The Bureau of Fisheries and Aquatic Resources (BFAR) on Wednesday said it has observed significant improvement in the dissolved oxygen and water transparency of Taal Lake, nearly a month after the reported sulfur upwelling in the area. BFAR Director Asis Perez, citing reports from BFAR-4A regional office, said “the water quality in the lake which has been affected by the recent sulfur upwelling is now getting back to normal,” said Perez. According to the report, two of four barangays in Talisay, Batangas that were affected by the recent fish mortality have already fully recovered from sulfur contamination.
