Importance of soil properties in the risk of groundwater contamination

Mostrar todas las versiones(2)

Aquifer vulnerability is frequently estimated through methodologies that do not consider the main physical and chemical soil parameters. Soil characteristics were determined at a semiurban region with mixed activities at the surroundings of Buenos Aires city. A soil attenuation index (AI) was propos...

Soil characteristics were determined at a semiurban region with mixed activities at the surroundings of Buenos Aires city.
