NPS (Nonpoint source pollution watershed flow) Model

The NPS model is a hands-on representation that allows students to understand how water sources can become polluted from nonpoint sources. The plastic structure has industrial, undeveloped, agricultural, residential and roadway components, complete with individual houses, trees, cars, tractors and cows. When "rain" falls on the model, runoff carries "pollution" into the city lake.
