  • Treatment of polluted river water by a new constructed wetland

    Abstract: A new constructed wetland was built to purify one polluted river in Taiwan, and this study was conducted to evaluate the treatment efficiency of the wetland. Due to the very limitation of available budget, several water quality items, which were stipulated by Taiwan’s Environmental Protection Administration for rivers, in the influent and effluent of wetland were analyzed and ...

  • Current pollution status of Yangtze River and controlling measures

    The concentration of Persistent Organic Pollutants in Yangtze River in China is increasing steadily, especially in the downstream, where the drainage is often discharged into the water body without any treatment. In this study, the pollution status, trend of mainstream and Three Gorges area are analysed based on the statistical data of the water quality in the past years. Results indicate that ...

  • River water pollution in Indonesia: an input-output analysis

    Data from global environmental monitoring activities have shown alarming environmental conditions in many developing countries. Environmental policies that could improve the environment significantly, while at the same time maintaining the growth of economic activities are needed. Using an input-output analysis, this paper researches such policies with a view to applying them to Indonesia's river ...

  • Water quality assessment of a polluted urban river

    Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the prioritisation of different areas of the basin for ...

  • Study of metal pollution in Sembrong River, Johor, Malaysia

    Sampling of the Sembrong River over a 9-month period revealed maximum total aluminium (Al), ferum (Fe) and manganese (Mn) concentrations of 61.0, 33.0 and 1.5 mg/L, respectively, and pH as low as 2.5, making it one of the most metal- and acid-contaminated rivers in Malaysia. The river serves as a fresh water source to water treatment plants located at the downstream reach of the river, which ...

  • Spatial distribution of groundwater pollution in the Porsuk River Basin (PRB), Turkey

    The groundwater in the alluvium aquifer of the Eskisehir Plain (EP) is polluted by wastewaters transported through Porsuk River, agricultural-industrial activities, river-groundwater interactions and unsanitary landfill. Porsuk River flows throughout the alluvium aquifer in the EP. In this study, the effects of anthropogenic activities on groundwater quality in the EP were investigated. Since the ...

  • Combating river pollution in China and India: policy measures and governance challenges

    Severe water pollution is among the top policy priorities in both China and India. This paper undertakes a comparative case analysis to examine efforts in combating river pollution in two major rivers – the Yangtze in China and the Ganga in India. Our analysis suggests that efforts in combating river pollution in the two Asian giants have encountered substantial challenges, such as the lack of ...

  • The impact of point sources of pollution on the transport of micropollutants along the river continuum

    The main objectives of the presented study were to quantify the transfer of polychlorinated dibenzo-p-dioxins (PCDDs)/polychlorinated dibenzofurans (PCDFs) (polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans) and dioxin-like polychlorinated biphenyls (dl-PCBs) along the river continuum and to evaluate the impact of wastewater treatment plants (WTPs) located in ...

  • Aquatic pollution in Mithi River of Mumbai: assessment of physico–chemical parameters

    The present investigation along Mithi River of Mumbai deals with the study of physico–chemical parameters like pH, conductivity, solid content, hardness, chloride, sulphate/sulphide, phosphate, biochemical oxygen demand (BOD), chemical oxygen demand (COD), surfactants, oil/ grease and phenol content in river water samples. The study was performed for the period of two years from 2009 to 2011, at ...

  • Economic analysis of alternative pollution abatement policies: the case of Buriganga River, Bangladesh

    The Buriganga River is a prime example of serious surface water pollution problem. So far the emphasis of pollution abatement policy for this river has been solely on the application of command and control (CAC) mechanisms (standards on emission discharges), however little success has been achieved as the polluters seem to be reluctant to comply to these measures. This study evaluates the ...

  • Treatment of Polluted River Water Using Pilot-Scale Constructed Wetlands

    From 1970S TO 1980S, the Constructed Wetland (CW) technique has already been rapidly developed and widely applied in more than 10 countries, such as USA, Australia and countries, such as USA, Australia and countrien in Europe (Amelia, 2000; Brown, et al. 1994; Haberl, et al., 1995). Nowadays, there have been about 5000 CWs technics have substituted for the traditional secondary or advanced ...

  • Diatoms as bioindicators of pollution in the Mantaro River, Central Andes, Peru

    Semi-quantitative analysis of two algal samples from the Mantaro River taken few kilometres downstream from La Oroya city at Junin, Peru, contained both organic-pollution tolerant and morphologically abnormal diatom associations. The organic pollution is inferred by elevated percentages of Nitzschia palea, Gomphonema parvulum and the Achnanthidium minutissimum complex; the total assemblage ...

  • Automatic control of pollutant on a shallow river using surface water systems: application to the Ebro River

    In this paper, the problem of automatic control of pollutant on a shallow river using surface water systems is addressed using a benchmark test case based in the Ebro River. The Ebro River presents flooding episodes in the city of Zaragoza in Spring when snow melts in the Pyrenees. To avoid flooding and high pollutant levels in living areas, some lands outside the city are prepared to be ...

  • Revealing the relationship between microbial community structure in natural biofilms and the pollution level in urban rivers: a case study in the Qinhuai River basin, Yangtze River Delta

    River pollution is one of the most challenging environmental issues, but the effect of river pollution levels on the biofilm communities has not been well-studied. Spatial and temporal distribution characteristics of environmental parameters and the biofilm communities were investigated in the Qinhuai River basin, Nanjing, China. Water samples were grouped into three clusters reflecting their ...

  • Water Pollution

    Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in ...

  • Monitoring micropollutants in the Swist river basin

    Micropollutant pathways were studied for the Swist river basin (Western Germany). The aim was to verify the effectiveness of a monitoring approach to detect micropollutants entering the river. In a separate sewer system, water was frequently found to be contaminated with micropollutants. Improper connections of sewage canals to the stormwater network seemed to be the cause of pollution. ...
