November 3 Discussion

On November 3 we'll continue the discussion of land use characteristics, work through a case study simulation, and then discuss point source and non-point source impacts.

We'll also focus a little more closely on Four Mile Run, and then as time allows, explore physical characteristics of watersheds.

Next week (November 10), we'll explore watershed stewardship and advocacy.

“We conclude that petitioners have demonstrated a substantial possibility of success on the merits of their claims,” the judges wrote in their decision, explaining that the Environmental Protection Agency’s (EPA) new guidelines for determining whether water is subject to federal control — based mostly on the water’s distance and connection to larger water bodies — is “at odds” with a key Supreme Court ruling.
