Paper Summary

The study tested methods to reduce pollution in highway runoff. They looked at two types of systems: a dry detention pond and a vegetated swale. By monitoring the water going in and out, they found that these systems can effectively remove pollutants like dirt, chemicals, phosphorus, and zinc from the water. This means that with the right design, these systems can help keep our water clean.
