Nakeyja Cade bathes her three children in boiled bottled water after her one-year-old daughter Zariyah Cade (center left) had a blood test scoring high in lead content in Flint, MI on March 1, 2016. The working single mother of three says Zariyah started having seizures months after she was born and believes that the lead in the water is responsible. Her 3-yr-old son was tested and his levels are not as high. She has yet to test her 50year-old daughter and herself. After trying three different water filters, water in the house is testing high for lead. The City of Flint, through a series of maneuvers, went from using drinking water from Detroit to water from the Flint river. The Flint river water has now been shown to contain trihalomethanes, a chlorine byproduct linked to cancer and other diseases. A study by the Hurley Medical Center stated the proportion of infants and children had an extremely above-average levels of lead in their blood which had nearly doubled since the city switched its water source.
