Bacterial contamination and chemical content were examined at rain water reservoirs. The randomly chosen reservoirs located at Alzaroq area, part of Misurata city - Libya. Water samples from these reservoirs were collected to determine the bacterial content and analyzed for presence of some chemical elements. The present study showed that twenty five samples were contaminated with bacteria, where the other two samples gave negative results using the presumptive test. Contaminated samples were examined on EMB agar and results showed that these bacteria belonged to the coliforms group. Completed test was carried out to confirm that. Indole test results confirmed that thirteen samples were contaminated with Escherichia coli. The chemical analyses showed that pH range of two tested samples were under permitted range of WHO. Calcium and Magnesium were high at some samples. Chloride, iron as well as electric conductivity and total dissolved salts (TDS) were at the permitted range
