I think the local Hazmat team checked it out and it's just plain 'ol muddy water they're pumping....no EPA to worry about. Now IF that's the case...then maybe there's hope that the can of gas and case of motor oil in the trunk is still intact (IE: didn't leak out and contaminate the water and thusly get the EPA and Hazmat teams all excited). Also...wouldn't all the cosmoline leave a detectable residue if it's been in contact with water for 50 years?
