− The quality of water hold on important rule in the field of fisheries, especially in cultivation activities. Parameters of water quality are often observed such as temperature, pH, salinity, and others. The influence of water quality on cultivation activity is very important therefore supervision of water quality parameters is absolute done by cultivators. This research  had created the quality of water monitoring system in fishponds wirelessly. The system consist of the transmitter that integrated with LM35 sensor, pH meter kit sensor and conductivity sensor as measurer of water quality, and the receiver receive datum transmitted wirelessly with nRF24L01 module a long 5 meters distance from transmitter. The receiver equipped with an interface with PC which can save data measurement automatically to Microsoft Excel. The results of the validation of the measurement instrument obtained  average of error relative to measurement were 0.01 0C for temperature, 0.005 for pH and 0.008 ppt for salinity. In summary, the measurement of water quality in surface water fishponds of temperature is 29oC until 38oC, pH is 8,6 until 11,9 and salinity is 12 until 21 ppt.

Security of supply of water, which meets the quality parameters specified in applicable standards, is now the basis for the functioning of most societies. In addition to climatic, biological, chemical, and physical hazards, it is worth paying attention to consumers’ subjective perception of the quality of tap water supplied in the area of Poland. The article discusses various activities related to water resources management and analyses the results of an evaluation of selected quality parameters of tap water in Poland. A novelty on a European scale here is an examination of the evaluation of these parameters based on potential seasonal differences (spring, summer, autumn, winter). For the first time in the world literature, PROFIT analysis was used to evaluate selected parameters of tap water quality. The aim of the article was to present a model for the evaluation of the parameters of tap water supplied in different seasons of the year in Poland. Due to the complexity of the research aspects, a mixed-methods research procedure was used in which a literature review was combined with a survey and statistical analysis. For the purpose of the survey, an original survey questionnaire called “Survey of customer opinions on selected parameters of tap water supplied in Poland” was developed especially for this study. The conducted research confirmed the adopted hypothesis that the results of evaluation of selected tap water parameters vary depending on the period (spring, summer, autumn, winter) in Poland. The model developed by means of PROFIT analysis makes it possible to highlight to water suppliers the specific quality parameters in particular seasons of the year (spring, summer, autumn, winter), which may improve the quality of water supplied in Poland and thus, in the long-term perspective, increase the level of satisfaction of water recipients and confidence in drinking tap water in Poland.

Water quality of the Indus River around the upper basin and the main river was evaluated with the help of statistical analysis. In order to analyze the similarities and dissimilarities for identifying the spatial variations in water quality of the Indus River and sources of contamination, multivariate statistical analysis, i.e., principle component analysis (PCA), cluster analysis, and descriptive analysis, was done. Data of 8 physicochemical quality parameters from 64 sampling stations belonging to 6 regions (labeled as M1, M2, M3, M4, M5, and M6) were used for analysis. The parameters used for assessing the water quality were pH, dissolved oxygen (DO), oxygen reducing potential (ORP), electrical conductivity (EC), total dissolved solids (TDS), salinity (%), and concentration of arsenic (As) and lead (Pb), respectively. PCA assisted in extracting and recognizing the responsible variation factors of water quality over the region, and the results showed three underlying factors including anthropogenic source pollution along with runoff due to rain and soil erosion were responsible for explaining the 93.87% of total variance. The parameters which were significantly influenced by anthropogenic impact are DO, EC, TDS (negative), and concentration of Pb (positive), while the concentration of As, % salinity, and ORP are affected by erosion and runoff due to rain. The worst pollution situation for regions M1 and M6 was due to the concentration of As which was approximately 400 μg/l (i.e., 40 times higher than minimum WHO recommendation). Furthermore, the results also indicated that, in the Indus River, three monitoring stations and five quality parameters are sufficient to have a reasonable confidence about the quality of water in this most important reserve of Pakistan.

A má qualidade dos corpos de água exerce influência direta sobre a saúde da sociedade, podendo causar doenças de veiculação hídrica, que levam a morte milhões de pessoas no mundo. Neste cenário, o presente estudo objetivou identificar as relações existentes entre condições ambientais e doenças de veiculação hídrica no Assentamento Rural Serra Grande, situado na sub bacia hidrográfica do Riacho Natuba, no município de Vitória de Santo Antão, em Pernambuco. Foram escolhidas seis nascentes, fazendo-se medições de parâmetros de qualidade de água, comparando-se os resultados das análises com os padrões estabelecidos pela Resolução Conama Nº 357/05 e Portaria do Ministério da Saúde Nº 2914/11. Para identificar a ocorrência de doenças de veiculação hídrica no assentamento procedeu-se a aplicação de questionários junto à comunidade local, representantes do Posto de Saúde e da Secretaria de Saúde Municipal, abordando aspectos sobre a incidência dessas doenças e respectivos programas de saúde implementados. Os resultados obtidos mostraram que as nascentes representavam a principal fonte de água para o consumo doméstico, a irrigação e a dessedentação animal. No entanto, as análises de qualidade de água apontaram que a mesma não apresentava condições apropriadas ao consumo humano direto, requerendo prévio tratamento. Em relação ao perfil de ocorrência das doenças de veiculação hídrica, constatou-se que as verminoses e protozooses são as doenças que mais acometem a população.   A B S T R A C T The poor quality of water bodies shall exercise direct influence on the health of society, causing hydro term placement diseases leading to death millions of people worldwide. In this scenario, the present study aimed to identify the relationship between environmental conditions and hydro term placement diseases in the Rural Settlement Serra Grande, located in the Sub-basin of the Natuba rivulet, in the municipality of Vitória de Santo Antão, Pernmbuco State, Brazil. Six springs  were chosen for sample collections and determination of  water quality parameters, comparing the results with the quality standards established by CONAMA ( Brazilian National Environmental Council) Resolution Nº 357/05 and Ordinance of the Ministry of Health (Brazil) No. 2914/11. Questionnaires were applied to local social actors: community, health and Municipal Health Secretariat, addressing aspects of water diseases and health programs implemented. The results obtained showed that the springs were the main source of water for domestic consumption, irrigation and animal watering in the studied area. However, the water quality analyses showed that these springs  do not show appropriate sanitary conditions to direct human consumption, requiring treatment. In relation to the profile of hydro term placement diseases occurrence, it was observed that the worms and protozooses are the diseases that most affected the local population. Keywords: Management of water resources, quality of the water, health and environment.

Context Water is the first nutrient and an essential component of all agricultural production systems. Despite its importance there has been limited research on water, and in particular, the impact of its availability, management and quality on production systems. Aims This research sought to describe the management and quality of water used within the Australian pig industry. Specifically, the water sources utilised, how water was managed and to evaluate water quality at both the source and the point of delivery to the pig. Methods Fifty-seven commercial piggeries across Australia participated in this study by completing a written survey on water management. In addition, survey participants undertook physical farm parameter measurements including collecting water samples. Each water sample was tested for standard quality parameters including pH, hardness, heavy metals and microbiological status. Key results Responses were received from 57 farms, estimated to represent at least 22% of ‘large’ pig herds. Bore water was the most common water source being utilised within the farms surveyed. Management practices and infrastructure delivering water from the source to the point of consumption were found to differ across the farms surveyed. Furthermore, water was regularly used as a delivery mechanism for soluble additives such as antibiotics. The quality of water at the source and point of consumption was found to be highly variable with many parameters, particularly pH, hardness, salinity, iron, manganese and microbiological levels, exceeding the acceptable standard. Conclusions In general, water quality did not appear to be routinely monitored or managed. As a result, farm managers had poor visibility of the potential negative impacts that inferior water quality or management may be having on pig production and in turn the economics of their business. Indeed, inferior water quality may impact the delivery of antibiotics and in turn undermine the industry’s antimicrobial stewardship efforts. Implications The study findings suggest that water quality represents a significant challenge to the Australian pig industry. Access to drinking water of an acceptable quality is essential for optimal pig performance, health and welfare but also to ensure farm to fork supply chain integrity, traceability and food safety.

Aboisso region is experiencing unprecedented agricultural activities. Cultural techniques such as the use of insecticides are harming the quality of water. This study aims to assess the impact of insecticides on the water quality in the Aboisso region. Thirty-one (31) water points (10 surface water and 21 groundwater) were sampled. The determination of physicochemical parameters as well as the multi-residue method used for insecticides analysis in the samples allowed us to achieve our objective. The result of the physicochemical analysis shows that the temperature of groundwater (27.91°C) is higher than surface water temperature (26.77°C). These waters are mostly acidic with a slightly lower pH for groundwater (6.46) compared to surface water (6.54). The conductivity is higher in groundwater (average of 130.46 µS/cm) as opposed to surface water (average of 43.50 µS/cm). After applying the multi-residue method, the results reveal the presence of nine (9) active ingredients. In surface waters, all these molecules, except Lambda-cyhalothrin and Deltamethrin, exceed the WHO guide values (0.1 µg/L). The highest concentrations recorded concern ethyl parathion and profenofos (8.24 µg/L and 8.04 µg/L respectively). In groundwater, it is rather Parathion-methyl, Profenofos, Dimethoate, Chlorpyriphos-ethyl, Lambda-cyhalothrin and Deltamethrin that are often at below WHO standards. However, the present study reveals that all of the water samples analysed were polluted, owing to anthropogenic used of insecticides in the region, and other chemicals with high concentrations of parathion-ethyl: 8.24 µg/L and profenofos: 8.04 µg/L. These waters are therefore unfit for human consumption.

Predictions of future events must be factored into decision-making. Predictions of water quality are critical to assist authorities in making operational, management, and strategic decisions to keep the quality of water supply monitored under specific criteria. Taking advantage of the good performance of long short-term memory (LSTM) deep neural networks in time-series prediction, the purpose of this paper is to develop and train a Long-Short Term Memory (LSTM) Neural Network to predict water quality parameters in the Selangor River. The primary goal of this study is to predict five (5) water quality parameters in the Selangor River, namely Biochemical Oxygen Demand (BOD), Ammonia Nitrogen (NH3-N), Chemical Oxygen Demand (COD), pH, and Dissolved Oxygen (DO), using secondary data from different monitoring stations along the river basin. The accuracy of this method was then measured using RMSE as the forecast measure. The results show that by using the Power of Hydrogen (pH), the dataset yielded the lowest RMSE value, with a minimum of 0.2106 at station 004 and a maximum of 1.2587 at station 001. The results of the study indicate that the predicted values of the model and the actual values were in good agreement and revealed the future developing trend of water quality parameters, showing the feasibility and effectiveness of using LSTM deep neural networks to predict the quality of water parameters.

Part of the drinking water demands of the city of Amsterdam and the surrounding district are met by abstraction from nearby Lake Loenderveen that is fed by two different kinds of surface water. The lake itself is subject to rainfall, evaporation and seepage. It acts partly as a stockpiling reservoir (about 2 weeks) and partly as a self-purifying medium (retention time about 100 days). The design and management of the lake are such that a high degree of mixing of the inflowing water is obtained and an almost constant water quality, which greatly facilitates subsequent treatment to obtain high quality drinking water. To combat eutrophication the nutrient-containing water that enters the lake is dephosphated. After a number of years working with an experimental and simplified method in the lake itself, a highly efficient new coagulation and settling plant was constructed. This has been in operation since 1984. The improvements in the quality of the lake water are discussed in this paper. In addition to a considerable reduction in the phosphate content (and that of other nutrients), improvements were registered in a number of other water quality parameters (DOC, heavy metals, colour c.a.). A similar coagulation and settling system is also used to treat one kind of surface water that is fed into the adjacent Loosdrecht Lakes during dry summer spells. These lakes are of great environmental importance; they are also unique features of the landscape. Pretreatment of the water that flows into the lakes has a substantial effect on the water quality. A monitoring system has been set up to check the resulting improvement.

Different multivariate statistical techniques were used to evaluate temporal and spatial variations of surface water-quality of Fuji river basin using data sets of 8 years monitoring at 13 different sites. The hierarchical cluster analysis grouped thirteen sampling sites into three clusters i.e. relatively less polluted (LP), medium polluted (MP) and highly polluted (HP) sites based on the similarity of water quality characteristics. The principal component analysis/factor analysis indicated that the parameters responsible for water quality variations are mainly related to discharge and temperature (natural), organic pollution (point sources) in LP areas; organic pollution (point sources) and nutrients (non point sources) in MP areas; and organic pollution and nutrients (point sources) in HP areas. The discriminant analysis showed that six water quality parameters (discharge, temperature, dissolved oxygen, biochemical oxygen demand, electrical conductivity and nitrate nitrogen) account for most of the expected temporal variations whereas seven water quality parameters (discharge, temperature, biochemical oxygen demand, pH, electrical conductivity, nitrate nitrogen and ammonical nitrogen) account for most of the expected spatial variations in surface water quality of Fuji river basin.

At present, the condition of surface water is much declining and the quality of water is a vital concern for mankind. It is directly linked with human security. Greater part of people is still not aware of it. So, improvement of the condition of surface water is a crying need. Surface water is often physically contaminated due to unhygienic practices. Discharges from various contaminated sources are very common thing in city life which deteriorates the water quality and necessary treatment is required to make water usable. The investigation is based on laboratory tests on water samples obtained from seven Ponds and three Charas of Sylhet City Corporation. The selected parameters for assessing the water quality are PH, Biochemical Oxygen Demand (BOD) and Dissolved Oxygen (DO). The present condition of Ponds and Charas water are not up to the mark and it is declining day by day. Proper initiatives need to take regarding the control of surface water pollution in Sylhet.
