Abstract. Katili L, Baderan DWK, Kumaji SS. 2023. Analysis of drinking water quality based on biological, physical and chemical parameters in Lekobalo Village, Gorontalo City, Indonesia. Intl J Bonorowo Wetlands 13: 22-29. Village is a part the Indonesia area, which has not yet received full clean coverage. Therefore, community used wellsprings as source water. An open tank around wellspring been for people surrounding. It becomes place household chores such bathing, doing laundry, serving lavatory.

Sample collection using sterilized bottles from laboratory, data obtained were analyzed descriptively. aims determine physical, parameters. The revealed Lekobali biological parameter considered polluted Escherichia coli coliform bacteria. findings average score E. 10.3 MPN/100 ml 200.5 mL. In parameters, relatively good with an temperature 20°C, turbidity NTU, scentless, tasteless, colorless. criterion did meet TDS (Total Dissolved Solid), 1,525 mg/L. According parameter, some arsenic (As) 0 mg/L, fluoride (F) 1 nitrite (NO2) 0.02 nitrate (NO3) 3.6 iron (Fe) 0.12 Power Hydrogen (pH) 6.6 mg/L manganese (Mn) standard qualification are chromium (Cr), cadmium (Cd), scores 0.34 0.047 can be one government's databases input developing programs activities improve control pollution.
