Problem 1
Anthropogenic water pollution sources in Simsbury, CT
Simsbury mainly drains into dispersed stream systems that run into the Farmington River and
subsequently the Connecticut River. The lack of industrial activity in the area yields non-point source
pollution as the major form of anthropogenic pollution in the town. Common sources in the area include
animal pet waste, fertilizer and pesticide use (dichloropropane), car oil leakage, tetrachloroethane
leaching from PVC piping, and chlorine as well as haloacetic acids from water chlorination. Considering
Simsbury population of 23,000 people, we can estimate at least for fertilizer

Assuming there are 8,000 homes in Simsbury, and each uses 40 lbs of 5% Nitrogen and Phosphorus
fertilizer every year and 10% enters water sources:
16000 lbs of N and P entering water sources
Problem 2
This figure was obtained using .1 gram of Nitrogen equaling .0071394 moles in water according to the
specifications in the problem.
Increasing the viscosity of the solvent by a factor of 10 yields
While decreasing it by a factor of 10 yields
Changing the source of pollutant to be a curve instead of a line,
