There's a reaction between the chlorine used to get rid of bacteria and viruses like E.Coli etc. with the organic matter in the water from L. Mask. Even in a very clean lake like Mask there's always some algae present. In the past at least it was aggravated by the fact that they weren't using aluminium - especially to cater for dialysis patients using Baxter dialysis bags as I understood it. Aluminium is used to take out organic materials like algae from the water before it is chlorinated. So although we had very low aluminium the tendency to produce high trihalomethanes is much increased. With the E. coli thing I'm not surprised because two labs could give completely different answers on two different days simply because the bacteria come and go depending on rainfall, and what's happening nearby such as slurry spreading and loo-flushing into septic tanks.
