Nabbing Nitrogen Flash Mob: What We Learned

Nabbing Nitrogen results
Nitrogen levels were high at every place we sampled. The highest levels of
nitrogen were found closer to land, in tidal creeks and near combined sewer
overflows. Lower nitrogen levels were found further from shore.

On Sunday morning, July 10th, 2016, at precisely 10:10 a.m., 97 people knelt down along the edge of Portland Harbor and scooped up small vials of water from Casco Bay. They were not praising Poseidon—they were Nabbing Nitrogen.

A recent heavy rain had flushed a surge of stormwater into the Fore River, so we were not surprised that
the analysis of their water samples found elevated levels of nitrogen. The most important takeaway of the event, though, was that there is an amazing Casco Bay community of volunteers ready and willing to get involved when we send out a call to action!
