There is something going on in my home and I need some suggestions. I moved there in May of last year. It seems everyone is having problems with their stomachs hurting. I find my liver hurts. Now what could cause this problem. It is town water. I think there was some mildew in the home and I also think it has something to do with septic. How can I figure this out. I might add the dog throws up alot and he stays clear of the living room. He goes into the garage to sit on the sofa or he hides in the bedrooms upstairs. Dogs usually sense when there is something wrong so I think the area involved is the living room area.
