Groundwater quality studies were carried out inAsmaraaround Mai-Belaan area having a long history of waste water irrigation. The objective of this study is to identify the quality of groundwater where groundwater is used for domestic and agricultural purposes in Mai-Bela area. Samples from five locations were collected and analyzed. The  present  investigation  is  focused  on  the  determination of  Physico-Chemical  parameters such as temperature, electrical  conductivity, pH, hardness, total dissolved solids (TDS), alkalinity, salinity,sodium, potassium, calcium, magnesium, iron, manganese, bicarbonate, chloride, sulphate, nitrate, nitrite, ammonia, chemical oxygen demand (COD)and toxic metal determinations. Groundwater suitability for domestic and irrigation purposes was compared with World Health Organization (WHO) and Food and Agriculture Organization (FAO) standards. Most of the physico-chemical parameters were  found above the permissible limit  and so do the toxic metals except for COD, pH, temperature, Al, Cd, Cr, Cu and Zn which were found slightly lower than the standard limit which indicate the groundwater  in most of the study sites were not  suitable for drinking and irrigation purposes. This therefore, calls for appropriate treatment measures before the consumption of these waters by the populace to avoid long term accumulated health problems of these pollutants.
