Coastal marine environments are highly vulnerable to anthropogenic pollution from municipal sewage, industrial effluents as well as agriculture run-off and river discharges. Fecal contamination not only impairs water quality but also potentiates human health risks. In urbanized areas, possibly sources of fecal pollution can include deficient sewage treatment and leaks due to wastewater treatment plant outflows. Many coastal beaches are located near urban areas, others near river discharges, with input from agricultural and industrial wastes, so that potential risks of contamination may exist, whenever sewage treatment is not effective [1,8]. Therefore regular monitoring of the quality of coastal waters has been suggested, employing different sampling strategies, according to the specific characteristics of the recreational area in terms of physical-chemical parameters and number of bathers.
