    The turquoise color may indicate pollution.

    THE Department of Environment and Natural Resources (DENR) has ordered an investigation of hotels and establishments in the Manila Bay area after discoloration bay waters was observed last week.

    “We suspect that this sudden color change from the previous dark blue to turquoise blue is caused by the direct discharge of wastewater from the treatment plants of buildings and establishments in the vicinity,” Environment Secretary Roy Cimatu said in a statement.

    Cimatu tasked Benny Antiporda, DENR undersecretary for solid waste management and local government units concerns, to oversee the investigation.

    A team from the DENR over the weekend inspected the baywalk near the SM Mall of Asia and Outfall No. 3 in Pasay City to check their wastewater discharge.

    The Metropolitan Waterworks and Sewerage System-Regulatory Office assured the public that drinking water in Metro Manila is safe from COVID-19.

    “The water supply maintained in our distribution systems up to the customers’ taps has been disinfected with chlorine, as prescribed by the Philippine National Standard for Drinking Water set by the Department of Health. Our water is therefore free from bacteria and viruses (including the COVID-19 virus) and is safe for domestic consumption,” Patrick Ty, the agency’s chief regulator, said in a statement.

    Ty said that wastewater discharged from sewage and septage treatment plants into water bodies has also been disinfected with chlorine, in accordance with the DENR Water Quality Guidelines and General Effluent Standards.

    A technical brief on water, sanitation, hygiene and waste management for the COVID-19 virus released by the World Health Organization showed chlorine disinfection has been proven to inactivate the coronavirus.
