The Channel Team's water filtering lab inside a local cabin. The team will process 800 liters of water to extract as little as ~100mg of material found in a liter of Mississippi water.

Body
NASA's Delta-X Mission combines airborne remote sensing and field measurements to analyze water levels, vegetation, and sediment to understand how and where the Mississippi River Delta is changing.
