Three completely mixed stabilization ponds are connected in series, and the system removes 99.998% from the total coliform count of the influent to the first pond. In stabilization ponds, coliform bacteria are removed by a first-order process (k= 3 d^-1). The last two ponds are identical and have a detention time of 7 days each one. Find the detention time of the first pond
