On December 29, 1998, everything changed for four-year-old Jarrett McElheney.
The toddler lived with his parents at the Oakwood Mobile Home Park, in Athens, Georgia, across the street from Southeast Terminals, a tank farm for storage of petroleum products. When he showed signs of illness and sluggishness, his parents brought him to a pediatrician, who reported that his blood chemistry indicated leukemia.1
