Two rural spring drinking water supplies were studied for their enteric virus levels. In one, serving about 30 dwellings, the water was chlorinated before distribution; in the other, which served a dairy and six dwellings the water was not treated. Samples of treated (40 l) and untreated (20 l) water were taken under normal and heavy rainfall conditions over a six weeks period and concentrated by adsorption/elution and organic flocculation. Infectious enterovirus in concentrates was detected in liquid culture and enumerated by plaque assay, both in BGM cells, and concentrates were also analysed by RT-PCR. Viruses were found in both raw water supplies. Rural supplies need to be analysed for viruses as well as bacterial and protozoan pathogens if the full microbial hazard is to be determined.

In this study Natural organic matter (NOM) characteristics and variations of catchment samples (brooks and collector lakes) from Western Finland, and drinking water produced from the same catchment were examined. Seasonal and spatial NOM variations were followed by means of DOC and HPLC-SEC with UV and fluorescence detection. NOM decreased from drains to lakes by 35 to 75% and from drains to drinking water by 73 to 94%. Drains had a higher NOM content in summer and a lower NOM content in winter and spring. Lakes showed inverse patterns and had a higher NOM content in winter and spring and a lower NOM content in summer. HPLC-SEC separated 8 molecular weight fractions. In drains the HMW fractions represented up to 80% of the NOM, in lake waters HMW fractions accounted for 50 to 70% of the NOM. In drinking water IMW fractions dominated. Increased NOM in raw water during winter was associated with increased IMW fractions and the appearance of HMW fractions in drinking water, DOC increasing from 1.4 mg C/L in summer to 5.8 mg C/L in winter. SPH-Tryptophan correlated with the dissolved organic nitrogen and DOC of the samples. The drain affected by agriculture generally presented higher SPH-Tryptophan values than the unaffected drain.

The foundation of the Alliance of Community-Owned Water Services in Europe (ACOWAS-EU), established during the consultation period for the 2020 recast of the European Drinking Water Directive, has shone a new light on community-owned drinking water supplies (CoDWS). CoDWS are drinking water supplies that are administered, managed, and owned by the local community membership that each supply serves. This paper reviews the presence of CoDWS within the five founding regions of ACOWAS-EU—Austria, Denmark, Finland, Galicia in Spain, and Ireland—and the co-operative model structure that underpins the sector. Although the co-operative structure for CoDWS has been prominent since the mid-20th century (and sometimes even earlier), there is a dearth of research into the sector’s importance and existence in an international context. Through a detailed case study, the Irish CoDWS sector (known in Ireland as the group water scheme sector) is analysed in depth, in terms of both its evolution and the opportunities and challenges it faces today. Areas, such as water quality, biodiversity, education, and community-involvement are discussed in particular, providing key learnings that may also be of benefit to the other CoDWS sectors within ACOWAS-EU and further afield.

Harvard Medical School convened a meeting of biomedical and clinical experts on 5 March 2015 on the topic of “Rethinking the Response to Emerging Microbes: Vaccines and Therapeutics in the Ebola Era,” with the goals of discussing the lessons from the recent Ebola outbreak and using those lessons as a case study to aid preparations for future emerging infections. The speakers and audience discussed the special challenges in combatting an infectious agent that causes sporadic outbreaks in resource-poor countries. The meeting led to a call for improved basic medical care for all and continued support of basic discovery research to provide the foundation for preparedness for future outbreaks in addition to the targeted emergency response to outbreaks and targeted research programs against Ebola virus and other specific emerging pathogens.
