SANCHEZ-NUNEZ, Juan Manuel et al. Basic environmental and geologic criteria to assess the location of a dump in Zinapécuaro, Michoacán, Mexico. Bol. Soc. Geol. Mex [online]. 2009, vol.61, n.3, pp.305-324. ISSN 1405-3322.

Zinapécuaro is located 50 km of Morelia, capital city of the state of Michoacan, this region has several problems because of domestic solid waste generated by 14 547 people; the actual disposal dump does not have any technical specifications, so it has environmental implications like soil, air and water pollution as well as unpleasant odors, harmful animals and groundwater resources pollution. The final disposition of solid waste in Zinapecuaro is one of the most critical and imperative problems to be solved. This study deals with basic technical proposal to establish the bases to select the suitable place for building a landfill according to the actual environmental regulation. The main criteria followed by this research were the Norma Oficial Mexicana NOM 083-SEMARNAT-2003 and four Mexican Technical Standards (NMX) that contain the procedures to determine the type of materials generated. According to statistical analysis applied to domestic solid waste sampling, the final disposition site at Zinapecuaro is classified as "C" type, the generation average is 0.62 kilograms per inhabitant per each day and the volumetric weight is 252.54 kg/m3. The kinds of rocks identify were basalts and volcanoclastic deposits range from Superior Triasic to Quaternary. Also presented lacustrine deposits and the most recent alluvial sediments are at the top of the stratigraphic column. The municipal authorities were interested in abandoned mine use for landfill, so Francisco Villa site fulfilled technical specifications for "C" type of disposal dump. We strongly recommend some specifc studies as a compliment to this research.
