In Event 3 we saw how the springs and rivers became acidic and were contaminated with toxic metals.
Event 10 is a progression of Event 3. Living in the river beds are bacteria similar to those that live in the sea and cause “Red Tides”
They are called Extremophile Aerobic Bacteria because they thrive in acidic conditions.
These bacteria have also been found in caves in southern Mexico.
They live in an inhospitable environment where toxic Hydrogen sulphide gas spews out of the ground and neat Sulphuric acid drips from the roof.
In a very short time because of the high levels of acid in natural water resources, not only will these bacteria become prevalent in the world’s springs and rivers but also they will oxidize iron deposits turning them into rust. These bacteria give the appearance of blood just like the red tides in the oceans.
Revelation Chapter 16 V 4 says:
The third angel poured out his bowl on the rivers and springs of water, and they became blood. (NIV)
