Thesis Title Cruz River System to improve its water quality in the Municipality of Nagcarlan, Laguna, Philippines For. Nguyen Van Hieu Supervisor (s) EMS II / SMO Laguna Focal Supervisor’s signature Abstract: San Diego River is an important tributary of the Sta. Cruz River System located in Nagcarlan, Laguna, Philippines. The river is one of the sources of water for the irrigation of rice fields in Nagcarlan and provides food and livelihood to its residents.
However, due to the large amount of wastes produced by the residential, commercial establishments and backyard farms, the water quality of the river continuously deteriorated. The Rehabilitation project of San Diego River is one of the Manila Bay Rehabilitation Plan which aims to identify the issues and concerns that hamper the improvement of the water quality of the river. This paper provides an overview of the current condition of the San Diego River. It focuses on the overall experience of the student as a trainee, and participation in the various activities of the project.
The implementation is a joint undertaking of the Manila Bay – Site Management Office-Laguna (SMO- Laguna) of the Provincial Environment and Natural Resources Office (PENRO) and Regional Office-IV-A under the Department of Environment and Natural Resources (DENR). The project is in collaboration with the Local Government ii Luan van Unit (LGU) of Nagcarlan, and the cooperation of the selected barangays. Moreover, this report will serve as a baseline towards the future river water restoration and rehabilitation in the Philippines.

Rationale Water is the most significant resource to mankind and our planet. The beneficial usage of water thus depends on its water quality, as contaminated water would lead to adverse environmental and health consequences.
Hence, rivers and other inland aquatic ecosystems are considered as the most essential natural resources which provide us with many valuable services such as public water supply, food production, and recreation purposes. However, anthropogenic and natural activities caused directly or indirectly by humans gradually alter the inland waters. Water pollution is also one of the major problems in most developing countries such as the Philippines. According to the Water Environment Partnership in Asia (undated), increased population, urbanization, agriculture and industrialization have raised concerns on the water quality of the country.
Moreover, many water bodies are now un-fit for their intended uses. In the Philippines out of 421 rivers, 50 are now considered by the Department of Environment and Natural Resources as “biologically dead”. It is therefore necessary to ascertain the quality of the river, evaluate its impacts and provide measures to mitigate the problems. (Mishra et al., 2009) Manila Bay, one of the most significant bodies of water in the Philippines has been faced with serious water quality issues primarily caused by human activities such as the unabated throwing of solid waste and continuous discharge of liquid waste to nearby water bodies, industrial effluents and leachate along the bay.
In January 1999, a group of concerned residents, led by UP Law student 5 Luan van filed an ambitious lawsuit in trial court that allegedly that the water of Manila Bay have high fecal coliform bacteria which is beyond the allowable threshold level that the water can no longer be fit for swimming. The Philippine Supreme Court rendered a decision on the case on December 18, 2008 a continuing mandamus ordering 13 government agencies to clean up, rehabilitate and preserve Manila Bay, restore and maintain its water quality to SB level to make them fit for swimming, skin-diving and other forms of recreational activities. With the Department of Environment and Natural Resources (DENR) as lead implementing agency, the implementation of the Operational Plan for the Manila Bay Coastal Strategy CY 2017-2022, using the Area-Based Management strategy was initiated. Manila Bay has a total area of 1,994 square kilometers with 190 kilometers coastline.
The bay area covers eight (8) provinces and 178 local government units in three regions of the country, namely National Capital Region (NCR) Region III, and Region IV-A. The On-the job training (OJT) of the student-trainee involved her in the initial implementation of the Area Based Management Plan of the Sta. Cruz River system, the targeted area for rehabilitation in Laguna.
