Interesting--I worked as a contractor in Vietnam and lost 2 of my employees to carbon monoxide. A pump in a well stopped working and the foreman went down in it, about 40ft, to see what wrong and the workers above saw him fall into the water and another one went down. He to fell in the water. When they were got out it was determined that the carbon monoxide had killed them. I had been down in that well myself no problem but we in the meantime had started a diesel power station right above the well. We were told that carbon monoxide had settled in the well because it was a heavier gas. Were we told wrong? I have always believed that since then.

Unless the exhaust pipe was faulty and was directing the exhaust right into the well, I doubt that was the issue.

There are plenty of other gasses which often seep into and are present in underground places like wells, tunnels, mines which are odorless and will kill you by suffocation.. Most common is Methane..

Miners of the old days used to take a canary into the mines, if it died, they knew it was unsafe and had to exit the mine.

Now days they do have special detectors which can test the air quality.

In reality a well should be treated like any enclosed or confined space, some sort of forced fresh air supply established and air quality should have been tested before someone enters..

HERE is a confined space primer..

It could have been, air currents and tempature plus humidity can redirect exausts. It could have been a fluke, some strage things do happen. Its like the opposite of a stack effect, there is a technical term I can not remember at the moment. It was most likely lack of oxygen because it was a confined space, as stated above.
