The aim of this article is to address a current problematic, which is concentrated in one of the most iconic locations in the state of Chiapas, Mexico. It is about a series of lakes found out at the Parque Nacional Lagunas de Montebello where has presented important alterations detected since the beginning of the 21st century. Making use of inverse modeling hydrogeochemical, it seeks to identify the predominant hydrogeochemical process in the place, since the chemical condition of the water will be known in greater detail in its constant interaction with geological conditions of the site to determine the degree of alteration owing anthropogenic activities developed around it, such as agriculture, industrial discharges and sewage that reach the lakes.
Finding due to geological framework of the karst region, where there are rocks made of dolomites, limestone and plaster formations, one of the principal processes determinated by the modelation and comprobated by the comparation in site, is the precipitation of the plaster proper to the low solubility, reactions of oxidation and reduction of the organic matter, precipitation or dissolution of nitrogenous elements and salts that came from the unloading done to the bed of the great river that feed the study site.
