TEMPO Interactive, Surabaya:An official from the East Java governor’s office, Setia Purwaka, said the quality of the river water in Surabaya is undrinkable. The water quality standard has failed to qualify for category I, which is consumable. “The current condition is nowhere near that category,” Setia said following the launch of ‘Stop Surabaya River Pollution’ program at Jasa Tirta I company in Surabaya yesterday.
One examples, he said, can be seen from the biological oxygen demand (BOD) content in the water. In potable water, the BOD level should not exceed 2 milligram per liter. However, the BOD level in Surabaya rivers has reached 5 milligram per liter.
East Java Environmental Agency chief, Dewi Putriatni, said there are currently 50 – 60 big companies along the rivers of Gresik, Sidoarjo and on towards Surabaya. “Most of these companies do not have waste management facilities,” she said.
