ILOILO CITY: The Department of Environment and Natural Resources office here reiterated its advisory against swimming in Iloilo River. DENR Regional Director Jim Sampulna said that Ilonggo Senate President Franklin Drilon has given his office a six-month ultimatum to clean the river of fecal coliform concentration and other debris starting March to September this year. However, Sampulna said the main problem lies on the presence of several households along the river and its tributaries which is beyond the control of the DENR. Sampulna said that Resolution No. 2014-01 of the Iloilo-Batiano River Development Council is now being implemented by adopting Oplan Sustainable Workplan for Iloilo River Management (SWIM) as a program for the improvement of Iloilo River and its tributaries Dungon and Calajunan creeks in Iloilo City. A total of 12 watch stations were established along the 15-kilometer river in this city and it was noted that the fecal coliform concentration decreased during the summer season. Other watch stations are at the Quirino Bidge, Forbes Bridge, Sooc Bridge, Dungon mouth of the river, upstream Calajunan creek, Carpenter’s Bridge, Dungon Bridge, Calajunan downstream of dumpsite, Calajunan downstream of industries and Mambog creek.
