About the HNU Water Testing Laboratory
Holy Name University realizes its mission in protecting the integrity of creation through its Water Testing Laboratory (WTL).
When the Water Testing Laboratory temporarily stopped operation after the earthquake in 2013, a demand for water testing service grew since then. Due to this demand from the business sectors, government and non-government organizations of Bohol, the HNU Administration decided to re-open its water testing laboratory. What used to be the hospital laundry facility was converted into the new HNU Water Testing Laboratory. On August 12, 2022 the DOH accreditation team came to evaluate the laboratory. On August 24, 2022 the hard copy of the accreditation certificate was delivered to the laboratory. The new HNU Water Testing laboratory is accredited under service capability Category A: Microbiological (Membrane Filtration Technique) and Category B: Physical Chemical. It is the only water testing facility in Bohol which can provide microbiological, physical and chemical analysis of drinking water.
