Calculate the rate (kg/day) at which permanganate must be added to a pump-and-treat system, where groundwater containing naphthalene (20 mg/L), phenanthrene (8 mg/L), and pyrene (0.2 mg/L) is pumped at 50 gpm and reinjected into injection well at the same rate after treatment in a reactor with sufficient residence time to completely mineralize the pollutants
