Ill say the same advice I say to any person in shoes. Your first step should be to stop talking about it on public forums. As much as we LOVE to help, you could slip up and make a comment that could hurt you in a possible lawsuit. There are wayyyy to many factors for us that we'll never know for us to give you perfect advice. Talk to the pool-builder about your concerns. Let him know your worries..
