NORWALK - The city has added two filter systems to stop debris from polluting Norwalk Harbor and Long Island Sound.
Forty-five filters were installed this week in catch basins at Veterans Park. Last year in South Norwalk, 275 filters were installed.
The Department of Public Works will evaluate how well the filters trap metals, sands and oils from street runoff that seep into waterways. The city is using filters from two companies, said Michael Yeosock, a public works senior civil engineer.
