Veröffentlichung Implementation and evaluation of the water safety plan approach for buildings(2019) Rapp, Thomas; Rickert, Bettina; Schmidt, Isabelle; Schmoll, OliverThe World Health Organization promotes water safety plans (WSPs) - a risk-based management approach - for premise plumbing systems in buildings to prevent deterioration of drinking-water quality. Experience with the implementation of WSPs in buildings were gathered within a pilot project in Germany. The project included an evaluation of the feasibility and advantages of WSPs by all stakeholders who share responsibility in drinking-water safety. While the feasibility of the concept was demonstrated for all buildings, benefits reported by building operators varied. The more technical standards were complied with before implementing WSP, the less pronounced were the resulting improvements. In most cases, WSPs yielded an increased system knowledge and awareness for drinking-water quality issues. WSPs also led to improved operation of the premise plumbing system and provided benefits for surveillance authorities. A survey among the European Network of Drinking-Water Regulators on the existing legal framework regarding drinking-water safety in buildings exhibited that countries are aware of the need to manage risks in buildings' installations, but experience with WSP is rare. Based on the successful implementation and the positive effects of WSPs on drinking-water quality, we recommend the establishment of legal frameworks that require WSPs for priority buildings whilst accounting for differing conditions in buildings and countries.

In addition reference substances (Methyl tert-butyl ether, 1-butanol and hexanal) were investigated for their suitability to qualify the panels and the individual panellists. Methyl tert-butyl ether (MtBE) and 1-butanol proved to be suitable for this purpose, whereas hexanal showed a wide distribution of the individual odour threshold concentrations. Both possible testing options (unforced and forced choice) were performed and gave similar results. However, with respect to the qualification of the panellists and the data analysis the unforced choice procedure showed advantages. As human olfactory perception is used for the analysis, the reproducibility and the comparability between laboratories is of particular concern. For the pipe material the TON results of the different laboratories were in a range of ş1.5 dilutions based on a dilution factor of 2. This might be improved by taking the individual sensitivities of the panellists into account more strongly. Appropriate measures for the improvement of the test method appear to be the use of the proposed reference substances for the training of the panellists as well as the auditing and the selection of the panellists. The results of this round robin test are used in the revision process of the standard.Quelle: http://www.sciencedirect.comVeröffentlichung Wasserwirtschaft in Deutschland(Umweltbundesamt, 2017) Arle, Jens; Bartel, Hartmut; Baumgarten, Corinna; Bertram, Andreas; Blondzik, Katrin; Brandt, Simone; Brauer, Frank; Claussen, Ulrich; Damian, Hans-Peter; Dieter, Daniela; Ginzky, Harald; Grimm, Sabine; Helmecke, Manuela; Hofmeier, Katja; Hofmeier, Maximilian; Hülsmann, Wulff; Kirschbaum, Bernd; Knobloch, Tobias; Koppe, Katharina; Koschorreck, Jan; Krakau, Manuela; Leujak, Wera; Mathan, Cindy; Mohaupt, Volker; Naumann, Stephan; Pickl, Christina; Rapp, Thomas; Rechenberg, Jörg; Deutschland.
