The study was conducted to determine the water quality for domestic purposes at the Adventist University of the Philippines (AUP) dormitories. Specifically, itidentified the level of heavy metals such as lead(Pb), copper(Cu),chromium(Cr),total dissolved solids (TDS) and pH. The results of water quality analyses were compared with the standards set by the Philippine National Quality Standards for Drinking Water (PNSDW); (0.01 mg/L for Pb, 1.0mg/L for Cu; 0.05 mg/L for Cr;500.0 mg/L for TDS and 0-14 for pH).Water quality analyses were done using atomic absorption spectrophotometry (AAS) for Pb and Cu, respectively, photometric for Cr, gravimetric SMEWW 2540C for TDS and laboratory in situ for pH. The results of the analyses revealed that all water samples collected from the dormitories were far below the water quality than standards with reference to the parameters considered. Therefore, the water being used for domestic purposes such as for drinking, preparing food, bathing, washing clothes and dishes and brushing teeth is potable and safe.
