But if CCS operations leak, they can pose significant risks to water resources. That’s because pressurized CO2 stored underground can escape or propel brine trapped in the saline reservoirs typically used for permanent storage. The leaks can lead to heavy metal contamination and potentially lower pH levels, all of which can make drinking water undrinkable.
Can someone explain this to me in a easy way?
As a layman I would be worried of large amounts of CO² suddenly leaking near where people live. But how does it make water undrinkable? I thought some people like their drinks with CO². And where do the heavy metals come from?

High enough CO2 levels will make the water more acidic and could cause pipes to leach metals into the water.
I think the concern is more about brine that have heavy metals in them. Carbonated water is safe to drink, even if not safe for fish.
