Erster Giardiasisausbruch im Zusammenhang mit kontaminiertem Trinkwasser in Deutschland

Worldwide, outbreaks of Giardiasis associated with drinking water have been reported since 1965. The present work describes for the first time an association between reported Giardiasis cases and the occurrence of the microorganisms in drinking water in Germany. After a small community reported a suspicious increase in the occurrence of Giardiasis an analysis of drinking water showed the presence of Giardia lamblia. Field survey and further microbiological analyses allowed to identify possible point sources of infection in the catchment area of the water source. Experience from other countries shows that there is a correlation between outbreaks of parasite-linked diseases associated with drinking water and an increased parasite contamination of source water combined with inadequacies of water treatment. In the currently described case it cannot be ruled out that a relative high parasite concentration in one of the used water wells, an insufficient protection of the water-catchment area, a missing filtration step of water treatment and an insufficient systematic microbiological monitoring of the used wells have caused the Giardiasis outbreak.     

Allgemein anerkannte Regeln der Technik und Legionellen im Trinkwasser

To investigate the association between the engineering standards of drinking water systems and the extent of the Legionella colonization, we subjected our 2006 published data of the drinking water monitoring of the city's public health services for Frankfurt on Main, Germany, to closer analysis. A total of 413 records were available, with both technical data and results of the Legionella colonization. When comparing the classes of technical deficiencies of the drinking water installations with the Legionella colonization results, 93% of the Legionella data "not dedectable in 100?ml" were found in the group of drinking water installations that were technically assessed as "free of deficiencies". Thus, "good" technical engineering is associated with low or lack of Legionella colonization with a high probability even with hints for a dose-effect phenomenon-the more engineering deficiencies that exist, the higher the Legionella contamination.

Gesundheitliche Anforderungen an Werkstoffe und Materialien im Kontakt mit Trinkwasser

In Germany the hygienic requirements on materials used to supply drinking water are a part of the technical standards. These regulations have to ensure that legal requirements on drinking water are met at the tap. The hygienic harmlessness is assured by requirements on the composition of materials and by test procedures including parametric limits. Historically, the requirements on different types of materials are a part of different technical standards.
