The Department of Environment and Natural Resources (DENR) on Thursday announced that the Manila Bay was cleaner as fecal coliform levels dropped in early February. Environment Secretary Roy Cimatu said water samples taken last February 8 from 21 monitoring stations surrounding the Manila Bay had shown significantly lower fecal coliform levels. From the annual average of 7.16 million most probable number per 100 milliliters (mpn/100 ml) in 2020, the level has dropped to 4.87 million mpn/100 ml.
