Linkage Model

Estuarine reservoirs are available for use in various water resource systems. In agriculture, supplying irrigation water that meets water quality standards is essential for food safety. This study focused on the Ganwol estuarine reservoir in the midwestern region of South Korea, which suffers from water quality deterioration problems. To explore the water quality improvement in an estuarine reservoir, it is essential to understand the characteristics of water quality changes in the reservoir following water pollution control management. Therefore, the purpose of this study is to evaluate the effects of water quality management on the estuarine reservoir, which is separated by levees, using the soil and water assessment tool (SWAT)-environmental fluid dynamics code (EFDC) linkage model. In this study, soil remediation by dredging the reservoir’s bottom soil and effluent control from public sewage treatment works were considered as the water management plans. The results of this study indicate that reducing the internal load of the reservoir increases internal resilience and reducing the external inflow load decreases the impact on the system. Hence, comprehensive measures are effective in improving water quality.

The Impact

The visual and odorous characteristics of the environment tend to be those which have the greatest impact upon the public's assessment of environmental quality. In many cases the public's perception of water quality may be based entirely on these aesthetic aspects of a water environment. Those responsible for the management of surface water quality recognise the need to apply a range of management strategies including a consideration of the public's perception of water quality and the impact of this upon their use of rivers and beaches for recreation and amenity. This paper reports upon the results from a recent investigation into the impact of sewage derived litter on perceived water and environmental quality.

Catchment water quality management plans are central to the Department of Water Affairs and Forestry's (DWAF) water quality management strategy. Catchment plans provide a coherent framework to ensure that fitness for use is achieved at catchment level. This paper describes DWAF's perspective on and approach to key aspects associated with the development and implementation of catchment water quality management plans. It expands on the role and composition of a catchment water quality management plan; the guiding principles inherent to the development of a management plan; the key success factors ensuring implementability; key aspects associated with the development of the plan, public participation, project structure, water users and setting water quality objectives and various aspects in DWAF's approach for future consideration.

Chemistry Dynamics

We need to understand spatial variability in the mean concentrations and dynamics of riverine water quality for effective water quality management. Using river chemistry data for up to 578 locations across the Australian continent, we assessed the impact of climate zones on (i) interannual mean concentration and (ii) river chemistry dynamics as represented by constituent export regimes (ratio of the coefficients of variation of concentration and discharge) and export patterns (slope of the concentration-discharge relationship). We found that interannual mean concentrations vary significantly by climate zones. However, export regimes and patterns are generally consistent across climate zones. This suggests that intrinsic properties of individual constituents rather than catchment properties determine export regimes and patterns. The spatially consistent river chemistry dynamics highlights the potential to predict riverine water quality across the Australian continent, which will support national riverine water quality management.

The Impact

The general trend in water quality management has been to gather and use information on water quality variables for purposes of planning, design, and operation of water resources systems and wastewater treatment. However, the growing concern for environmental quality has given rise to a new trend in respect of the impact of water quality variables on human health and life conditions. Thus, there is the need for better understanding of how water quality processes evolve both in time and space under natural and man-made conditions. This accentuates the need for more efficient practices of monitoring to satisfy the objectives of water quality management plans. Upon this need, the adequacy of collected water quality data and the performance of existing monitoring networks have been seriously evaluated within the last decade. Problems observed in available data and shortcomings of current networks have led researchers to focus more critically on design procedures used. This paper examines the state-of-the-art in design of water quality monitoring networks. Available design procedures are discussed with respect to three basic features of a network: selection of sampling sites, sampling frequencies, and variables to be sampled. In conclusion, recommendations are presented for improvement of current approaches to the design problem.

Receiving Water

The design of efficient technical measures for the abatement of water pollution requires that wastewater discharge regulations are driven by receiving water objectives. However, such integrated water quality management is only possible when the impact to the aquatic ecosystem can be predicted quantitatively by means of integrated wastewater models. Typically, only a few types of wastewater discharge impacts are relevant for the state of the receiving water and, consequently, the structure of the model can be kept relatively simple when focusing on one of these impacts. The procedure of problem-oriented model selection is illustrated for three typical examples of acute water pollution, that is toxicity from un-ionized ammonia, hygienic hazard from pathogenic micro-organisms and oxygen depletion.

The Impact

The impact of modernization in the industrial sector has the potential to produce waste as residual products that can pollute the environment, damage and / or endanger health and the environment. Actualization of these threats is contrary to the ecologically Sustainable Development Principle which requires preservation of functions and controlling environmental pollution and damage. The disposal of waste from the production of krupuk Home Industry in Kenanga Village, Sindang Subdistrict, is channeled into a river which is a source of water for the community, causing river pollution. This research is a normative juridical research, based on normative analysis, legal science approach. Primary data as the main data is obtained from various legal materials related to research, supported also by secondary and tertiary data as additional data. The results showed that the implementation of Indramayu Regency Regional Regulation Number 9 of 2012 concerning Water Quality Management and Water Pollution Control, has not been implemented properly. This is evident from the existence of river pollution which is the source of water in Kenanga Village, Sindang Subdistrict, Indramayu Regency, which can no longer be used for people's daily lives due to the waste of krupuk production. The legal responsibility of cracker producers in the management of production waste as stipulated in Article 28 of Indramayu Regency Regulation Number 9 of 2012 concerning Water Quality Management and Water Pollution Control, which is subject to administrative sanctions in the form of a written warning, is deemed not to have a deterrent effect
