What are the methods of water quality analysis?
Water quality analysis is a crucial step in ensuring that the water we consume is safe for our health and the environment. It involves the examination of the physical, chemical, and biological characteristics of water to determine its suitability for various purposes. There are several methods of water quality analysis, each with its advantages and limitations. In this blog post, we will explore ...

Water quality analysis of reservoirs within Western Algeria catchment areas using water quality index CCME WQI
The present paper aims at determining the status and trends in water quality at Western Algeria reservoirs. The method consists of the computation of Water Quality Index (WQI) on the basis of the physical–chemical quality parameters that were registered at the monitoring stations placed at the reservoirs. This WQI was applied to water quality data collected from 2001 to 2010. Results ...

Diurnal fluctuation of zinc concentration in metal polluted rivers and its potential impact on water quality and flux estimates
Diurnal fluctuations of metals have been observed in the South Tyne river catchment, UK, in both upland tributaries and major river reaches. Zinc exhibits the most pronounced cyclicity, with concentrations increasing during the night to a maximum near 05:00 before decreasing during the day. This trend is the inverse of pH and temperature observations, which are thought to be the predominant ...

Spatial analysis of water quality using a combination of GIS and statistical software
GIS-based spatial analysis was combined with statistical analysis to process time varying water quality data. A data model was employed to manage the spatio-temporal data. The spatial data engine of ArcSDE was used to access the database. A data relationship model was developed to perform data communication between GIS and the statistical software. Visual Basic was used to construct links between ...

Characterizing water quality monitoring visualization with Hadoop and Google Maps
In water quality monitoring, the complexity and abstraction of water environment data make it difficult for staff to monitor the data efficiently and intuitively. Visualization of water quality data is an important part of the monitoring and analysis of water quality. Because water quality data have geographic features, their visualization can be realized using maps, which not only provide ...

Assessment of water quality observation stations using cluster analysis and ordinal logistic regression technique
Variations in the surface water quality parameters of the observation stations have been investigated using cluster analysis and the ordinal logistic regression technique. Ordinal logistic regression analysis results showed that nitrite, ammonium and total phosphorus were identified as the parameters that displayed essential variations. These results were supported by the cluster analysis. The ...

Water Ion Sensor-Water Ion Monitoring
About- Water Ion Sensor Ion sensor is a sensor that uses ion selective electrode to convert the amount of ions felt into usable output signal. Ion sensor is a selective measurement of the concentration (activity) of specific ions in solution. It has been 20 years since its development and plays an extremely important role in all scientific fields. In recent years, due to the development of ...

Lake Edku water-quality monitoring, analysis and management model for optimising drainage water treatment using a genetic algorithm
Lake Edku, one of the northern Nile Delta Lakes, subjected to huge inputs of nutrients (especially phosphorous and nitrogen). These nutritional conditions create rich resource spectrum for algal growth and make the lake suffer from high level of eutrophication. Lake Edku does not have numeric water quality criteria for nutrients. The main objective of this research is to develop a model which can ...

Assessment of emerging hydrological, water quality issues and policy discussion on water sharing of transboundary Kabul River
Transboundary water sharing policy between Pakistan and Afghanistan along with emerging issues over the Transboundary Kabul River have been discussed incorporating long-term hydrological trend analysis, water quality issues and temporal changes in land cover/land use. The annual (1977–2015) mean river flow of 26.32 billion (109) cubic metres (BCM) with a range of 13.77 to 42.2 BCM and ...

Drinking water quality monitoring using trend analysis
One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...

Surface water quality assessment of Amingaon (Assam, India) using multivariate statistical techniques
The pollution of surface water has become a global environmental issue. Monitoring of surface water is essential to know the current status of water quality and maintain it at certain desirable level. In this study surface water quality of Amingaon has been analysed. Amingaon is a locality in North Guwahati (Assam, India). In last few decades’ the locality has undergone rapid and uncontrolled ...

Determination of water quality index by fuzzy logic approach: a case of ground water in an Indian town
The paper proposes fuzzy logic model that deals with the physico-chemical water analysis of ground water of Chikhli town for determination of Water Quality Index (WQI). The study was carried by collection of ground water samples from about eleven hand pumps located in this town. Ground water quality is studied by systematic collection and analysis of samples. The fuzzy logic is used for the ...

Effect of age and rainfall pH on contaminant yields from metal roofs
Metal roofs are recognized for conveying significant metal loads to urban streams through stormwater runoff. Metal concentrations in urban runoff depend on roof types and prevailing weather conditions but the combined effects of roof age and rainfall pH on metal mobilization are not well understood. To investigate these effects on roof runoff, water quality was analysed from galvanized iron and ...

Topological clustering as a tool for planning water quality monitoring in water distribution networks
Topological clustering was explored as a tool for water supply utilities in preparation of monitoring and contamination contingency plans. A complex water distribution network model of Copenhagen, Denmark, was simplified by topological clustering into recognizable water movement patterns to: (1) identify steady clusters for a part of the network where an actual contamination has occurred; (2) ...

Dairy Wastewater: Identify and Reduce Product Loss with Real-Time BOD/COD Monitoring
LOST PRODUCT = LOST REVENUE Manufacturers in the food and beverage industry lose significant quantities of product in the production process. In the dairy industry, milk losses are on average 2-3% of total production and can be even higher for ice creams and novelty products. While it seems like a relatively small percentage, these losses can equate to a large volume of product lost every year, ...

Can harmful algal blooms be predicted?
Summer 2015, as the eighth month of the year approaches (August), we are starting to hear and read in the news about sudden algal blooms occurring in freshwater lakes and marine environments. Many popular beach resorts have put up warning signs proclaiming the water is unsafe for recreational purposes. This is an understandable precautionary measure since phytoplankton abundance or more ...

Yucca Mountain Project, Nevada -
Wells J-12 and J-13 are located in Area 25 of the Nevada Test Site near Mercury, Nevada. These wells supply potable water for the Yucca Mountain Project. Water-quality analyses revealed that arsenic concentrations exceeded the new maximum contaminant level (MCL). Before choosing a technology, the site manager, Bechtel SAIC, contracted with Dr. Dennis A. Clifford, University of Houston, and a ...

Parameter identification of river water quality models using a genetic algorithm
For solving the multi-parameter identification problem of a river water quality model, analytical methods for solving a river water quality model and traditional optimization algorithms are very difficult to implement. A new parameter identification model based on a genetic algorithm (GA) coupled with finite difference method (FDM) was constructed for the determination of hydraulic and water ...
