Testing Water Quality in a Municipal Wastewater Effluent Treated to Drinking Water Standards

Project Summary

The goal of this project is to test the quality of wastewater effluent that has been treated to drinking water standards at the Raw Water Production Facility, a full-scale potable water reuse facility at Big Spring, TX. Samples from various locations in the treatment train will be analyzed for pathogens, pharmaceuticals, hormones, and other constituents of emerging concern. Surrogates will be monitored and correlations developed between surrogate concentrations and the corresponding primary constituents. The main deliverable for the project will be a resource document that provides monitoring guidelines for direct potable reuse projects in Texas.
