According to an engineering report, the site of former New York Governor John Jay's childhood home in Rye, New York is contaminated with pesticides dumped by Westchester County's Playland Amusement Park.
The Journal News said that FPM Engineering Group found traces of lead, arsenic, and other pollutants in two piles of fill, one of which is located on what is planned to be an organic garden.
The report, which was authorized by the Jay Heritage Center, said the levels in the fills exceed New York State's safety standards.
When reached out for comment, Playland referred NBCNewYork to the Westchester County's Parks Department who had no comment on the study.
The New York State Department of Environmental Conservation said they will look into the ecological effects resulting from the waste.
"We have nothing on Playland in our databases. Our staff took a quick look at the numbers and said it didn't seem to be too bad in terms of (exceeding the standards) for residential property, but we're looking into it further," New York's DEC spokeswoman Wendy Rosenbach told The Journal News.
Last month, the county brought in the fill to revamp the 23-acre land, which includes filling in an 11-foot deep pool, reported the Journal News.
The Jay residence and Playland Amusement Park are both national landmarks.
