The Wrack

This is my final week in Maine as a research and coastal training program intern for the summer. I have mainly been studying the detrimental effects of nitrogen runoff. The three-year project that I helped start looks at Branch Brook and the Merriland River in the Little River Watershed. We selected 20 sites to analyze nitrogen runoff and how it affects the fish, the macroinvertebrates, the river habitat, and the water quality itself.

Danger seeps from your garden.

Fertilizer causes tomatoes to ripen larger and plants to grow taller. But applying more than your plants need can have a devastating effect.

The rain washes your excess fertilizer, either manure or chemical, down the road and into the nearest water source. There, it mixes with water traveling from other gardens, farms, and power plants to create a stream of nitrogen and phosphorus. The stream pours directly into the marsh.

It felt great to be back at the Wells NERR after being away for four months, especially since I had spent much of that time wading through reams of data on dissolved oxygen, chlorophyll-a, and dissolved organic nitrogen from our four System Wide Monitoring Program (SWMP) sites in the Webhannet and Little River estuaries.
