A busy playground next to the Red Hook Houses. On the side, parents and grandparents are waiting.

"They didn't come to the house yet," said Patrina Owens, a Red Hook West resident. "They sent out those letters, but no one has come to the house yet."

Residents here are waiting for the city to assess their apartments for lead paint.

When asked if she is nervous about it, Owens said, "Of course. I mean, I got a grandbaby in the house. I mean, it's not healthy for anyone, but I mean, I'm concerned about her."

These fears are not unwarranted. NY1 has obtained never-before-seen test results from public housing apartments.  

The station reviewed 938 lead tests conducted on housing authority apartments from October 2016 through mid-April of 2017.

These tests were conducted as tenants moved out of their apartments, covering a time when the city was scrambling to restart its lead inspections after failing to do them for years. 

In the tests NY1 reviewed, 46 percent came up positive for lead paint, with some developments having a much higher number of positives.

The Alfred E. Smith Houses in Manhattan came back with 26 positive lead paint tests. 

In Brooklyn, Red Hook West had 19 positive results.  

Move east to Flatlands, and Glenwood Houses had 18 positive results. 

Out in Astoria, Ravenswood also came back with a high number, 17. 

"It doesn't surprise me because the Red Hook Houses were built in the 1930s and I believe they stopped using lead-based paint in the 1970s," said Karen Blondel, a Red Hook West resident.

That's true. Housing authority officials say some developments have more lead because of when they were built.

Take the Smith Houses, built in the 1950s long before the use of lead paint was a concern.

Still, officials at the authority and City Hall have said the universe of apartments that may have lead paint is small. It amounts to a little more than one-quarter of their housing stock.
