GIS study of occurrence and distribution of endocrine disrupting chemicals in wastewater treatment plant and groundwater in El Paso

Abstract

Many endocrine disrupting compounds (EDCs), such as nonylphenol (NP), bisphenol-A (BPA) and 17α-ethynylestradiol (EE2), are discharged by residential and industrial effluents into wastewaters. Some EDCs and metabolites escape elimination in wastewater treatment plants and enter the aquatic environment via sewage effluents. The objective of this study was to use EPA-BIOSCREEN 1.4 model and two geographic information system softwares, ESRI-Geographic Information System (ArcGIS 9), and the Groundwater Modeling System (GMS 6), to simulate the movement and distribution of EDCs. Since NP was the only organic pollutant detected in wastewater and treated water at Fred Hervey Water Reclamation Plant (FHWRP) during this study, this compound was used to develop two-dimensional and three-dimensional models to illustrate the potential impact of a contaminant plume in groundwater during a worst-case scenario. This study reflects that NP, EE2 and BPA do not represent a hazard for groundwater pollution in the production wells. ^
