzir os riscos à saúde pública, assegurar um melhor cumprimento dos parâmetros de qualidade da água, dos requisitos regulamentares, do aumento da confiança dos consumidores e autoridades municipais, assim como melhorar a gestão de recursos devido ...

As the impacts of climate change continue to be felt around the world, understanding the effects on groundwater quality and quantity has become an important area of investigation. As a global source of water that contributes to preserving the environment, a better understanding of the effect of precipitation seasonal pattern on these systems is crucial; though studies connected to groundwater quality in this era of environmental crisis are at infancy. This study aims to evaluate the effect of precipitation seasonal pattern on groundwater quality in a coal enriched environment of developing city of west African sub-region with particular reference to Enugu, a coal city in Nigeria. Three residential areas (Abakpa, Achara, and Independence Layout) were randomly selected from high, medium, and low neighbourhood densities in the metropolis. Within the period spanning from April 2018 to March 2019, a physiochemical analysis was conducted on twelve deep wells utilizing weighted arithmetic index method. This technique was implemented in order to facilitate the assessment of the degree of water quality by translating a number of variables to just one metric value. The results of the investigation showed that the groundwater resources in the study region are mildly acidic, presumably as a result of the presence of pyrite, which is a byproduct of coal weathering, and chloride-ion-charged rains. Additionally, noticeable distinctions in the properties of water samples were observed between the dry and rainy seasons. Specifically, just 1% of the sampled water had excellent ratings, while 58.3% were considered good, 29.1% were deemed poor, and 8.3% of samples were categorized as very poor. The study concluded that coupled with climate crisis, seasonal precipitation patterns affect groundwater resources by reducing recharge, discharge, and the overall quality of water. These results have important implications for the management of groundwater resources in the region and highlight the need for continued monitoring and assessment of water quality in the face of ongoing environmental changes.
