Domestic wastewater . Domestic effluents are generated from activities such as bathing, laundry, cleaning, cooking, washing, and other kitchen activities. This contains a large amount of organic waste with suspended solids and coliforms. Calculations made based on available data show that half the organic waste is from the domestic sector (PEM, 2003). As stated in the EMB report, domestic wastewater discharges contribute highest to the BOD load as the lack of sewage treatment system allows more than 90 percent of inadequately treated domestic sewage to be discharged into surface waters, which contain bacteria and viruses that threaten human life. Geographically, data show that one-third (30 percent) of BOD generation comes from Metro Manila and Region IV alone, at 18 and 15 percent, respectively (PEM, 2003). Industrial wastewater . Reports show that the volume and characteristics of industrial effluents vary by type of industry and are influenced by different factors such as production processes and the scale of production used.

Environmental Impact Management System . An on-going innovation under the EIS system is the introduction of programmatic compliance. Under this program, industries sited in declared industrial development areas may be issued a single Environmental Compliance Certificate (ECC). This approach has the advantage of reducing the cost of document preparation and review. Furthermore, it justifies the future application of carrying capacity assessments to determine the number and types of industries that should be allowed to locate in a given area.

The survey from Nov. 30 to Dec. 3 covered 1,200 randomly chosen adult respondents divided into samples of 300 each in Metro Manila, Luzon, Visayas and Mindanao. We wanted to see how Filipinos perceive the problem because it is very hard to push for the implementation of environmental laws if the public accepts water pollution as an unavoidable consequence of economic development, said Beau Baconguis, Greenpeace Southeast Asia campaigner in a press conference Friday. Half of the respondents said water pollution in the country was a very serious problem and posed great danger to their health and environment; 22 percent found it somewhat serious; nine percent, a little serious; and 19 percent, hardly serious. While growing concern for water pollution was noted among residents in urban areas, with 58 percent finding it unacceptable that economic progress should mean environmental destruction, some 48 percent said they were not aware of any laws enacted to help prevent pollution. Among the environmental policies cited in the survey were the Clean Water Act and the Solid Waste Management Act. Out of the 1,200 respondents, 26 percent said they were familiar with the Clean Water Act; 27 percent were aware of the Solid Waste Management Act while 50 percent admitted not knowing about the laws.
