A nationwide jurisdictional analysis of drinking water frameworks was conducted to identify the political backdrop for the integration of the EWBS. Canada demonstrates no consistency in drinking water regulations and policies for EWBS application. While it is not possible for all specific contaminants to be monitored, the EWBS has the potential to effectively detect classes of contaminants applicable nationwide. A case study site was investigated for potential use of the EWBS. The general finding indicated that, despite having an advanced plant, unpredicted spills from upstream industries will continue to represent potential hazards for Walpole Island First Nation. Copper was identified as a contaminant of concern for the study site and was applied in behavioural bioassays using Daphnia magna. Three responses were examined upon exposure to varying concentrations of copper and results indicated change in swimming height as the most sensitive response for utility in an EWBS, followed by immobility.

The overall goal of this case study is to describe the history and present methods that the Philadelphia Water Department (PWD) uses to address its on-going earthy and musty drinking water T&O problems. The Philadelphia Water Department has developed a baseline for its water's aesthetic qualities since the early 1980’s. Philadelphia feels it has sufficient resources to control taste and odour problems. However, when directly asked, only 61–64% of the consumers are satisfied with the taste and odour of Philadelphia's drinking waters. A taste and odour early warning system is being developed for the two drinking water sources, the Delaware and Schuylkill rivers. Secondly, routine T&O panels and chemical analysis of geosmin and MIB are completed. Since the year 2000, 10 ng/L has become an early warning wake-up call for PWD. When higher levels are observed, testing is a priority, the source of the T&O is investigated and consumer complaints are monitored carefully. Present water treatment plants are conventional with chlorine disinfection, coagulation/sedimentation, rapid dual media filtration and final chloramination. The PWD uses powdered activated carbon, river water bypass and hydraulic changes in the distribution system to minimise odour events.

The article explores the political effects of popular consultations as a means of direct democracy in struggles over mining. Building on concepts from participatory and materialist democracy theory, it shows the transformative potentials of processes of direct democracy towards democratization and emancipation under, and beyond, capitalist and liberal democratic conditions. Empirically the analysis is based on a case study on the protests against the La Colosa gold mining project in Colombia. The analysis reveals that although processes of direct democracy in conflicts over mining cannot transform existing class inequalities and social power relations fundamentally, they can nevertheless alter elements thereof. These are for example the relationship between local and national governments, changes of the political agenda of mining and the opening of new spaces for political participation, where previously there were none. It is here where it’s emancipatory potential can be found.

Akin to the previous, 2014 event, with no data on voter ethnicity, no exit polls, and few post-election analyses, the 2018 Fiji election results remain something of a mystery despite the fact that there had been a significant swing in voting in favour of Opposition political parties. There have been several studies about the election results, but most of them have been done without much quantitative analyses. This study examines voting patterns of Fiji’s 2018 election by provinces, and rural-urban localities, as well as by candidates, and also compares the 2018 and 2014 elections by spending a substantial time classifying officially released data by polling stations and individual candidates. Some of the data are then further aggregated according to the political parties to which those candidates belonged. The current electoral system in Fiji is a version of a proportional system, but its use is rare and this study will provide an interesting case study of the Open List Proportional System. At the end of the analyses, this study considers possible reasons for the swing in favour of the Opposition.

Beginning in the early 1970s, Jewish and Muslim feminists, tackled “oral law”—Mishna and Talmud, in Judaism, and the parallel Hadith and Fiqh in Islam, and several analogous methodologies were devised. A parallel case study of maintenance and rebellion of wives —mezonoteha, moredet al ba?ala; nafaqa al-mar?a and nush?z—in classical Jewish and Islamic oral law demonstrates similarities in content and discourse. Differences between the two, however, were found in the application of oral law to daily life, as reflected in “responsa”—piskei halacha and fatwas. In modern times, as the state became more involved in regulating maintenance and disobedience, and Jewish law was backed for the first time in history by a state, state policy and implementation were influenced by the political system and socioeconomic circumstances of the country. Despite their similar origin in oral law, maintenance and rebellion have divergent relevance to modern Jews and Muslims.
