Texas Water Quality Board, Administrative Operations Division2010-02-152010-02-151975http://hdl.handle.net/1969.3/2264218 pgs. and 2 mapsThis report has been prepared in accordance with an agreement between the Texas Water Quality Board and the South East Texas Regional Planning Commission (SETRPC) covering the improvement of steady-state mathematical models of stream water quality for the Beaumont- Port Arthur 208 Area. As required in TASK 2.42, the purpose of the report is to identify additional data requirements to improve parametric coverage and to improve the accuracy of existing models. The model can then be employed to assess the water quality management alternatives in the area under projected future waste discharge conditions, and to indicate those areas in which additional controls of waste discharges may be necessary. This report includes a summary of the existing water quality as well as the historical hydraulic and chemical quality data. Physical and chemical parameters necessary to calibrate or verify the mathematical models are identified by frequency, location, and scheduling. Sampling stations and point source discharges are described verbally anad located on maps of the area.modelingmanagementwaste treatmentwater qualitypoint source pollutionwater quality managementsewagepurificationmeasurementmathematical modelsBook
