“…This situation is more serious in developing countries owing to rapid industrialization and urbanization ( Su et al, 2011) . In China, 45% of river water was unsuitable for drinking, and 21% didn't meet agricultural standards by monitoring data of more than 400 river sections in 2008 ( Jiang, Jin, and Lin, 2011) . Accordingly, it is essential to protect and improve river systems, which necessitates understanding the role of contaminants and a greater focus on how groups of organisms and ecological functions respond to pollution stress ( Jennerjahn, 2012) .…”

Li, J. L.; Lin, S. Y., and Song, Q., 2016. Characteristics of sediment bacterial community in response to environmental impacts in a sewage polluted river. In : Harff, J. and Zhang, H. ( eds. ) , Environmental Processes and the Natural and Anthropogenic Forcing in the Bohai Sea, Eastern Asia. Journal of Coastal Research, Special Issue, No. 74, , ISSN 0749-0208.The Jiaolai River is the main source of industrial and irrigation water for its catchment of 3900 km 2 . Anthropogenic activities have caused heavy pollution of this river, but their impacts on biota have never been evaluated. In this study,molecular techniques were applied to investigate the impacts of environmental pollution on the river. Quantitative PCR revealed that total bacterial abundance ranged from 2． 90×10 7 to 2． 12×10 8 copies / g, with no significant differences among sampling sites or seasons. Bacterial abundance and pore water ammonium concentration were negatively correlated. Cluster analysis revealed that bacterial communities were mainly distributed into groups corresponding to nitrate concentration. Two clone libraries were constructed to compare the bacterial composition of samples with high ( J308) and moderate ( J304) nitrate impact. Sample J308 was characterized by more members in Clostridia and disappearance of Betaproteobacteria members, which are the primary contributors to nitrogen biogeochemical cycling. Bacterial communities in the sediment were clearly differentiated by environmental nitrogen pollution, suggesting that nitrogen eutrophication was the main environmental problem influencing the Jiaolai River.

“…The growing level of pollution and economic growth in the past decades have imposed increasing threat to the drinking water sources worldwide (USEPA 2002(USEPA , 2006World Bank 2009;Jiang et al 2011), which necessitates a rapid conversion of watershed modeling into sound management practices (Kho et al 2009;Meng 2009). The science-based protection of drinking water focuses on identifying various sources of pollution (Canale and Effler 1989;Trauth and Xanthopoulos 1997;Edwards and Withers 2008;Karbassi et al 2011).…”

Nonpoint source pollution generated by agricultural production and city construction has been studied for decades, but very few researches have been conducted on the regional assessment of nonpoint source pollution in the acid rain regions, particularly relating to the control of pollutant in the drinking water source areas. In this study, an integrated framework was applied to estimate nitrogen and phosphorous load in a typical acid rain influenced reservoir, China. The method comprised three separate steps: (1) a watershed model-soil and water assessment tools-was used to estimate nitrogen and phosphorous load from the upper stream watershed; (2) collection of acid rain samples, together with a GIS-based calculation to estimate the atmospheric deposition flux; (3) introduction of a simple export coefficient method. The case study indicated atmospheric deposition accounted for 56.75 % of total nitrogen load during the year, with the highest level of deposition load taking place during the wet season. Maximum phosphorous (93.37 %) was linked to the upstream runoff, originating from the upper watershed. Further analysis by watershed model and export coefficient method indicated forest exported most total nitrogen (27.72 %) and total phosphorous (58.78 %) in the upstream watershed. Results indicated that in the region influenced by acid rain, the nitrogen management should encompass the management of land use practices and the control of acid rain in catchments feeding into drinking water storage areas. It could be inferred that NOX emissions might cause both globe warming and eutrophication in the drinking water sources. This paper could provide a basis for water quality management in such regions.

“…Moreover, monitoring is expensive and voluntary compliance is poor. Many regulatory and economic options exist to address the problems; however, the constraints like low institutional capacities, social pressure, political will, and inadequate financial resources cannot be ignored (Jiang et al 2011;Carr and Neary 2008).…”

Water Pollution and Abatement Policy in India

During the last 50 years or more, increasing population, industrialization, and agricultural development have profoundly impacted on natural ecosystems and water quality (Khan and Hanjra 2009;Park et al. 2010).Water resources are coming under intense pressure in Asia. The Asia Pacific region has the highest annual water withdrawal and return flows among the world's regions due to its geographic size, population, and extensive and intensive irrigation practices. More than half of global irrigation is taking place in Asia and results in a high level of agrochemical consumption, which is nonpoint source pollution. Another form of nonpoint source pollution comes from the topography of the region, resulting in high sediment loads (Evans et al. 2012).The domestic pollution problems are a factor not only of the wastewater generated but also of inadequate treatment and management measures. The volume of wastewater generated annually across Asia is nearly 144 km 3 , of which 37 % is generated in China, 27 % in South Asia, 20 % in Japan, 6 % in Southeast Asia, and 3 % in Central Asia (AQUASTAT 2011; Evans et al. 2012). Only an estimated 33-35 % of all wastewater in Asia is treated, with the lowest treatment rates in South Asia (7 %) and Southeast Asia (14 %) (Table 2.1).Increasing water pollution from accelerating domestic, industrial, and agricultural activities is a major issue for nearly all Asian developing countries. Table 2.2 gives an overview of the level of BOD pollutions among the developing countries in Asia. China, as the largest economy among the regions observed, reported the most pollution, at 8.82 million kg/day in 2006, eclipsing BOD emissions from the other regions. This is compared to a combined total BOD emission of 1.96 million kg/day from Indonesia, Thailand, and Vietnam, the major polluting countries in the Southeast Asian region. These levels were not surprising when viewed in context of the countries' GDP, as in 2006, China's GDP was about 4.6 times of that of the three countries combined.
