THE PHYSICAL ENVIRONMENT


2.4.6.5
  Urban Environment

Air

The over-all air ambient level of the City is generally poor. As of September 1997, the Total Suspended Particulate (TSP) Concentration equaled an average of almost 800 ug/Nm3 as measured by the Environmental Management and Protected Area Sector (EMPAS) of the Department of Environment and Natural Resources, Region IX did not pass the National Ambient Air Quality Standards (NAAQS) of 300 micrograms per normal cubic meter (ug/Nm3).

The test for TSP was done in the City proper specifically on the following sampling locations: a) Police pcst at Tetuan Highway corner Tumaga Road; b) Jasmin Building, Buenavista St. corner Cancelar Road; and c) Don P. Lerenso St., near City Hall.

These are basically attributed to continuous and uncontrolled emission coming form the motor vehicles, and other existing major factory in the City. Data on sulfur dioxide (SO2) and nitrogen oxides (NOx) concentrations are not available due to unavailabiliuty of an air quality testing equipment.

 

Water

As of the second quarter of 1997, the condition of the major river systems including some of its tributaries are generally inferior. The DENR-EMPAS/Region IX revealed that the rivers of Manicahan, Cabaulay & Mercedes did not meet the DENR effluent/water quality standards as provided in the DENR Administrative Order Nos. 34 &35

The value for Total Suspended Solids (TSS) is high, while the value for Biochemical Oxygen Demad (BOD) is fast approaching the alarming stage especially in the urban area. The parameters mentioned are indicators for the pollution index of a water body. The BOD value for instance, in high concentration would mean that Coliform Organisms are high as well; these organisms will have detrimental effects on the health of the community.

In addition, it was noted that most of the beaches in the City did not pass the DENR effluent/water quality standards. On the other hand, other parameters such as dissolve oxygen (DO), pH and temperature passed the standards set by the DENR.

 

Solid Waste Management

One of the more serious problems that the country and not only Zamboanga City is encountering today is pollution due to the improper handling and disposal of solid wastes. This problem occurs not only in urban areas where population density is high and human activities are continuous and intense but it is also felt in the regional and rural areas. Large percentage of these solid wastes normally comes from domestic sources and the rest come from industries. Not all solid waste generated are collected and properly disposed, only about 70% to 80% are collected and the balance is either left on the streets, dumped into storm drains, esteros, canals. Creeks and rivers. Others are burned, thereby creating air pollution, or recycled by scavengers. Residential wastes, which is about 505 of the total waste generated, constituted the single largest source of solid wastes.

 

Solid Waste Generation

It is estimated that around 350 to 450 cubic meters per day (m3/day) of solid wastes are generated by the City, out of this generated solid wastes; around 70% to 72% are collected every day. (Source: ZC Public Service Office)

 

Solid Waste Collection and Disposal

Based on the statistical record of ZC Public Service Office from October 1996 to January 1997, garbage collected and disposed of per month by the City Public Services averaged 8662 cubic meters while that of the Private is equal to 12,654 cubic meters. It is noticeable that the increasing amount of garbage collected every month indicates that waste generation has correspondingly increased.

 

Status of the Existing Dumpsite

In 1995, the City has identified its temporary dumpsite, which is located at Barangay Lumbangan and is about 10 kilometers from the City proper. The area, which is approximately 4.4 hectares, is located in a ravine.

During the recent inspection of the said dumpsite in October 1997, the Barangay Chairman disclosed that the area is the lone dumpsite in Zamboanga City. The fear of the community living in proximity to the area is the strong possibility of ground water contamination due to high infiltration rate of leachate as revealed by the results conducted by the Bureau of Soils in the Region. The alarming level of groundwater contamination is quite noticeable as revealed by the Barangay Chairman since there is an increase of Diarrhea and Gastro-Intestinal cases among the local residents of Barangay Lumbangan and nearby barangay since large percentage of their drinking water sources are coming from deep well.

Although, the area is suitable for its purpose based from the initial inspection conducted, the area must undergo a full blown Environmental Impact Assessment (EIA) if condition warrants, to determine the suitability of the current dumpsite to a more viable and modern final disposal site, say a sanitary landfill. For this reason, the assessment of the dumpsite must be on a sustainable development in order to maximize its potential uses, meaning,

The current and future solid waste generation of the City could be handled by the said dumpsite without causing imbalance in the overall ecosystem of the area. The Office of the Department of Environment & Natural Resources (DENR) could expound guidelines on this aspect in detail. For the moment, the City government is advised to do the following recommended actions to their present dumpsite in Brgy. Luimbangan: 1) improvement of its physical and operational systems, that would facilitate the protection from environmental deterioration and thereby minimizing the outflow of untreated leachate emissions through immediate funding of project study of the area (see project profile); 2) recommended to be one of the alternative sited for the development of sanitary landfill which is located in the east coast of Zamboanga City; 3) establishment of a Proper Operation & Management System such as but not limited to management of Private Contractors, Budgetary Improvement of LGU’s, Capacity Building for Project implementation and Institutional restructuring.

 

Existing Policies/Laws Related to Solid Waste Management

To overcome the problem of solid waste management, the members of the Sangguniang Panlungsod of the City of Zamboanga passed Ordinance 92-013, an ordinance prescribing guidelines to regulate the mode of operation of the City garbage collection system and imposing a fee in the disposal of garbage in the City of Zamboanga and providing penalties for violations of such. Also issued was Ordinance 93-016, an ordinance that aims to establish and regulate the use of the slaughterhouse and providing also for penalty in violating the said law.

 

Disposal Facilities

Zamboanga City is one of the very few cities in the Philippines that have sewerage system collection and disposal systems. The sewerage system consists of vitrified clay pipe collectors; two (2) pumping stations and an outfall pipe which discharges untreated sewage 200 meters offshore into the Basilan Strait. The collection system is undersized compared to the population of the City.

Outside the existing sewer areas, residences and establishments have septic tank with effluent overflows to open drains and/or drainage conduits, which ultimately discharges into the Basilan Strait. Although these are nominally restricted to storm water run-off, these drain systems receive substantial sanitary sewage and effluent septic tanks.

Flooding does not appear to be a serious problem, but existing drainage facilities are inadequate and floods of short duration do occur with most of the drainage occurring low lying areas. With sanitary sewage being discharged into the storm drains, serious health hazards result from conditions conducive to breeding mosquitoes and propagation of water borne diseases.

Since the gradient of many areas drains into the low-lying sections of the City. The conduits and channels are often plugged with soil and debris adding to the polluted conditions. There is also a potential for polluted waters to percolate into the sub-soil contaminating the groundwater in the vicinity of these waterways.

 

Drainage Facilities

The City’s storm water drainage facilities consists of open drainage canals and concrete pipe culverts on both sides of the streets. This network of canals and culverts discharges wastewater and storm water and run-off to natural bodies of water within and around the area. Coming from the north and flowing eastward is the Tumaga River. In the west is the Baliwasan River; while in central area is the Sta. Maria River. Cutting through the core

Area is the Sucabon River, and west of Rio Hondo is a swampy area. All these serve as major receiving bodies for the storm water run-off of the area.

 

Sewerage System

The sewerage system consists of two pump stations and approximately 11.4 kilometers of vitrified clay collection pipes. The Sucabon Creek divides the sewer service area into East and West drainage basins. Wastewater produced in the East drainage basin is conveyed by gravity through the sewers to the east Pumping Station. Likewise, the West Pumping Station to the Basilan Strait for the final disposal is pumping wastewater collected at the West drainage basin.

 

Squatters & Slums

The overwhelming influx of migrants and rapid increase of population in the City causes the scarcity of human settlement. For this reason, they do not have any recourse but to reside in an area that could sustain one of the basic needs of man-shelter. At present, the identified areas where the squatter communities are situated are as follows: Canelar (Kabisayaan), Camino Nuevo, Sta. Barbara, CDCP Zone IV near Fort Pilar, Aplaya Rio Hondo and Sta. Catalina.

 

Cemeteries

The record of the Zamboanga City Social Welfare Services, list the following cemeteries in Zamboanga City:

 

1. Baliwasan San Jose Road                      16. San Roque Catholic Cemetery

2. San Roque Memorial Park, San Roque Cemetery  17. Forest Lake, Tumaga

3. Sta. Cruz, Veterans Avenue (Municipal)    18. Masa Cemetery, Upper Calarian

7. Tumaga (Protestant)                               22. Recodo (Muslim Cemetery)

8. Sta. Cruz (Chinese Cemetery)                 23. San Roque (Chinese Cemetery)  

9. Ayala                                                    24. Sinunuc Memorial Park 

10. Manicahan                                           25. Vitali 

11. Bolong                                                 26. Labuan

12. Mercedes                                             27. Sta. Cruz (Tetuan) Catholic

14. Curuan                                                 29. Cacao (Ecuminical)

15. Tagasilang

 

These cemeteries must be given appropriate attention to determine the locational viability and uses in relation to the nearby communities.

 

2.4.6.6    Environmentally Critical Areas

Environmentally Critical Areas (ECAs) are those areas with natural values so significant that, if at all, their development, utilization and/or conversion require great significant management control. Some ECAs may be natural while others may have been altered by certain human activities. Some ECAs will require preservation measures while others will require intensive management to restore or maintain their ecological values.

2.4.7  ENR Programs and Projects

As of 1997, Zamboanga City is implementing a number of environment and natural resources projects and activities. As part of its forest protection efforts, a total of five multi-sectoral forest protection committees are being organized and mobilized. In addition, one Barangay Bantay Gubat will be created.

IEC for a will be conducted focusing on forest fire prevention. Seeding production activities will also be undertaken through the production of some 540,000 seedlings and development of 80 hectares as part of the agro-forestry efforts.

Existing 25 ISF projects including devolved ones will be monitored while 265 CSC holders will be evaluated continuously.

Under soil conservation and watershed development, 2 watershed areas are being targeted for characterization and profiling. This is a preliminary activity prior to the proclamation of any watershed reservation. Activities are also being undertaken to identify and delineate area that are to be a part of the protected areas system.

Coastal clean up was introduced late 1996. Barangay Taluksangay, Manicahan and Margosatubig already conducted coastal clean-ups on November 14, November 30 and July 1996 respectively. Cleanups will be implemented as a regular activity for all CEP sites.

Community Based Mangrove Forest Management (CBMFM) in Western Mindanao covers a total area of 4,000 hectares, with 11 project sites, 8 of these were contracted by NGOs and 3 were already initiated by the administration.

Phase I (Resource Assessment and Social Preparation) and Phase II (Development Management) has been fully implemented. These include: Public Information Campaign (PIC) and Information, Education and Communication (IEC) Campaign, Community Organizing (CO), Value Orientation Training, Capability Building, Resource Inventory Comprehensive Socio-economic Profiling, Perimeter/Boundary Survey, Zonification of CBMFM Area, Six-Month Mangrove Rehabilitation and Preparation of a 25-year Mangrove Management Plan.
