GONZALEZ-DAVILA, R. P.; VENTURA-HOULE, R.; GARZA-REQUENA, F. R. De la y HEYER-RODRIGUEZ, L.. Physicochemical water characterization of La Vega Escondida Lake, Tampico, Tamaulipas, México. Tecnol. cienc. agua [online]. 2019, vol.10, n.1, pp.1-29. Epub 21-Abr-2021. ISSN 2007-2422. https://doi.org/10.24850/j-tyca-2019-01-01.
La Vega Escondida Lagoon is located northwest of the municipality of Tampico, Tamaulipas. It is a protected natural area, in the suburbs area of Tampico, Madero and Altamira. This lagoon is a source of potable water supply for the city of Tampico and provide other ecological benefits. To protect both the ecosystem and human health it is important to know the physicochemical composition of the water in this lagoon. This study assessed the levels of physicochemical parameters of water (pH, electrical conductivity, total solids, temperature, chlorides, hardness, alkalinity, sulphates, chemical oxygen demand and dissolved oxygen) and its spatial distribution in the lagoon. The results obtained were compared with the ecological criteria of water quality (CE-CCA-001-SEMARNAT, 1989) and with the Mexican drinking water standards (NOM-127-SSA1-1994). Results showed that the water of the lagoon complies with most quality parameters required to maintain the aquatic life and to human consumption, except for total suspended solids (SST). The patterns of spatial distribution of the physicochemical parameters were heterogeneous and they showed significant differences in the parameter OD at the different depths studied, as well were founded differences at sampling points for the pH and EC, at the level of significance of 5%.
