Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.
What is the electron transport chain's source of energy?
The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.
In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.
Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.

Homo sapien. Also known as Lucy
No need for evacuation but continue groundwater monitoring due to lower dose of toxic substance.
No need for evacuation, continue groundwater monitoring because the dose of toxic substance in a normal or safe range. In this range the toxic substance can't affect the health of people who drink that water.
If the dose of toxic substance increases more than 10 mg/ kg then the toxic substance killed people who drink that water. According to the graph, we can see that the dose is in a normal range so we can conclude that no need of evacuation for the people.
