Laguna Water’s laboratory is now certified by the Department of Environment and Natural Resources (DENR) to analyze water -- including freshwater, groundwater, water for various uses, and wastewater samples. The scope of the certification includes testing the following parameters: chemical oxygen demand, fecal coliform, total coliform, true color, pH, settleable solids, temperature, total dissolved solids, and suspended solids.

Aside from its laboratory, the talents of Laguna Water are now DENR-recognized signatories. Designated personnel are Karla Gutierrez and Alyssa Penales for bacteriological analysis; Kristeen Alday and Kristel Parayo for physical-chemical analysis.

With this recent milestone, Laguna Water is now certified to analyze environmental samples for private companies and individuals, NGOs, and other government agencies, and local government units. The certification is valid for three years following Administrative Order No. 63, series of 1998, or the Guidelines for the Designation of DENR Recognized Environmental Laboratories.
