‼ Well water can kill you: In Ukraine, a child died due to nitrate poisoning in drinking water, and every fifth sample tested from wells and other local sources contained an excess of nitrates. The state production and consumer service in 2026 recorded 9 cases of water-nitrate poisoning of children under the age of three. One case ended in death. In 21.4% of the water samples tested from wells and other non-central sources, excess nitrates were found. In tap water - 0.33%. Nitrates disrupt the blood's ability to carry oxygen. The greatest danger is to babies, especially if you make baby formula with such water. Even clear, odorless water can be dangerous. Nitrates cannot be determined by taste, and boiling does not remove them. Ukraine online.
