Water Quality Modeling of Guadalupe River, Central TX


Sampling Stations

Dr. Harkins was the field manager for a large multi-year water quality study for the processing of a large wastewater treatment plant permit renewal with studies completed to assess nutrient limitations, flow changes and downstream conditions. Dr. Harkins conducted an eighteen month water quality sampling project.  The scope of the project was to collect surface water samples in order to obtain information to assist in determining whether nutrient limitations on point source discharges from NBU’s wastewater treatment plants (WWTPs) will prevent the growth of excessive aquatic vegetation in receiving waters, as provided by the Texas Commission on Environmental Quality (TCEQ) regulations at 30 TAC 307.4(e).  As part of the water quality study numerous water quality studies related to point and non-point source loadings entering Lake Dunlap from the Comal and Guadalupe were evaluated to determine the impact of point and non-point source nutrient loadings on Lake Dunlap.
