Abstract

La calidad del agua destinada al consumo humano se puede evaluar en función de un conjunto de características. En la literatura se han propuestos diversos indicadores que permiten integrar la información de dicho conjunto en un único valor o índice global. Por otra parte, los usuarios deben pagar un precio por el agua que consumen. En este artículo se van a considerar ambos aspectos: la calidad del agua y el gasto familiar por su consumo. Dos son los objetivos principales que se abordan: el primero se centra en la comparación de tres indicadores globales de calidad del agua, aplicados a los datos más recientes sobre agua superficial que proporciona la Confederación Hidrográfica del Júcar; el segundo consiste en estudiar hasta qué punto existe o no relación entre la calidad del agua para el consumo en los hogares y el gasto que le supone a éstos dicho consumo. Los resultados confirman la existencia de una relación positiva y estadísticamente significativa entre los tres indicadores de calidad utilizados, mientras que no hay evidencia empírica de que exista tal relación entre los conceptos de calidad y gasto. The quality of the water intended for human consumption can be evaluated depending on a set of characteristics. Many different indicators allowing to integrate the information of this set in a only value or global index have been proposed in the literature. On the other hand, the users must pay a price for the water that they consume. In this paper both aspects have been considered: water quality and familiar expense for its consumption. Two principal objectives are approached. The first one deal with the comparison of three global indicators of water quality applied to the most recent information on superficial water that provides the Confederación Hidrográfica del Júcar. The second objective is the study of the relation between the quality of the superficial water for human consumption, and the expense that it supposes to the homes. The results confirm the existence of a positive and statistically significant relation between the three indicators of quality used, whereas there is no empirical evidence of such relation between the concepts of quality and expense.
