Geoeléct and hidrochemical study for mape the plume leachate derived of a landfill opened up in Mexicaltzingo, State of Mexico
Main Article Content
Abstract
This study describes the quality of the groundwater in the dump to open pit, a dump of the municipality Mexicaltzingo located in the State of Mexico. Three geoelectrics lines using method of electrical resistivity image were realized. Also hidrochemical and hydrogeological studies were realized in the site. The site has six piezometers to a depth of 30 m, upstream, downstream and within the landfill to monitor the quality of water and measure the static level. Piezometers were named as PZ1, PZ2, PZ3, PZ4, PZ5 and PZ6. The distribution of total dissolved solids (STD) at the site was measured. The aquifer is unconfined type. The top of the aquifer is covered by a surface layer dry and underlying by Upper Toluca formation. Total solids dissolved (STD), represented by the ions Na+, K+, Ca2+, Mg2+, Cl-, SO4 2-, HCO3 - and NO3 - were estimated to be greater than 4000 S cm-1 at a depth of 12 meters in the area of geoelectrical study lines. Found the ground water is not suitable for use domestically in this area.
