My mech buddy and I changed out the spark plugs @ 77k miles. One had bad water corrosion (we think). We used new OEM plugs. I'm hoping this improves my mpg. What could cause this? Bad gas?

That's odd. No bad gas won't make the top of your spark plug turn green.
What the hell is that white stuff around the spark plug hole? Did someone try to seal it with silicone or something?
How does the spark plug boot on that cylinder look? Cracked? I'd defineatly consider at least replacing that one spark plug boot and get rid of that white stuff.

That green and white residue look like electrical contamination. One of your coil packs might be bad?

Inuvik might be more righter. The coil might be weak.
