This paper reflects, from an industrialist's perspective, on 25 years' operation of the Water Pollution Act in The Netherlands. The Act empowers Water Boards to implement national policy on water quality. These Boards may be regarded as a model for cooperation between the general public and industry, two partners that are both polluters and sufferers from pollution. Oxygen-consuming and heavy metal pollutants are considered as examples of the significant improvements achieved over the past quarter century.

Waste Water Management

Many activities and the continuous disposal of waste water has resulted water pollution in Tukad Rangda. Tukad Rangda's water quality over the last five years (2012-2016) indicated experiencing contamination with decreasing water quality. The condition indicates the need of serious effort to maintain the water quality of Tukad Rangda. The purpose of this research is to know the perception and behavior of head of household and businesses in conducting waste water management that potentially causing Tukad Rangda water contamination, determining water quality and water quality status based on the Pollution Index, and determining appropriate alternative strategies to control water pollution in Tukad Rangda. Sample was collected by purposive sampling. Water samples was taken at three point: on the upstream, middle, and downstream of Tukad Rangda. Samples are analyzed in situ and in laboratory. Determination of perception and community behavior based on questionnaires and interviews to households and businesses. The data obtained were analyzed by force-field analysis to determine alternative strategy of Tukad Rangda water contamination control. The results of perception analysis of households and businesses on waste water management that has the potential to cause Tukad Rangda water contamination shows well-categorized results. However, for the behavior of head of households and businesses on waste water management that potentially causing Tukad Rangda water pollution, each of them showing results that can be categorized as quite good and less good respectively. Water quality of Tukad Rangda at upstream, middle, and downstream areas have exceeded the water quality standard class II in accordance with the Bali Governor Regulations No. 16 year 2016 for these parameters: BOD, COD, phosphate, and lead. Water quality status of Tukad Rangda based on Method of Pollution Index at upstream, middle, and downstream classified slightly contaminated. Based on force-field analysis, the alternative strategy obtained is increasing the insight and understanding about waste water management to the community, water waste management regulation at household scale, coaching, supervision, and law enforcement against businesses violating the applicable regulations, providing waste water treatment facilities, as well as the development of Tukad Rangda as water tourism area through the involvement of community participation.

Abstract Experiments were carried out by treating the waste samples with electrocoagulation technology. This is done to determine the effectiveness of the removal of the electrocoagulation device against textile waste. The sample used is a synthetic sample with a concentration of 1091 mg/L Pt-Co units. The research was conducted twice with the first experiment being conducted to determine the most effective electrical voltage to remove the existing COD and color pollutants while the second experiment was conducted to determine the type of anode and cathode that was most effective in removing COD, Color, and heavy metal pollutants. In the first experiment, it was found that the electric voltage that could produce the best removal was 4 amperes and in the second experiment, the anode-cathode type with the highest % removal was Fe-Fe with % COD removal of 64.09639% and % color removal of 60.00619%. It was concluded that electrocoagulation method could effectively remove color and COD in waste water.

Municipal fragmentation is a real historical issue in Italy but its relevance has been differently perceived over time. With a focus on the municipal unions and amalgamations as the main tools for defragmentation, we will present an overview of the last quarter century (1990–2017) of territorial policy at the local level. The reforms introduced since 2010 marked a step change in this area: in fact, empirical evidence shows that the most recent defragmentation attempts have had a certain success. This article, by maintaining a descriptive approach, will try to answer why the most recent defragmentation policy achieved some results, in contrast to those of the past. Some explanatory factors will be presented by reviewing the stances of the main actors in this policy field and their interaction with national policy-maker goals and approaches as well as with normative elements and external conditions.

AbstractThis paper starts out with a theoretical argument, based on panel data, that public mood in general and societal pessimism in particular should be measured from an explicitly temporal perspective. Next, based on a survey among more than 200 Japanese students and a wide array of existing (longitudinal) data sources in three different languages and covering several decades it is shown that public mood in three quite different countries – first and foremost Japan, but also the United States and The Netherlands – is quite apprehensive. In all these three countries societal pessimism can be observed during the past quarter century. Finally, utilizing a MDSD approach a few possible tentative explanations for this observed pessimism are sought.

Waste Water Management

In Austria approximately 70% of the population is connected to sewerage and to biological waste water treatment plants. Whereas the urban areas are already provided with these facilities to a very high extent, effort is still needed in rural areas to meet the requirements of the Austrian legislation. The way, this task should be solved has provoked much controversy. It is mainly the question, whether centralised or decentralised sewage disposal systems are preferable from the ecological and economical point of view, that became a political issue during the last 5 years. The Institute for Water Quality and Waste Management was asked to elaborate a waste water management concept for the Lainsitz River Basin, a mainly rural area in the north of Austria discharging to the Elbe river. Both ecological and economical aspects should be considered. This paper presents the methodology that was applied and the criteria which were decisive for the selection of the final solution.

Medical Waste Management

Background:Poor medical waste management has been implicated in an increase in the number of epidemics and waste-related diseases in the past years. South Africa is resource-constrained in the management of medical waste.Objectives:A review of studies regarding medical waste management in South Africa in the past decade was undertaken to explore the practices of medical waste management and the challenges being faced by stakeholders.Method:Published articles, South African government documents, reports of hospital surveys, unpublished theses and dissertations were consulted, analysed and synthesised. The studies employed quantitative, qualitative and mixed research methods and documented comparable results from all provinces.Results:The absence of a national policy to guide the medical waste management practice in the provinces was identified as the principal problem. Poor practices were reported across the country from the point of medical waste generation to disposal, as well as non-enforcement of guidelines in the provinces where they exit. The authorized disposal sites nationally are currently unable to cope with the enormous amount of the medical waste being generated and illegal dumping of the waste in unapproved sites have been reported. The challenges range from lack of adequate facilities for temporary storage of waste to final disposal.Conclusion:These challenges must be addressed and the practices corrected to forestall the adverse effects of poorly managed medical waste on the country. There is a need to develop a medical waste policy to assist in the management of such waste.
