An interesting experiment in water pollution management is taking place in the Bronx River estuary near Hunts Point in New York City. Scientists are testing the use of a ‘Mussel Raft’ for addressing nitrogen pollution from treated sewage that ends up in the water from a nearby treatment facility.
Mussels are known for their filtration properties and are being tied to lines on the raft to assist in water filtration. Non-edible ribbed mussels were chosen in the hope they would not be harvested to be eaten. The mussels filter about 1.6 liters of water (0.4 gallons) every hour.
