In Kamnik, Slovenia, the utility company Komunalno podjetje Kamnik issued a mandatory boil water notice for Iverje, Kamniška Bistrica, Palovče, and Velika Lašna. The measure was prompted by the presence of the microbiological indicator intestinal enterococcus in the Iverje catchment area. Authorities recommended boiling water for three minutes to protect individuals with weakened immune systems while disinfection procedures, including chlorination, were initiated. In the Barilović Municipality of Croatia, a public health notice was issued for the Šćulac and Siča areas.
