A streets in the Dongan Hills section of Staten Island has been covered in sewage for almost three weeks, and Congressman Michael Grimm heard residents' pleas for help on Sunday.

Sewage filled Jefferson Avenue after Hurricane Sandy hit, and while many of the homes are structurally sound and power is back on, residents said they are now concerned about health hazards.

"We do not know what the impact is going to be in the long run. I have a six-year-old son and my wife. I am not bringing them back here because I don't know what is going to happen down the line," said Michael Barzal, a resident.

"I have been here from the moment that stuff came into my house. I have been cleaning and I still have it because it is tracked everywhere," said Linda Evangelista, another resident.

"The severity of the problem hasn't been captured. They think it's just 'Get the power back on, everything is fine.' That is not the case here. This is raw sewage," said Grimm. "This block is going to need substantial help and that is what we do."

Grimm said he contacted the homeowners' insurance companies and the city to get help.

NY1 reached out to the city Department of Environmental Protection on Sunday and was awaiting a response.
