For those of you following the ongoing mold saga, a wonderful new development has occurred. The source of water has been discovered. After removing the electric baseboard heater and more of the drywall (Thank you Paul for all your help.) we were able to visualize dripping water coming in through what appears to be a separation of the caulk surrounding the outside of the window. A simple fix. :)
The picture to the right is of the dead carpenter ants...also molding ...sigh.
However, in my search for the water source, I discovered that independent of the mold fiasco, I really do need a new roof. :( So I am pricing out different roofs. After the roof ... the leach field. It's all a work in progress.
