What comes out of here?

It looks so innocuous. It's just a small inlet leading into Horsepen Bayou, a tributary of Armand Bayou. But this inlet is actually fed by an outfall from a sewage treatment plant just a few hundred meters upstream.

The sewage is treated, but it's unknown how many nutrients the outfall contributes to the Bayou, or how its output influences the growth and establishment of restored marshes downstream or the invasive plants that are spread throughout the Bayou.

Welcome to Allison Parnell--she will be seeking answers to these questions and more for her master's thesis.
