This article talks about how Maryland is the latest state to take steps toward bringing back freshwater mussels to filter water.
Under the waters of the Patapsco River in Maryland, new life is forming.
The Maryland Department of Natural Resources has planted freshwater mussels into the river in hopes of restoring a population of molluscs that once lived in the waters. And the Maryland project is just one of many in the country attempting to save nature’s water filters.
Freshwater mussel species, unlike those that dwell in salt water, are not eaten. But they do serve a large purpose for the ecosystem. They filter water. A lot of water.
