Resumo
This study evaluated the turbidity of 5034 water samples collected at the water supply systems of 224 municipalities in the State of Goiás
during a period of 24 months, between 2011 and 2013. Samples were collected at the beggining, end and also in intermediate points of
water supply systems, as well as in areas with increased flow of people, such as hospitals, clinics, schools and nurseries. The results showed
that in the rainy season were found 78.1% of occurrences of turbidity over 1.0 NTU in relation to drought, and the average rate was 0.98
and 2.20 NTU, respectively, to periods of drought and rainy. It was observed that 23.91% of the evaluated samples showed turbidity values
greater than 1.0 NTU and 3.5% greater than 5.0 NTU. There is a variation between the results presented, that is from 1.9% to 8.0% of the
mesoregions and 0 to 8.9% incidence of microregions with turbidity higher than 5.0 NTU.
