Since PEG is not charged and would not co-polymerize with AA, 
I can't see how trace amounts of PEG (the only kind possible as 
far as water supply contamination is concerned) can 
affect PAGE behavior appreciably. 

I think you need to look elsewhere. What does "gels go bad"
mean exactly? What do you observe?
