Resumen:
Lake complex ``Lagunas de Montebello'' is a karstic system composed by
sixty lakes, all apparently connected. This system is localized at south
of Chiapas state, SE Mexico. It is considered one of most beauties
landscapes of the country. Main importance is due to climatic and
hydrological regulation of this region. However anthropic activities as
deforestation and waste water spills begin to produce risky conditions
to water quality. This work presents spatial and temporal variability of
water quality considering the study of ten lagoons through three
sampling periods. Two of these periods of field work, (april and
september 2013) consider sampling of only one point at surface in each
lagoon. A very extensive sampling was developed in august 2014 in ten
lagoons. Results show that this karstic system can be divided in two
groups of water quality. First group of lakes contains
calcic-magnesic-bicarbonated-sulfated waters and second group contains
calcic-magnesic-bicarbonated waters. At first group, is possible to
identify impacts related to inlet of waters high in sulfates and
chlorides, these solutes dilutes along two first lagoons. An independent
flow system rich in sulfates, probably of groundwater that circulates
deeply was identified. (C) 2017 The Authors. Published by B.V.
