The term asbestos refers to six unique fibrous minerals mostly used in the production of asbestos cement sheets and pipes. According to the World Health Organization and the International Agency for Research on Cancer (IARC), there exists at least "sufficient evidence" that all types of asbestos may cause cancer in humans (mesothelioma, lung cancer, laryngeal tumor and ovarian cancer). The only asbestos limit in drinking water is 7 million fiber/liter. This study is a narrative synthesis about the possible hazards to human health related to the presence of asbestos in drinking water. The various scientific studies and epidemiological reports examined highlight that there is an ongoing debate on the possible carcinogenic risk associated with asbestos exposure through ingestion. Nevertheless, considering the latency with which diseases caused by asbestos may emerge, control measures should be adopted.
