An oncologist raised in the South Beaches developed cancer. She requested that water samples be measured in the area. In 2018 potable water distributed by the city of Melbourne measured up to 12 parts per trillion of PFBA (perfluorobutanoic acid). The EPA has established no standards for allowable levels of PFBA for drinking water. Minnesota has established a guideline of 7,000 parts per trillion. The measurements were well below this level. Critics thought that Minnesota standards were too low. There was no explanation of why the substance was in the water. Potable water furnished by the Cocoa water department found none of the contaminants. A cancer cluster of 175 cases including 50 people under 40 were reported on social media in a Satellite Beach Facebook group called Satellite Beach Health and Hope for Tomorrow. Cancer clusters have been found before in the area.
