Assessment of the water quality of the Seybouse River (north-east Algeria) using the CCME WQI model
This paper aims to assess the surface water quality of the Seybouse River using a model of the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI). The study area is located in the basin of the lower Seybouse River, north-east Algeria. The method involved the calculation of the WQI, based on the measurement of bacteriological and physico-chemical parameters. Water ...

Pollutant Monitoring in Rivers
Water pollution occurs when harmful substances such as microorganisms or chemicals contaminate a body of water. In the UK, a recent parliamentary report has found that the UK’s rivers have been highly polluted by raw sewage, slurry, and microplastics. The pollution comes from many sources, with agriculture and water companies being the biggest contributors. Here we will outline some of the ...

ITOXcontrol safeguards intake Romanian drinking water - Case Study
The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company ...

Microbiological water quality of the Nišava River
Microorganisms are the ideal indicators of the organic pollution of the surface waters because of their ability to promptly respond to environmental changes. Due to poor economic situation and lack of law implementation, most wastewaters in Serbia are released directly into a surface water recipient without any, or a limited, treatment. This practice has created numerous highly polluted ...

Satellite ocean color observations of stormwater runoff plumes alongthe San Pedro Shelf (southern California) during 1997–2003
Knowledge of freshwater runoff plume dynamics in southern California is important for management of coastal water quality, because river discharge associated with episodic winter rainstorms can be a major source of pollutants and pathogens to coastal waters. The purpose of this study was to analyze the spatio-temporal dynamics of plumes at the San Pedro Shelf in southern California and identify ...

Water quality improvement of industrial shrimp ponds
Agriculture has been one of the most major economic sources in Tien Giang province. Because waste generation from ISP process has not been completely controlled, it has affected the water quality seriously. Samples collected at three stages of shrimp ponds and surface water (rivers, canals) were assessed. The results showed that water quality in rivers and canals is contaminated by organic and ...

Use of horizontal flow roughing filtration in drinking water treatment
In order to evaluate the feasibility of implementation of horizontal-flow roughing filtration for drinking water treatment a pilot was designed and run at the bank of Zayandehroud river near the village of Chamkhalifeh. Pilot running was performed in summer 2003 (July, August and September), when the quality of river water was in relatively worst condition. The filter is comprised from three ...

Spatial variation of water quality in upper catchment of Miyun Reservoir
Miyun Reservoir is the main surface source of drinking water for Beijing, China. Water eutrophication has compelled authorities to improve the water quality in its upstream catchment. However, a water-quality survey of the entire catchment was lacking. A total of 52 monitoring sites covering the entire catchment were sampled approximately monthly from July–September 2013, in response to ...

Differential water quality in confined and free-flowing water bodies, Lebanon
Integrated management of water resources is a major critical issue to be addressed in combating water stress in developing countries, such as Lebanon. At present, surface water is not properly used in Lebanon. This emphasises the importance of assessing surface water quality as a projected means to increase water availability. This study involves two different water bodies, the freely flowing ...

Stormwater runoff plumes observed by SeaWiFS radiometer in the Southern California Bight
Abstract Understanding the factors that influence the incidence and dispersal patterns of freshwater runoff plumes in southern California is important for management of coastal water quality. Significant river discharge is associated with episodic winter rainstorms, leading to turbid pollutant and pathogen-laden stormwater plumes that are clearly visible nearshore in the Southern California ...

Textile Industry Water Use and Treatment
As the industry turns toward sustainability, decentralized water reuse has potential to reduce ‘virtual water’ toll The textile industry is water-intensive throughout its many processes: sizing, desizing, mercerizing, scouring, bleaching, printing, and finishing. Beyond processing, water footprint calculations often neglect the use of significant amounts of “virtual ...

Toxicity Monitoring of the Scheldt and Meuse Rivers in Wallonia (Belgium) by Conventional Tests and Microbiotests
Abstract : The Microtox acute toxicity test using the luminescent bacterium Vibrio fischeri, was chosen as a complementary descriptive parameter of toxic pollution in the framework of monitoring surface water quality in Wallonia, Belgium. In order to examine the samples on a routine basis, ensure a cost-effective approach adapted to the dilution effects, and enhance the sensitivity of the system, ...

Estimation of surface water quality in a Yazoo River tributary using the duration curve and recurrence interval approach
Pollution of surface water with harmful chemicals and eutrophication of rivers and lakes with excess nutrients are serious environmental concerns. This study estimated surface water quality in a stream within the Yazoo River Basin (YRB), Mississippi, USA, using the duration curve and recurrence interval analysis techniques. Data from the US Geological Survey (USGS) surface water monitoring ...

Principal component analysis of surface water quality data of the River Drava in eastern Croatia (24 year survey)
The River Drava is one of the major, inexhaustible water sources not only for Croatia, but also for the other European countries it flows through. This study is based on the observations of 15 water variables at three sampling stations in the lower River Drava over a 24 year period. Although the obtained results revealed an improvement of most of the parameters, the values of some of them (i.e. ...
