The South of Binh Duong province has undergone various economic activities and significantly contributed to the local budget, but has also posed adverse impacts on environment where the decrease in surface water quality is a vital of concern. To evaluate the change in surface water quality and carrying capacity of receiving water bodies in southern waterways of Binh Duong province (not mentioned in this work), the surface water quality data was recalled from 25 monitoring stations during 2012 – 2016 and sampled at 93 locations in the dry season of 2017. In the period of 2012 – 2016, the SWQ fluctuated from very poor to good level (WQI = 20 – 88). The sites of interest were the Chom Sao canal (RSG5), Bung Cu stream (RĐN2), and Thi Tinh river (RTT1) (WQI <7) with high concentrations of BOD5, COD, and coliform, etc. In the dry season of 2017, the SWQ was ranged from very poor to good level (WQI = 16 – 88). Some monitoring locations should be taken into consideration were STT2 in Thi Tinh River, MC25 in Cau Dinh stream, MC50 in Cat - Bung Biep stream, and MC91 in Cai stream due to high concentrations of SS, turbidity, NH4+-N, BOD5, COD, etc. Accordingly, it is necessary to continue studying and assessing the waste water generation, the carrying capacity of receiving water bodies in relation to the local socio-economic development plans, as a basic for local surface water management and the sustainable development.

Phosphorus is an essential component of modern agriculture. Long-term land application of phosphorous-enriched fertilizers and animal manure leads to phosphorus accumulation in soil that may become susceptible to mobilization via erosion, surface runoff and subsurface leaching. Globally, highly water-soluble phosphorus fertilizers used in agriculture have contributed to eutrophication and hypoxia in surface waters. This paper provides an overview of the literature relevant to the advances in phosphorous management strategies and surface water quality problems in the U.S. Over the past several decades, significant advances have been made to control phosphorus discharge into surface water bodies of the U.S. However, the current use of phosphorus remains inefficient at various stages of its life cycle, and phosphorus continues to remain a widespread problem in many water bodies, including the Gulf of Mexico and Lake Erie. In particular, the Midwestern Corn Belt region of the U.S. is a hotspot of phosphorous fertilization that has resulted in a net positive soil phosphorous balance. The runoff of phosphorous has resulted in dense blooms of toxic, odor-causing phytoplankton that deteriorate water quality. In the past, considerable attention was focused on improving the water quality of freshwater bodies and estuaries by reducing inputs of phosphorus alone. However, new research suggests that strategies controlling the two main nutrients, phosphorus and nitrogen, are more effective in the management of eutrophication. There is no specific solution to solving phosphorus pollution of water resources; however, sustainable management of phosphorus requires an integrated approach combining at least a reduction in consumption levels, source management, more specific regime-based nutrient criteria, routine soil fertility evaluation and recommendations, transport management, as well as the development of extensive phosphorus recovery and recycling programs.

The carrying capacity of receiving water bodies is one of the important data for water quality management, pollution source control towards harmonizing with the economic development and environment protection. Therefore, this research aimed atevaluating the carrying capacity of receiving water bodies in the south of Binh Duong province up to 2030. 06 key water quality indicators (COD, BOD, TSS, PO43--P, NO3--N, NH4+-N) were exmained with 02 wastewater treatment scenarios. Results showed the investigated area hardly had carrying capacity for NH4+-N and PO43--P, followed by TSS, BOD, and COD. In case of improving wastewater treatment status till 2030, the carrying capacity of receiving water bodies would be increased, but not significant. The carrying capacity of several basins needs to be paid special attention are: Suoi Con 1 basin (BOD, COD, NH4+-N), Suoi Cai basin (BOD, TSS and NH4+-N), the upstream of Cay Bang – Cau Dinh basin (BOD, COD, TSS, NH4+-N), the upstream of Chom Sao – Rach Bung basin (05 parameters, excepting NO3--N), the upstream of Binh Hoa – Vinh Binh basin (BOD, COD, PO43--P, NH4+-N). These findings are an important basis for formulating strategies and proposing measures for local pollution source control and surface water management.

The Given

Monitoring of surface water, through the analysis of physical-chemical and chemical parameters is a very important factor in the control of water quality and the health of living beings. Surface water quality is largely determined by the nature (atmospherics) and anthropogenic processes (discharge of municipal and industrial waste water). The results of monitoring of surface water are usually too expensive and difficult for correct interpreting, due to the spatial and temporal variations in water quality. By applying Multivariate statistical analysis can achieve significant reductions of the ampleness of the available data and the better interpretation of the obtained results about the quality and ecological status/potential of water. In this paper, were analyzed selected results of the analysis of surface water in AP Vojvodina in 2011 year by using multivariate statistical analysis (cluster analysis and principal components analysis). These techniques allow the interpretation of the results of the monitoring program of investigated surface water bodies and simultaneous identification of registered influence and potential sources of pollution on the quality of the given water bodies. With both methods applied and the division of water bodies tested in the same manner at the origin (natural and artificial) and on the basis of territorial belonging monitoring stations (Banat and Backa). Individual variations are discussed in corresponding differences in individual measuring stations in relation to others. Application of the given method, a grouping of the examined indicators of water quality in the following factors: hydro-chemical factor, ecological factor, the factor point pollution and diffusion. The obtained results confirm the initial hypothesis that the use of different statistical methods can identify the main factors that have an impact on the ecological status and ecological potential of water bodies and to improve the existing monitoring. In addition, analysis of the extracted surface water bodies where it is necessary to implement simultaneous monitoring of the biological quality elements to determine whether chemical parameters ensure the functioning of ecosystems.

Heavy Metal Content

Water samples of six sampling sites (two downstream, two abattoir sites and two upstream sites) were analyzed using standard methods to determined and assessed heavy metal content of abattoir effluent on surface water quality of River Katsina-Ala, Benue State, Nigeria for rainy and dry seasons. Rainy season heavy metals results were; Cr6+ (0.032+0.06mg/l); Mn2+ (0.16+0.034mg/l); Cu2+ (0.86 +0.46mg/l); Pb2+(0.006+0.002mg/;Cd2+(0.0023+0.004mg/l) and the dry season results were: Cr6+(0.028+0.007mg/l); Mn2+(0.07+0.05mg/l); Cu2+(0.85+0.16mg/l); Pb2+(0.0030+0.014mg/l); Cd2+(0.0021+0.012mg/). Most heavy metals for both seasons were within the maximum permissible limit set by Federal Ministry of Environment, Nigeria (1991). The mean concentrations of Zn2+(1.70+0.29 mg/l) for rainy season and Zn2+(1.33+0.23mg/l) dry season were above the control and standard safe limits of < 1mg/l FMEnv (1991) for surface water quality. There was no significance difference (p<0.05) between the means from upstream and downstream sites for both seasons; though significance difference (p<0.05) existed at the abattoir sites. River Katsina –ala is slightly polluted. Heavy metal content from effluents from abattoir contributed to upset the physicochemical balance of the river. Bioaccumulation and bio-magnification of heavy metals may occur from prolong usage of the river water for drinking. It is suggested that the abattoir effluent be treated before discharge into the river to reduce environmental and health hazards.

Water Pollution Index

Based on the structural analysis of complex hydrochemical indices for assessing surface water pollution used in various river basins, and the laws of limiting factors, a mathematical model was obtained in the form of the maximum permissible water pollution coefficient (Kпдзi), representing the product of the water content coefficient (Kb) and the maximum water pollution (Kпзi), by based on the laws of nature, principles and properties of natural processes in, together with the water pollution index (ИЗВ), are used for the geoecological assessment of the surface water quality of the Ile River basin on a spatial-temporal scale, taking into account the regulatory criteria for maximum permissible concentrations of pollutants for fishery water bodies, that between the coefficient of the maximum permissible water pollution (Kпдзi) and the water pollution index (ИЗВ) there is a pronounced relationship, described by a logarithmic equation, allowing them to be used to assess the ecological state water bodies. Water quality assessment was carried out for four hydrological sections of the Ile River catchment basin, which showed that water pollution is of a transboundary nature, since at the Dobyn hydrological station, located on the borders of the Republic of Kazakhstan and the People's Republic of China, the water quality is «polluted», and from the Kapshagai reservoir to Lake Balkhash «moderately polluted», where due to the selfcleaning ability of the aquatic ecosystem and the waters coming from the tributaries, there is some improvement in water quality.

The waterbodies of the Berlin region are intensively used for different purposes. High importance is given to the water supply to gain drinking water from groundwater and bank filtrate and for the recharge of groundwater. For these applications a good surface water quality would be an advantage, but the water bodies are loaded with treated sewage, stormwater and combined sewer overflow. This leads to quality problems in the water bodies, especially eutrophication, requiring scientifically based water quality targets for phosphorus. Measures for the reduction of eutrophication in rivers and lakes are presented in this paper, illustrating two different situations, that have been achieved through Berlin's efforts at reducing phosphorus loading.
