Geoinformation and clean water

What is the condition of a water course at a particular location? Where are watercourses in insufficient ecomorphological condition? How high is the concentration of pollutants in groundwater or in watercourses at a particular measuring point? Geoinformation also provides valuable information in the field of water availability and sustainable water management.

Potential exceedance of the reference value of radon concentration in buildings? Radon map (FOPH)

Radon is a naturally occurring, radioactive noble gas, which can seep into buildings through the ground. Switzerland is particularly affected by this problem due to its geology. The radon map indicates the probability (in %) of exceeding the reference value of the radon concentration of 300 Bq/m3 in a building.
