IF I am worried about pollution? I would be very ignorant if I wasn't. Shame on
anyone who isn't!
EGR isn't good in cold climates. Lots of shellacking, plugging up, etc., unless you use an elevated idle speed - 1000 RPM+. And though I am "up north", it's very mild here all winter long anyway - usually slightly above freezing all winter long.
Do you have good solid empirical data on water injection vs. emissions vs. g/hp-hr? I know the hot rodded diesel pickup guys use it to prevent unwanted large bangs when pushing hard.
