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

BASINS Models

• HSPF (Hydrologic simulation program, FORTRAN)
• Qual2e
• PLOAD
• Swat

11
PLOAD

• Estimation of nonpoint sources pollution
• Allowance to use BMPs in calculation
• Wider Applicability

12
PLOAD Inputs

• Landuse data
• Watershed data
• BMP (Optional)
• Pollutant loading rate
• Pollutant reduction BMPs tables (Optional)

13
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

14
OUTPUT

• Total pollutant loads in watershed
• Per acre pollutant load in watershed

15
Pollutants

• BOD
• COD
• NOX
• NH3
• TP
• DP
• TSS
• TDS
• TKN

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
