MANILA Water Laboratory Services (MWLS) was recently acknowledged as a Laboratory of Excellence after rounds of proficiency testing by Waters ERA in August and September this year, with results based on comparison with over 300 laboratories across the globe. To support its certifications and accreditations from relevant agencies, MWLS sought this latest recognition as validation that its methods and processes pass world-class standards to ensure that the water that reaches customers’ water meter is clean and safe to drink and wastewater effluent remains safe to support biological life in rivers and waterways.
MWLS Head Joy De Vera shares that this is part of the laboratory’s efforts towards continuous improvement. “Manila Water Laboratory Services commits to consistently provide accurate and reliable test results that is why we pursued this Proficiency Testing by ERA and we are pleased to have received satisfactory rating in all test parameters evaluated,” adds De Vera.
These parameters include total dissolved solids (TDS), calcium, magnesium, chloride, sulfates, calcium hardness and total hardness for drinking water; and total solids (TS), total suspended solids (TSS), settleable solids (SS) and oil and grease (O&G) for wastewater.
According to its website, US-based Waters ERA “has evolved to become the premier providers of Proficiency Testing (PT) products and Certified Reference Materials (CRMs) to thousands of laboratories around the world and across multiple industries… serving laboratories in more than 80 countries.”
MWLS is likewise accredited to ISO 17025:2017 standards on quality management system for testing and calibration laboratories and accredited by the Department of Health (DOH) to Philippine National Standards for Drinking Water (PNSDW). It is also recognized by the Department of Natural Resources (DENR) as an Environmental Laboratory.
