Most problems lead to groundwater, which represents more than 90 % of drinkable water in Slovenia. Big cities have outdated water systems, which are still regulated and regularly monitored.

But it’s estimated that 20 % of people aren’t connected to the public water supply and live around areas where agriculture is practiced intensively and is not regulated quite often.

Farming is a major contributor to water contamination. Fertilizers used in crop production seep into the soil and from there into the water where E. coli bacteria grows and contaminates.
