The MIMAROPA Regional Project Monitoring Committee (RPMC) together with the Environmental Management Bureau conducted an emergency field validation or water quality testing of the Mansabang Communal Irrigation System (CIS) in Boac, Marinduque on August 14, 2018. The water testing, requested by Governor Carmencita O. Reyes, aimed to check the toxicity level of the river water that will be used in the CIS project.

The monitoring team that conducted the water quality testing was composed of personnel from NEDA, local monitoring team of Marinduque together with representatives from the DENR-EMB, NIA-Irrigation Management Office in Marinduque, local government unit (LGU) in Boac, Marinduque State College and Norwegian Mission Alliance.

The EMB collected samples from four different locations of the Boac River. The first sample (midstream) was taken at Barangay Tampus where the construction of the corewall of Mansabang CIS was located, second sample (downstream) was taken at one of the irrigation canal of the irrigated farmlands, while the third and fourth samples (upstream 1 and upstream 2) were taken at Barangay Hinapulan.

According to EMB, the on-site testing conducted showed that the waters collected passed the water quality standard except that the instrument used has limitation on the measurement of the toxicity level and heavy metal content of the water. The samples were brought to Manila for further testing. The result of the water analysis will take about 20 days.

 The team also took time to check the status of the construction of the corewall of Mansabang CIS wherein as of June 30, 2018 its physical accomplishment is at 30.38 percent. The project was terminated on April 16, 2018.


The NIA, meanwhile, conducted bidding for the completion of the Mansabang CIS worth P8.115 million last July 25. A notice of award was then issued to the winning contractor on August 1, 2018.

The RPMC will regularly monitor the implementation of the project and the water quality to be used for irrigation.
