    A field work was conducted to study the density of the freshwater snail in relation to the vegetation cover as well as the physical and chemical properties in different watercourses. Two sites were selected in Giza governorate while, three sites were selected at Kafr El-Shiekh governorate. Water temperature, conductivity, total hardness, and pH were measured in the selected sites as well as bisphenol A (BPA) levels. Snail sampling was carried out and all types of macrophytes found in each site were collected, identified and coverage. Nine snails species namely Biomphalaria alexandrina, Physa acuta, Planorbis planorbis, Lymnaea natalensis, Bulinus truncates, Bellamya unicolor, Melanoides tuberculata, Helisoma duryi and Lanistes carinatus were identifi ed. B. alexandrina was the most enumeration of snail species. The percentage of total snail species (75.47 %) was recorded at 28 °C as compared to 5.86 % recorded at 34 °C. Five species of aquatic vegetation were identifi ed, two of them correlated positively and signifi cantly with various snail species. Sites in which snails associated with macrophytes were characterized with higher ranges of chemicals, dissolved oxygen, and conductivity. In conclusion, the most important of the associating vegetation was L. gibba which correlated with B. alexandrina and served as an indicator plant.
