The popular Waze smartphone navigation app recently introduced a new feature – a water pollution detector. The feature aims to tell users if the lake or river they pass by or intend on swimming in while hiking or camping across Israel, suffers from pollution. The feature is the brainchild of the app’s architects and Zalul Environmental Association, which is dedicated to the protection and preservation of Israel’s seas, rivers and lakes. WAZE users passing by a polluted waterway see a pop-up window on their smartphones’ screens, telling them it is polluted and naming the parties known to be responsible for the pollution.
