Iheard that it is marsh gas. Which is formed from decaying vegetations under water. The main constituent of this gas is Methane. But methane is not toxic. So why the people entering these wells to clean and reopen it, died merly because of asphyxia or some other phenomenon.

I heard its Methane gas.

Carbon dioxide (molecular weight 44) accumulates in wells from the soil and air. It is heavier than air (average molecular weight about 29) and sinks to the bottom of wells because there are few currents to mix it up with air. It is poisonous in large concentrations but barely detectable to most people. It also accumulates in caves and sometimes in rarely used areas of mines.
Methane is NOT poisonous and is lighter than air (molecular weight 16), so will rise out of wells and poses no danger.

The gas formed are large amount of unused Uranium which causes asthma when inhaled and Plutonium another very good reactor fuel, which is produced as a by-product of running the reactor.

Methane, originated from decayed material. Highly poisonous.

Maybe they drowned. Entering a water well is not a very smart thing to do in any case.
