KAN proficiency testing program on the bottled drinking water conducted on 2004 was participated by 46 testing laboratories. Participant laboratories were asked to test the sample for nitrat, nitrit, ammonium, sulphate Cl, Cn, F, F, Fe, Mn, Pb, Cu, Cd, As and Hg contents. Proficiency testing sample were prepared by provider, which also conduct homogeinity test for the Hg and Cu contents of the sample. As the sample was judged to be homogen, they sent to participant laboratory in 2 packs identified as sample KAN A and KAN B. Laboratory testing results were analyzed by statistical method, started on homogeinity of data, Dixon test and Z-score. The evaluation results shows that only sulphate, Cl, F, Fe and Cu contents could be analyzed among the other 14 parameters, which is could not be evaluated because of the in homogeinity of data provided by the laboratories. The inhomogeinity of data was caused by insufficiency of laboratory’s personnel and equipments. The evaluation of proficiency testing results for sulphate, Cl, F, Fe and Cu contents show only 1 satisfactory result among 5 accredited participants, and 9 satisfactory results among 39 non-accredited participants. The conclusion is based on the Z-score analysis of the evaluated parameters.

AbstractThe United Nations General Assembly explicitly recognized the human right to water and sanitation and acknowledged that drinking water is essential to the realization of all human rights in a 2010 resolution. Supporting and strengthening the quality infrastructure in countries throughout the world guarantees more reliable water quality analyses, thus reducing the risks to consumers’ health. The present paper describes a multilateral cooperation project developed in Nicaragua to improve the country's quality infrastructure and, in turn, the quality control of drinking water. The project was developed with the support of National Metrology Institutes (NMIs) from the Inter-American Metrology System (SIM), the Physikalisch Technische Bundesanstalt (PTB) and the participation of research institutes and laboratories in Nicaragua. Several mechanisms such as awareness seminars, workshops, metrological screenings, peer review of the laboratories’ quality systems, and organizing proficiency testing (PT) were used to successfully achieve the cooperation goal. As a result, technical infrastructure for the organization of PT rounds in Nicaragua was implemented to evaluate the relevant physicochemical parameters such as pH, chloride (Cl−), and nitrate (NO3−) in drinking water. The results from the PT rounds which took place during the two-year cooperation project showed substantial improvement in the performances of the participating laboratories, and therefore, in their measurement methods. Finally, this article shows how multilateral cooperation projects can strengthen the quality infrastructure, improving and ensuring the quality control of drinking water.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).
