However, water contaminated with pathogenic bacteria or thermotolerant coliforms (TTC) will not achieve the SDG target of clean water in the lives of people around the world.  Although the international water standard for thermotolerant coliform (TTC) levels is 0 CFU/100ml, in our sample of 111 water services, the maximum TTC counts were 71 CFU/100 ml and the mean was 4 CFU/100 ml.  Thermotolerant coliform counts were above the permissible standard values for nearly 40% (n = 111) of the basic water services.  Approximately one third of the basic water services sampled, deemed "functional" by international standards, do not provide potable water due to thermotolerant coliform (TTC) levels.
