This study focuses at determining physicochemical and microbial properties, some selected heavy metals, anions and coliform bacteria in hand-dug wells and boreholes drinking water sources in Micheweni-district of Pemba Island, Zanzibar. Water samples were collected from 24 hand-dug wells and boreholes during dry season (December, 2015) and wet season (April, 2016) and analyzed for physicochemical parameters including pH, electrical conductivity, total dissolved solids, turbidity and heavy metals and anions analyzed were Cd, Fe, Pb, NO 3 − , SO 4 2− , PO 4 2− and Cl −. Total coliform and fecal coliform were analyzed. The analysis was done according to standard methods for water examination and reported based on the WHO prescribed limit for drinking water and TBS standard. The range of levels of parameters for boreholes and hand-dug wells respectively were: pH: 6.8 to 8.3 and 6.9 to 8.3; temperature: 27.3 to 30.1°C and 27.1 to 30.
