Unit Area Loading in the Urban Development Context
Given: a)
Land Use Acres
Forest 1400
Developed 75
Commercial 30
Agriculture 500
b) Point Source Pollution: wastewater treatment plant; Q = 50,000 gpd
Phosphorus discharge; q = 1.0 mg/liter
1. Calculate the total Point Source and Non-point Source phosphorus load using the unit area method.
2. Calculate the percent contribution of each land use and the treatment plant.
3. Discuss the implications in using the Unit Area Method
Calculating annual pollutant loads
There are many implications to consider when using the UAL method to calculate pollution loads. The first arises when using the pollutant loading factors which have been established using either regional or nation
