New York City Housing Authority officials appealed the results of virtually every positive lead test at their buildings for nearly a decade, figures released late Sunday show.

NYCHA challenged 95 percent of the lead orders it received from the city Department of Health between 2010 and 2018.

And of the 211 cases it apppealed, DOH decided not to pursue 158.

A DOH spokesman told the New York Times, which first reported the figures, that the agency withdrew because its staffers believed the initial tests were simply coming back wrong.

Meanwhile, private landlords rarely appealed the DOH findings. Of the 5,000 positive lead tests at privately owned buildings over the same time period, only 4 percent were challenged.

NYCHA’s scheme to dodge lead findings via bureaucratic appeals was first outlined by federal prosecutors in a lawsuit brought against the authority in June.

“It is NYCHA policy to contest each and every NYC DOH order to abate lead paint,” they alleged. “Success in the contestation process does not answer the question whether the child was poisoned by lead paint in the home.”

More than 1,100 children have tested positive for lead in New York City’s public housing since 2012.
