Massive sewage spill leaves Long Island harbor ‘green’ as locals told to stay away

A massive sewage spill in a Long Island north shore harbor turned the water “like green” as health officials told locals to steer clear on Monday.

Some 30,000 gallons of partially treated sewage gushed into Port Jefferson harbor due to a treatment plant mishap.

“It was like green,” resident Gary Contes told News12. “I thought it was an oil spill or something.”

An electrical malfunction at Port Jefferson’s sewage plant caused an open flow into the water for about two hours, according to the outlet.

“Out of an abundance of caution, we are warning those who may choose to fish, canoe or recreate at the water’s edge to take steps to protect themselves and their families from potential pathogens,” Suffolk County Health Commissioner Gregson Pigott told the station.

Restrictions on local shellfishing have also been implemented.

Kids and pets, especially, should avoid the water, and a person should rinse down with clean water immediately if they come into contact with the sewage, health officials said.

Warning signs to seek medical attention include nausea, vomiting, diarrhea, skin, eye, and throat irritation, in addition to allergic reactions, and difficulty breathing, according to the Village of Port Jefferson.

The entire area should be avoided until 9 a.m. Wednesday.
