Oyster aquaculture in the Potomac River estuary could result in significant improvements to water quality, according to a new NOAA and U.S. Geological Survey study published in the journal Aquatic Geochemistry.

All of the nitrogen currently polluting the Potomac River estuary could be removed if 40 percent of its river bed were used for shellfish cultivation, according to the joint study. The researchers determined that a combination of aquaculture and restored oyster reefs may provide even larger overall ecosystem benefits. Oysters, who feed by filtering, can clean an enormous volume of water of algae which can cause poor water quality. Read more
There’s a lot to know about the world’s water crisis–as you can tell from the month of posts we’ve been doing on just this one topic. But if you’re new to the discussion, catch up in one weekend with these five documentaries. From in-depth background on the political, social, and economic factors that are causing the crisis to personal stories from people affected by it, you’ll understand the problem in a whole new way.
This seven-episode set (don’t worry: each is only about 22 minutes) highlights the way the water crisis affects everyday life in Bangladesh, Cambodia, Fiji, India, Kiribati, Philippines, Thailand, and Tonga. Watch as a community joins together to rescue a coral reef in Fiji, as women in India fight shortages by finding new ways to transport water, and as a handful of other men, women, and children stand up to claim enough clean, safe water for themselves and their neighbors.
