The United Nations Environment Programme (UNEP) reports that once water is contaminated, it is difficult, costly, and often impossible to remove the pollutants. Currently, 80% of global wastewater goes untreated, and is contaminated by a wide range of substances, from human waste to highly toxic industrial discharges. The type and amount of pollutants in freshwater determines its suitability for human uses such as drinking, bathing, and agriculture.
Pollution of freshwater ecosystems can also impact the habitat and quality of life of fish and other wildlife. This can include pathogens (largely from human and animal waste), organic matter (including nutrients from agricultural run-off such as nitrogen or phosphorus), chemical pollution (from irrigation, domestic wastewater and runoff of mines into rivers) and salinity. Plastics, and chemicals of emerging concern, such as certain pharmaceutical products, are issues for which their extent and impacts on freshwater are largely unknown. A preliminary assessment of water quality in rivers in Latin America, Africa and Asia, “A Snapshot of the World’s Water Quality” (Ringler, et al., 2016), estimated that severe pathogenic pollution affects around one third of all rivers, severe organic pollution around one seventh of all rivers, and severe and moderate salinity pollution around one-tenth of all rivers in these regions.

The water quality assessment mentioned in the second paragraph estimates that the pollutant that affects more rivers in Latin America, Africa and Asia is:
Cinco municípios pertencentes a uma mesma região pretendem constituir um consórcio público para gerir, de forma integrada, o serviço de iluminação pública. A ideia de utilizar esse instrumento baseia-se em uma constatação técnica: caso os entes concedam o serviço à iniciativa privada de forma conjunta, o projeto ganhará escala financeira e terá maior capacidade de atrair boas empresas. Como os secretários municipais não têm experiência no assunto, é convocada uma reunião técnica com o objetivo de esclarecer dúvidas práticas sobre a constituição e o funcionamento do consórcio. Com base na situação hipotética e no disposto na Lei no 11.107/2005, o servidor público presente na reunião poderá afirmar corretamente que
De acordo com o Decreto no 6.017/2007, o instrumento pelo qual devem ser constituídas e reguladas as obrigações que um ente da Federação, inclusive sua administração indireta, tenha para com outro ente da Federação, ou para com consórcio público, no âmbito da prestação de serviços públicos, por meio de cooperação federativa, é denominado de
O município X possui uma empresa pública responsável pela prestação do serviço de saneamento básico e deseja extingui-la, tendo em vista os prejuízos financeiros acumulados ao longo dos últimos exercícios. No entanto, além da eventual alienação da empresa, os gestores precisam decidir sobre a continuidade da prestação do serviço, caso a extinção de fato ocorra, uma vez que é necessário garantir a manutenção desse serviço essencial. Considerando que a cidade possui uma extensa área urbana, cujos limites se confundem com os de municípios vizinhos, cogita-se, ainda, a adoção de uma solução conjunta para a gestão do saneamento. Com base na situação hipotética apresentada e no disposto na Lei no 11.445/2007, é correto afirmar que
