  1. Use of GIS to Predict Pollution Contents in Surface Water Runoff By Muhammad Kashif Gill kashif@cc.usu.edu435-797-6456

  2. Introduction • Pollution problems in surface water • What EPA says • How GIS helps

  3. Objectives • To locate impaired reaches • To evaluate the extent of contaminants

  4. Data Sources • BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) • BASINS Utilities • USGS and EPA Data Sources

  5. Project Area

  6. BASINS Models • HSPF (Hydrologic simulation program, FORTRAN) • Qual2e • PLOAD • Swat

  7. PLOAD • Estimation of nonpoint sources pollution • Allowance to use BMP’s in calculation • Wider Applicability

  8. PLOAD Inputs • Landuse data • Watershed data • BMP (Optional) • Pollutant loading rate • Pollutant reduction BMP’s tables (Optional)

  9. Export Coefficient Method LP= ∑U ( LPU * AU ) where LP = Pollutant load ,lbs LPU = Pollutant loading rate for landuse type u, lbs/acre/yr AU = Area of land use type u, acres

  10. OUTPUT • Total pollutant loads in watershed • Per acre pollutant load in watershed

  11. Pollutants • BOD • COD • NOX • NH3 • TP • DP • TSS • TDS • TKN

  13. EMC

  14. Pollutant Layouts TP NOX NH3 DP

  15. Pollutant Layouts BOD COD TSS TDS

  16. Conclusions/Future Work • Major area in the watershed is severely affected by Phosphorous and Nitrogen • BASINS package can be utilized further to account for BMPs
