A alternativa correta é a letra D) Apenas I e IV estão corretas. O manancial é responsável por fornecer água para o processo de tratamento e, em seguida, o tratamento é realizado para remover impurezas e matar microorganismos presentes na água. O pH é ajustado em outras etapas do processo de tratamento.
