Officials are holding a community meeting this weekend about the spike in cases.
John Schneider teaches history and knows Keyport extensively. He's written books on the area, including a book about the Old Aeromarine Industrial Park.
For decades, it has been a major concern for residents who say dozens of neighbors have died of cancer and dozens of others have been diagnosed with cancer.
They want to know once and for all if the site has created a cancer cluster.
Ginger Morris is a longtime resident, and her son became curious after toxic slag was discovered along the shore near the site.
It was listed by the Department of Environmental Protection as a landfill.
The Morrises have relatives who are battling cancer.
"Nothing has been done since 2010 when they knew it was causing and did nothing. Why? That's a big question why?" Morris said.
Sal Liquori lost his son to cancer 3 years ago.
His home sits right next to the site and is determined to get to the bottom of what he says has been disasterous to the town he loves.
