摘要

This study aimed to assess drinking water quality of the different water sources in Barangays Vigo, Yapas and Tinoblan in Laoang Northern Samar. Water sources were: deep well, pump well and communal faucets. Water quality is based on the physical, chemical and bacteriological properties for each of the eight sampling stations. Three sampling periods were made at an interval of at least 15 days from January-February, 2012. Findings revealed that most water sources were within the permissible limits in terms of color, odor, p H, total dissolved solids(TDS), salinity, dissolved oxygen(DO) and nitrite. However, hardness and alkalinity were beyond the allowable limits. All water samples were positive for fecal coliforms. Thus, this study concludes that all water sources tested are not safe and not potable.
