Abstract:

Considering that universal access to sanitation services is one of the Brazilian National Plan for Basic Sanitation objectives and one of the sustainable development goals (SDG), this research aimed to evaluate the supply coverage and the quality of water distributed in Brazil in 2019. DataNational Sanitation Information System (SNIS) and Water Quality Surveillance Information System for Human Consumption (Sisagua) databases were evaluated. It was found that 82% of the population has access to safely managed drinking water services, being this percentage even lower considering only North (58%) and Northeast (74%) regions. Most of the population is served by Water Supply Systems (WSS); however, in the North region, 6.6% of the population is served by WSS and 7.2% by Collective Alternative Solution (CAS) without treatments. For the Total Coliforms parameter, 21.9% of CAS samplesthe North region were outside the potability standard, while for the residual disinfectant agent, 40.6% of WSSthe Northeast region were outside this standard (with 19% of the samples having a concentration of the disinfectant agent above 5.0 mg/L, and 81% of the samples presenting concentration lower than 0.2 mg/L. Therefore, part of the population may be vulnerable to risks related to water quality since Brazil is still farreaching the National Plan for Basic Sanitation and SDG targets for universal access to safe water for all its population.
