Abstract: DEL MUNDO, JONALOU A. Assessment of the Environmental Impact of Commercial Piggery Waste Disposal in Selected Upland Municipalities of Cavite. Bachelor of Science in Environmental Science, Cavite State University, Indang, Cavite. April 2004. Adviser: Dr. Simeon S. Crucido. The environmental impact of piggery waste disposal in three upland municipalities of Cavite, namely, Indang, Silang and Alfonso was evaluated using survey questionnaires, actual farm visitation and laboratory analysis of water quality of nearby water systems. Sixteen (16) commercial hog farms were included in the study done from June-October 2003. Most of the farms surveyed were located away from residential areas but were adjacent to bodies of water such as rivers, streams, spring or creek. Lagoon system is predominantly used as waste disposal system followed by biogas digester and deposit ponds. Some farms still directly dispose piggery wastes into nearby creeks. Waste disposal systems of the piggery farms affect the quality of nearby bodies of water by lowering their Dissolved Oxygen (DO) content, increasing Chemical Oxygen Demand (COD) values, and contaminating the water with high amount of nitrate and phosphorus. T-tests comparing water quality of polluted and non-polluted bodies of water near the farms revealed inferiority of the polluted water source to non-polluted water in terms of COD, DO, ammonia, nitrate and phosphorus contents. Social and health impacts of the commercial hog farms to the community include the hazards posed by the odor and noise coming from the farm, disturbance in water supply and the undesirable health effects of improper dumping of piggery wastes in the river systems.

The environmental impact of piggery waste disposal in three upland municipalities of Cavite, namely, Indang, Silang and Alfonso was evaluated using survey questionnaires, actual farm visitation and laboratory analysis of water quality of nearby water systems. Sixteen (16) commercial hog farms were included in the study done from June-October 2003. Most of the farms surveyed were located away from residential areas but were adjacent to bodies of water such as rivers, streams, spring or creek. Lagoon system is predominantly used as waste disposal system followed by biogas digester and deposit ponds. Some farms still directly dispose piggery wastes into nearby creeks. Waste disposal systems of the piggery farms affect the quality of nearby bodies of water by lowering their Dissolved Oxygen (DO) content, increasing Chemical Oxygen
Demand (COD) values, and contaminating the water with high amount of nitrate and phosphorus. T-tests comparing water quality of polluted and non-polluted bodies of water near the farms revealed inferiority of the polluted water source to non-polluted water in terms of COD, DO, ammonia, nitrate and phosphorus contents.
Social and health impacts of the commercial hog farms to the community include the hazards posed by the odor and noise coming from the farm, disturbance in water supply and the undesirable health effects of improper dumping of piggery wastes in the river systems.
