Studies of diarrhoea in Quindio (Colombia): problems related to water treatment

This paper studies the association between fluctuations in rates of diarrhoea among children less than 5 years old in Armenia (Quindio) and variations in the application of chlorine in the aqueduct of the city. The study shows that to a great extent diarrhoea morbidity can be explained by the application of chlorine which does not reach useful levels of concentration during the required time. The article concluded by recommending the improvement of existing treatment plants and investing the necessary resources in new plants to insure the quality of water.
