Water is the basis for the economic, social and urban growth and development of societies. Therefore, this paper specialized to study the most important water sources in Al-Qubbha town in eastern Libya, which represented in (Ain Al- Daboussiya) wellspring and groundwater never the less the town suffering from water shortage problems. Thus, a survey was conducted, in purpose of collecting water consumption data for the available sources; taking into account, previously the only sourcefor this area was Ain-Daboussiya; whereas, groundwater becomes the main one. The results showed thatAin Al-Daboussiya currently covers only10% of the residential area. In addition,52.2% are directly supplied by groundwater, whereas they never have an access to Ain Al-Daboussiya; because of the complete absence of the infrastructure. Based on these results, some laboratory tests were conducted to a number of samples of groundwater wells to confirm that increasing reliance on underground water with the absence of sewage net works is reason for biological pollution with sewage wells leaking. Consequently, laboratory results showed that most old wells have an indicator of biology pollutions.............................
