Sanitary and aesthetic quality of Egyptian coastal waters of Aqaba Gulf, Suez Gulf and Red Sea
During the course of 7 years (1998-2004), five field trips were performed annually in January, march, May, July and September. 1400 water samples (200 samples/year) were collected from 40 coastal sites covering the recreational areas as well as different hot spots and some protectorate areas. Hydrochemical parameters including temperature, salinity, pH and dissolved oxygen as well as bacteriological parameters including total coliforms, E. coli and fecal streptococci were investigated. Inverse relationships were observed between salinity and each of total coliforms (TC) (r = -0.149, P ≤ 0.05) and E. coli (EC) (r = -0.147, P ≤ 0.05) in the Suez Gulf, whereas in Red Sea there was an inverse relationship between temperature and fecal streptococci (FS) (r = -0.17, P ≤ 0.05). The present study suggested that E. coli was the most appropriate indicator during the course of study concerning variation in time and locations. Equivalent to 80% of analyzed samples compliance with the current standard, 30 sites (75%) of 40 studied sites were unpolluted whereas 25 sites (91%) of 28 recreational areas was recommended as unpolluted and approved for safe recreational activities.
