"Do you think I should explicitly mark as "drinking_water=no" the streams,
springs and pits known to be poisonous? They use to have a sign telling it." We are talking here about official public water collection points. In rivers and streams, the quality of water often changes a lot(from hour to hour). Temporarily she can be unfit to drink for humans and animals, so there is no point in giving such tags in such places, the more so when someone takes water from the river, he risks taking advantage of his experience. It will be another thing to drink clean, unrecognized cold water flowing out of the glacier, and something else to drink water from the river with a turbid water full of bacteria and tem.20 degrees. Often, if the town does not have access to clean water, or the quality of water can change quickly, it has a water treatment station that monitors the quality of drinking water used for drinking, washing, watering the garden, machines, spiritual ceremonies, etc. every day. Beyond civilized areas, we need to be more careful. Regards Slavo
