Assessment of the origin of microbiological contamination of groundwater at a rural watershed in Chile Agrociencia
Valenzuela,Mariela; Mondaca,María A.; Claret,Marcelino; Pérez,Claudio; Lagos,Bernardo; Parra,Oscar.
In a rural watershed in Chile, the scarce groundwater available represents almost the only water source both for agriculture and domestic use. This water has microbiological quality problems, which result in an agricultural and local economic development constraint. Contamination can come from punctual or diffuse sources. Characterizing the microbiological quality of groundwater allows both to identify sources from the point of view of whether they are point or non point -thus facilitating their reduction or elimination- and to determine health hazards likely to affect the population in the area under study. This study aimed to improve the state of knowledge on the microbiological quality of groundwater at a rural watershed. Forty two wells were seasonally...
