Minister of Internal Affairs of Ukraine Arsen Avakov believes that Ukraine must not supply water to the temporarily occupied Crimea until the country restores its sovereignty over the peninsula. Until 2014, Ukraine provided 85% of Crimea's fresh water needs through the North Crimean Canal which connects the Dnieper with the peninsula. After Russia had occupied Crimea, water supplies to Crimea were cut off. Currently, water reserves on the peninsula are replenished from reservoirs and underground sources. According to Crimean environmentalists, regular use of underground sources leads to salinization of soil.
