Description
Summary:The current problem related to the supply of drinking water for the metropolitan area of Monterrey, which comprises of five million inhabitants, and the important role played by the El Cuchillo Dam, found downstream of the Santa Catarina River basin as a surface source of drinking water for the city, renders this river an interesting site for assessment. This work evaluates the degree to which the surface water and the subsoil of the river are affected by emerging organic pollutants due to their existence, even at low concentrations, representing a toxic risk enhanced by the absence of stricter standards for regulating these substances. Based on fieldwork, three discharge points that could affect the quality of the surface water were selected: two points on the river stream, and three groundwater wells. Gas chromatography results showed the presence of BisPhenol A (BPA) and bis(2-EthylHexyl) Phthalate (DEHP) in both the surface water and subsoil at different seasons of the year. The highest concentration levels in the samples taken from both types of water were 0.9 and 60 μg L −1 for BPA and DEHP, respectively. Results of this research did not reveal the level at which the aquifer is affected by these substances.
