PORT JEFFERSON - Port Jefferson residents are concerned about possible leaking toxins at the site of a former aviation manufacturing company.

Diana Mercury showed News 12 photos of what she says is an unknown substance leaking out of a drum at the old Lawrence Aviation site.

EPA officials do not think the fluid is toxic, but say there will be a full investigation.

The EPA also told News 12 that the property owner, Gerald Cohen, claims he doesn't have money for security at the site anymore.
