You need to call a water testing lab and have your water tested for VOC's. tell them your situation and they will come out and take a sample. In the mean time i would stop using this water for bathing and consumption. I also recommend calling your local health department so they are aware of possible contamination of other wells and what you should do with yours. If your neighbor has good water and is close enough, you might be able to run a hose from their outside spigot to yours and turn them both on. The water from their system will basically backfeed into your house. You will want to close the main valve coming off your holding tank. If you are able to get water from your neighbor, you will also want to flush your hot water tank and all the faucets but i still don't recommend drinking the water. The state might require that you fill the water that you flush from the hot water tank into drums. This is something that shouldn't be taken lightly.
