Lead is a priority chemical hazard that should be included in national drinking-water quality standards and monitored as part of drinking-water quality surveillance.
This document provides practical guidance to support the assessment and management of lead contamination in drinking-water supplies. Step-wise guidance is provided to support action when elevated lead concentrations are detected in drinking-water. It also explains why lead in drinking-water is an important issue and sources of lead exposure in water supplies. | »
It was 1 May 2020. The Covid-19 pandemic had reached South America. Brazil had the most cases and deaths of all countries on the continent.1 Its northeastern state Ceará was hit the hardest, with 16,529 confirmed cases and 1,102 deaths from the disease. 2 Washing hands frequently and thoroughly was the most important preventative measure against Covid-19. But in Ceará there was a shortage of water, and so even this simple measure posed a challenge for some people there, especially in rural areas. Lack of sufficient clean water had also brought extra pressure to hospitals, which could not operate properly without it. The Ceará state water company CAGECE was working day and night to combat the issue. | »
In 1996, when SISAR was created in the Brazilian state of Ceará, its main purpose was to bring access to water supply in rural areas where such service was not available before. These areas had been left aside by state water supply and sanitation (WSS) companies, which had predominantly focused on urban access to WSS services. From 1996 to 2016, SISAR’s coverage expanded dramatically, from 18 to 153 localities it reached operational cost recovery in 2012.
This success, which has encouraged the replication of the SISAR model in other rural contexts in the Brazilian states of Piaui and Bahia, is mainly based on a gradual improvement strategy and a specific labor arrangement. | »
