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.

Recently, UK scientists and environmental organizations teamed up to create a smartphone app that allows users to track invasive plant species. PlantTracker “tells people how to spot invasive plants and lets them snap geo-tagged pictures of the species and submit them to the organizations to better help them manage the populations.” This crowd-sourced tool was developed by the UK’s Environment Agency, along with the Nature Locator project at Bristol University and the National Environmental Research Council’s Center for Hydrology and Ecology.
TreeHugger reports “invasive species are considered to be the second biggest threat to biodiversity after habitat destruction.”
