Advice on tough career/life choice...

This is a tough choice Steve. You chose to change careers to move into a field that almost certainly has a busy future. However you are forced to temporarily be away from the "things" that are most important to you in life. I have always made my choices by what I would or would not regret, or regret the most. With that being said, your family situation is high in the factors that will play a part in your decision, as it would be in mine. I would believe that the qualification you have acquired in the water industry will not be lost, and if you ever decided so, you could fall back on it. To me this offer sounds like a small blessing in disguise. I know.....no real help, but you can see which way I am leaning.
