The aim is to improve the assessment of water and highlight the problem that currently represents that resource, the strengths and weaknesses in terms of water resources found in the research phase of development may well be extrapolated to typical situations facing the country and very specifically in many ASADAS of the Western Region. Finally, regular monitoring of drinking water quality in the canton of Grecia allows for environmental risk factors or to human health, which may have a ASADA or Municipality, to facilitate the timely development of criteria oriented to the prevention or correction any non-conformity.
