Verbrennungsstätte am Ganges bei Varanasi

Indiens heiligster Fluss gilt als Verkörperung einer Flussgöttin und wird oft auch so genannt wie sie: Mutter Ganga. Wer darin badet, so glauben Hindus, wird spirituell gereinigt. Für viele Menschen ist der Ganges zudem die einzige Trinkwasserquelle, meist ohne jede Filterung. Dabei ist dieser Fluss einer der am stärksten verschmutzten der Welt. Expertinnen und Experten der Physikalisch-Technischen Bundesanstalt (PTB) engagieren sich in einem Kooperationsprojekt mit indischen Partnerinstitutionen für die verlässliche Messung der Wasserqualität am Ganges.
