caldwell county regional water and wastewater planning study

Pollution sources listed in the Plum Creek Watershed Protection Plan includedpets, sheep, goats, horses, cattle, deer, hogs, croplands, urban run-off, septicsystems, WWTF, and oil production facilities. Pollution contributions includebacteria, nutrients, and other constituents such as E.coli. Voluntary monitoring ofthese constituents in Plum Creek will continue until recommended standards aremet.Estimated loading sources of pollution in the Plum Creek Watershed are listed inTable 10-1. The Plum Creek Watershed Protection Plan monitored the streamlevels and collected data at monitoring stations to estimate pollutant loads andrequired reductions. A Load Duration Curve (LDC) to predict point and nonpointsource pollution was used with the SELECT approach to identify sources andcontributions. SELECT is a Spatially Explicit Load Enrichment Calculation Tooldeveloped by the Spatial Sciences Laboratory and the Biological and AgriculturalEngineering Department at Texas A&M University.URBANWASTEWATERAGRICULTUREWILDLIFEOTHERTABLE 10-1Potential Pollution SourcesSource Bacteria Nutrients OtherRun-off x x xPets x xSeptic Systems x x xWWTF x x xSheep and Goats x xHorses x xCattle x xCropland x x xDeer x xFeral Hogs x xOil andProductionsxKlotz Associates Project No. 0972.000.000January 201010-5Caldwell County Regional Water and Wastewater Planning StudyFinal Report
