Mexico City residents fear 'serious health problems'

Mexico City's army and government authorities assist residents affected by an oily substance in their tap water by providing water jugs and water purification systems.
Residents fear the problem could escalate into a 'very serious problem' for their health. This is part of an emergency plan across the capital following a March 31 streport in the Benito Juarez neighbourhood, where residents complained about the water in their homes.
