The water specimen was examined microscopically for A. lumbricoides eggs and protozoan cysts using a concentrated technique. Of 8 locations, 4 locations (50 %, 4/8), Kembangan/Duri Kosambi, Teluk Gong, Pantai Indah Kapuk and left side of river mouth were positive for A. lumbricoides eggs and 2 locations (25%, 2/8), Kembangan/Duri Kosambi and Pesing Polgar positive for Entamoeba histolytica cysts.
