At ACCIONA AGUA SA PHILIPPINES BRANCH, I performed physicochemical and microbiological analyses of water for the Manila Water WTP in Pakil Laguna. I also conducted routine testing and jar testing to support water treatment operations.
At Maynilad WTP, I served as Laboratory Chemist and Assistant Supervisor-OIC, overseeing daily laboratory operations and reviewing analytical results. I supervised jar testing and process investigations, and maintained SOP and QA/QC documentation.
As a Laboratory Chemist (Consultant) at INTERTEK TESTING SERVICES, I analyzed water, wastewater, and environmental samples under Standard Methods and ISO/IEC 17025 requirements. I also performed method validation and verification, QA/QC activities, and proficiency testing.
My work has included operating and maintaining instruments such as GC-MS, UV-Vis spectrophotometers, and TOC analyzers. I’m a Registered Chemist and Registered Chemical Technician, and I’ve also taught undergraduate chemistry at Visayas State University.
